2012 Pacific typhoon season

The Pacific typhoon season in 2012 is an ongoing weather event under which the forming throughout the calendar year, tropical cyclones are summarized. Most tropical cyclones form in the Pacific Ocean west of the dateline and north of the equator, but from May to November. Such tropical cyclones are called typhoons. The east of the 180th meridian forming storms are the subject of the Pacific hurricane season of 2012.

Within the northwestern Pacific there are two meteorological organizations which assign names to the storms. This means that the same storm often receives two different names. The official designation by the Japan Meteorological Agency ( JMA ) is replaced by a tropical storm once it reaches continued at any point in the northwestern Pacific ten-minute sustained winds of 35 knots ( 65 km / h). The Philippine Atmospheric, Geophysical and Astronomical Services Administration ( PAGASA ), however, has tropical depressions names that form within the national responsibility or move there; this responsibility is roughly bounded between 115 ° and 135 ° east longitude and between 5 ° and 25 ° north latitude. PAGASA has also to be a local name, if the system has already been named by the Japan Meteorological Agency. Tropical depressions, which are observed by the U.S. Joint Typhoon Warning Center, will receive a number with the suffix W.

• 3.1 International name
• 3.2 Philippines
• 3.3 Deletion of name

Storms

Tropical depression

On January 1, the JMA began warnings to a weak tropical depression issue, which was located 75 km north-west of Kuala Terengganu. During the day the depression moved slowly towards the southeast before the far northwest of the Sultanate of Brunei broke up on the same day.

Tropical depression

On January 13, the JMA downgraded a low pressure area east-northeast of Singapore to a tropical depression high, but strong wind shear led to the system dissolved on 14 January. In Malaysia, the system caused some landslides, but otherwise no significant property damage in connection with the storm were reported.

Tropical Depression 01W

On February 15, south-west of the Marianas was a tropical disturbance. The next day the disturbance drifted and moved towards the west to the Philippines. After they moved into the South China Sea on 17 February, it was updated by both the JMA and JTWC from a tropical depression and got 01W identification. As on February 18 began moderate vertical wind shear, the depression weakened a little. 01W remained two days remain until February 21, started strong wind shear and the system weakened into a remnant low. Later that day, the remains of about 01W Vietnam went ashore and dissolved completely.

The depression caused in parts of western Philippines for heavy rains and flooding. At least two people were killed and one person reported as missing. Three houses were destroyed and five others damaged.

Tropical Storm Pakhar

On March 17, a tropical disturbance formed to the northwest of Palau. At this time, the fault was in an area of moderate vertical wind shear and unfavorable water surface temperatures. Due to a high pressure area, which was located northeast of the fault, the system was forced to head west to pull. Over the next few days the disturbance moved slowly over Visayas and Palawan until the JMA them updated on 24 March to a tropical depression. The next day, however, the JMA downgraded the low pressure area back to a fault, as its outer rain bands as well as its circulation center collapsed. Because of the low level wind shear and very effective water surface temperatures, the disorder has already been updated again to a tropical depression the next day in the South China Sea. These conditions could amplify the low pressure area on quickly, so it is amplified and given the name Pakhar into a tropical storm on 29 March. Early on March 30, the JTWC classified Pakhar to a Category 1 typhoon high since the storm began to form an eye. Because cold water surface temperatures close to the mainland the JTWC classified Pakhar down to a tropical storm early on 31 March. The following day the storm makes landfall over Vung Tau, Vietnam, and began to weaken. Early on April 2, downgraded the JMA Pakhar down to a tropical depression. The remnants of the storm moved over the next few days over Vietnam, Cambodia and Laos. On April 5 to Pakhar was completely dissolved.

Tropical depression

On April 4, a cluster of thunderstorms developed northwest of Hawaii to a low pressure area, as it drifted slowly southwest. On April 6, the system was exposed to a wide range of vertical wind shear as it moved further west. Later, the system showed subtropical characteristics and it increased again. On April 8, the area of ​​low pressure crossed the International Date Line and moved to the Pacific Northwest. Then, the JMA upgraded the system to a tropical depression. Two days later, on April 10, wind shear caused the weakening of the low pressure system. Late the next day the system was absorbed by a cold front north-east of Wake Iceland.

Tropical depression

On April 23, southeast of Palau was a tropical disturbance. The system slowly began to move west and to strengthen. On April 28, it organized itself near Mindanao more and the JMA downgraded the system boots to a tropical depression. On April 30, the storm reached Mindanao and caused torrential rain and strong wind. In the course of the day, the low pressure area moved further into the country and weakened into an area of low pressure air. On May 1, the system is completely dissolved.

Severe Tropical Storm Sanvu

On May 20, the JMA reported that 525 km southeast of Guam had formed a tropical depression. In the course of the 21st of May, the JTWC upgraded the system to a tropical depression also. Early on May 22, the JMA downgraded the depression to a tropical storm up and forgave the name Sanvu. As Sanvu late on May 23, an eye began to develop, the JTWC upgraded the storm to a typhoon Category 1 After the JMA Sanvu late highly rated on 24 May to a severe tropical storm, drew his eye on May 25, directly above Iwo Jima time. On May 26 caused strong vertical wind shear for a rapid slowdown Sanvus and his eye broke up. Then, the JTWC downgraded the typhoon late on May 26 to a tropical storm down. The JMA followed on May 27 with the gradation to an extratropical low. The remains of Sanvu dissolved on May 30 to complete.

Typhoon Mawar ( Ambo )

On May 29 was formed northwest of Palau, a tropical disturbance. On May 30, the disturbance began to pull to the northwest and to increase slowly. When organized the convection of the system strongly the next day, the JTWC issued a Tropical Cyclone Formation Alert. Later on May 31, both updated PAGASA and the JTWC the disturbance to a tropical depression. Therefore PAGASA forgave the local name Ambo. The depression continued its intensification and strengthened on 1 June in a tropical storm, which was given the name Mawar international. When Mawars organized convection on June 2, the JMA upgraded the storm to a highly severe tropical storm. The JTWC followed shortly thereafter and updated Mawar at a Category 1 typhoon. On June 3, the JMA upgraded the storm to a typhoon high. The JTWC followed later the same day and updated to a Typhoon Mawar Category 2 early on June 4 Mawar reached its climax with continuous wind speeds of 185 km / h as a Category 3 typhoon. However, this status could Mawar hold only briefly, for only 6 hours later he was only a Category 2 typhoon. This was due to strong vertical wind shear. On 5 June, Mawar had so weakened so that it was only a severe tropical storm. A day later, the storm was fully extratropical.

Typhoon Guchol ( Butchoy )

Late on June 7 was south-southeast of Pohnpei a tropical disturbance. The disorder was classified on 10 June by the JMA Tropical Depression and upgraded to Tropical Storm Guchol only one day out. Guchol intensified early on June 14 to a severe tropical storm and received from the local PAGASA name Butchoy, as the system moved into the Philippine area of ​​responsibility. Later on June 14, the JTWC classified Guchol high to a Category 1 typhoon. On 15 June, Guchol organized on, and the JTWC downgraded the system to a Category 2 typhoon up. Early the next day reached Guchol also according to the criteria of the JMA intensity of a typhoon. Guchol intensified further, first to a Category 3 typhoon and then to a Category 4 typhoon on the Saffir -Simpson scale used by meteorologists of the U.S. Navy, unofficial for the western North Pacific. Guchol was later even to a super typhoon. On June 18, vertical wind shear caused a slowdown Guchols to a Category 3 typhoon, a little later to a Category 2 typhoon. When Guchol increasingly moving towards the north, and finally, Japan goes ashore on the Kii Peninsula, the typhoon weakened into a severe tropical storm. On the morning of June 20 Guchol became extratropical.

Severe Tropical Storm Talim ( Carina )

On June 13, was over the South China Sea monsoon trough. A day later, an area deep air pressure formed within this monsoon trough. The area was located east of Hainan, China at this time. On June 16, the system began to separate from the monsoon trough and the JMA upgraded the area to a tropical depression. A day later, the low pressure area was located 470 km away from Hong Kong. Late reinforced on June 17, the low pressure area to a tropical storm and was named Talim. The following day, Talim remained almost stationary east of Hainan. On June 19, the JMA downgraded high the storm to a heavy tropical storm. A day later, on June 20 Talim was downgraded by the JMA to a tropical storm. At the same time the storm moved into the Philippine area of ​​responsibility and PAGASA placed the local name Carina, but he shortly afterwards left again. As the storm moved later that day in the Formosastraße, the JMA Talim downgraded to a tropical depression. In the late evening of June 20, the system was eventually reabsorbed by the monsoon trough from which it was created.

Tropical Storm Doksuri ( Dindo )

On June 21, east of the Yap Islands was a tropical disturbance that early on June 25, north of Palau, increased to a tropical depression. As the tropical depression moved into the Philippine area of ​​responsibility the next day, PAGASA forgave the local name Dindo. Later on June 26, the JMA downgraded high depression to a tropical storm, which was given the name Doksuri. Shortly thereafter, the JTWC Doksuri also updated to a tropical storm. The following day Doksuris circulation moderate wind shear was exposed. This meant that the JTWC downgraded Doksuri on 28 June to a tropical depression. However, on 29 June Doksuri could strengthen into a tropical storm again. At this time, the storm was located 100 km away from Hong Kong. Later that day, the storm goes Zhuhai in Guangdong province, China on land. Early on June 30, the JMA downgraded to a tropical depression Doksuri down as the storm moved further and further into the mainland.

Tropical depression

On June 26, southeast of Chuuk Atoll was a tropical disturbance. Late on June 28 the JTWC issued a Tropical Cyclone Formation Alert on the system, but canceled these 2 days later. On June 30, the JMA upgraded the disturbance to a tropical depression, considered these but later on the same day to a tropical disturbance down. On July 2, crossed the fault, the Bicol region, and later the region Luzon - Manila. Two days later, on July 4, the JTWC Tropical Cyclone Formation Alert a published again to the system when it reached the South China Sea. But when the system weakened more and more, the JTWC Tropical Cyclone Formation Alert the canceled again. On the same day, the disturbance degenerated into a remnant low.

Severe Tropical Storm Khanun ( Enteng )

Late on July 12, a large cluster of thunderstorms formed with a weak low pressure area northwest of Guam. The next day, the low pressure system began to show convection and to organize themselves so that the JMA downgraded it up late to a tropical depression on July 14. On July 16, the JMA downgraded the system to a tropical storm and named it up Khanun. Later that day, the JTWC also classified Khanun to a tropical storm up and called him Enteng PAGASA, as the storm moved into the northeast area of the Philippine area of ​​responsibility. Late on July 17, the JMA upgraded Khanun to a severe tropical storm with wind speeds of 95 km / h as the center of the storm moved directly from Okino Shima Erabu. The next day, the JMA downgraded the system, however, again to a tropical storm down just before Khanun Jeju reached. Khanun made ​​landfall over Mokpo, South Korea and therefore weakened early on July 19 near the Demilitarized Zone to a tropical depression off. Later Khanun became extratropical.

Typhoon Vicente ( Ferdie )

In an area of convection, from the Khanun was already on July 14, a tropical depression more, which was updated on July 18 by the JMA formed. On July 20, the JTWC Tropical Cyclone Formation Alert was one of to the system. As the depression moved into the Philippine area of ​​responsibility soon, PAGASA named it Ferdie. Late on the same day the JTWC classified the system as a tropical depression also high. After Ferdie moved into the South China Sea on July 21, updated the JMA and the JTWC later the system as a tropical storm and the JMA awarded the international name Vicente. On July 23, Vicente was upgraded by weak vertical wind shear and high sea surface temperature of the JMA to a typhoon. The JTWC upgraded Vicente to a Category 4 typhoon, so that experienced the most rapid intensification Vicente in the northwestern Pacific. 16:45 UTC clock the HKO gave the signal no. From 10, the first since Typhoon York in 1999. Later the typhoon made ​​landfall on Taishan, Guangdong, China. Since the storm was going across country, Vicente was downgraded by the JMA to a severe tropical storm and by the JTWC to a category 3 typhoon. Later that day, Vicente wandered further and further into the interior, where the system is weakened first into a tropical storm and eventually into a tropical depression. On July 26, Vicente pulled over Burma out of time and therefore also of the responsibility of the JMA.

In Hong Kong, which reached the typhoon in the early morning hours of July 24, 2012, at least 129 people were injured. Although in the meantime " Vicente " has been downgraded as a tropical storm, over 40,000 people were invited on the Chinese mainland, to leave their homes.

Typhoon Saola ( Gener )

On July 22, was east-northeast of Palau, a tropical disturbance that was classified by the JMA late on July 26 as a tropical depression. The next day the JTWC Tropical Cyclone Formation Alert one exclaimed to the system. Early on 28 July, the JTWC classified the system as a tropical depression, while the JMA, the system highly classified a tropical storm and assigned the international name Saola. On the same day Saola moved into the Philippine area of ​​responsibility of PAGASA and got the local name Gener. After PAGASA had forgiven the name, the JTWC also classified Saola high to a tropical storm. Early on July 29, the JMA upgraded Saola to a severe tropical storm. The meteorologists of JTWCs classified Saloa one day a typhoon category 1 up, as the storm began to develop an eye. After a slowdown of transient to a tropical storm to Saloa intensified again and also reached the criteria of the JMA typhoon. Typhoon Saloa even intensified in a Category 2 typhoon before he arrived on August 1 at 19:20 UTC clock in Hualien on the country of Taiwan. Late on August 2, downgraded the JMA down the typhoon to a severe tropical storm before it goes the second time at 22:50 UTC clock in Fuding, Fujian, China overland. The next morning, the JMA downgraded to a tropical depression Saola down because the JTWC already published his last warning to Saola. On 4 August, Saola dissolves on the Chinese mainland.

Typhoon Damrey

On July 26, a tropical disturbance formed south-west of Minami- Torishima. The next day, the JMA downgraded the disturbance to a tropical depression up and the JTWC Tropical Cyclone Formation Alert represented a made ​​to the system. That same day, the JMA upgraded the depression to a tropical storm and named this Damrey. Shortly thereafter, the JTWC and updated Damrey followed to a tropical depression. The next day, the JTWC also classified the system to a tropical storm up. Late on July 30, the JMA upgraded Damrey to a severe tropical storm, as Damrey began to form convection to its circulation. On August 1, the JTWC classified Damrey high to a typhoon category 1. In the early morning hours of that day Damrey Kyushu slipped and caused moderate flooding from. On August 2, the storm reached its peak intensity as a typhoon and showed a well- formed eye. As Damrey moved into the Yellow Sea on the same day, he began to form a ring-shaped structure. A short time later Damrey in Xiang Shui in the province of Jiangsu, China overland. Later, on August 2, the JTWC upgraded the typhoon to a tropical storm down and gave his last warning to Damrey from. The JMA followed early the next day and classified Damrey down to a severe tropical storm. On 4 August, Damrey dissolves completely on the Chinese mainland.

Typhoon Haikui

On July 31 was formed southeast of Iwo Jima, a tropical disturbance. The next day, the JMA upgraded the disturbance to a tropical depression and began to watch. The JTWC issued a Tropical Cyclone on August 2 Formation Alert on the system and rated it the same evening to a tropical depression up. Early the next day, the JMA upgraded it to a tropical storm, the name Haikui received after the Chinese word for sea anemone. Early on August 4, the JTWC Haikui also updated to a tropical storm. When Haikui north-northeast was of the Okinawa Islands on August 5, the JMA downgraded the system to a heavy tropical storm high. As Haikui late on August 6 showed a well-defined eye, the JTWC upgraded the storm to a Category 1 High - typhoon. Just one day later, the JMA Haikui updated to a typhoon. Later that day, the storm is at its highest intensity in Zhejiang Province, China on land. During the next morning the JTWC issued its final warning to Haikui, the JMA upgraded the typhoon to a severe tropical storm down. As Haikui ever moved during the day into the country, he continued to decelerate from a tropical storm. Overland, the storm finally weakens to a tropical depression off and raises up early on August 11.

In Shanghai, where 400,000 people had been evacuated by the authorities, two people lost their lives that were hit by falling debris. In Zhejiang Province, 1.5 million people were evacuated. The local dished economic damage by Haikui is estimated at around 635 million euros.

Severe Tropical Storm Kirogi

On August 3, the JMA reported that a tropical depression had formed within a monsoon trough. At this time she was 735 km northwest of Wake Iceland. The following day the JTWC Tropical Cyclone Formation Alert a published to the system, describing it as subtropical. Later that day the JTWC upgraded it also as a tropical depression. After promotion to a tropical depression, the JTWC upgraded the system on August 5, to a tropical storm. However, early on August 6, the JMA reported that the system was to extratropical. Two days later, on August 8, the JMA reported a regeneration into a tropical storm and named this Kirogi. Early on August 9, the JTWC classified Kirogi down to a tropical depression. Later, however, the same day the JMA did the opposite and updated Kirogi in a heavy tropical storm. Therefore, the JTWC classified the system again to a tropical storm up. On the evening of that day the JTWC final warning to Kirogi issued. However, the JMA continued to write warnings to Kirogi and posted on August 10, a landfall over the southern Kuriles before the storm became extratropical later that day for the JMA.

Tropical depression

On August 5, was east-southeast of Midway Island, a non- tropical low pressure area. After the low pressure area on August 7, crossed the International Date Line and moved to the Pacific Northwest, the JMA reported the system early on 9 August as a tropical depression. On August 11, the tropical depression moved back, however, in the central Pacific, and so left the responsibility of the JMA.

Typhoon Kai- tak ( Helen )

Late on 10 August was to the west of Guam, a tropical disturbance. Early the next day was the JTWC Tropical Cyclone Formation Alert from one to the system and the JMA upgraded it to a tropical depression. On August 12, PAGASA downgraded the system to a tropical depression up and forgave the local name Helen. Later that day the JTWC upgraded it as a tropical depression 14W. The next morning, both the JMA and the JTWC downgraded the depression up to a tropical storm. The JMA awarded the international name Kai - tak. At 17:00 UTC on August 14 clock goes Kai- tak in the province of Cagayan in the Philippines over the country. As Kai- tak moved to its landfall in the South China Sea, and again met with warm water, the JMA upgraded the system to a heavy tropical storm. This was followed by the JTWC classified and Kai- tak on the evening of August 15 at a Category 1 typhoon high. Early on August 17, the JMA also upgraded Kai- tak to a typhoon before it goes for a second time on land at 4:30 UTC clock in Zhanjiang in Guangdong Province, China. Since Kai- tak was going across country, the JMA upgraded the typhoon to a severe tropical storm down. As Kai- tak increasingly moved into the mainland, the JMA downgraded the storm to an area of low pressure air.

Typhoon Tembin ( IGME)

On August 16, southeast of Taiwan was a tropical disturbance. The next day the JMA updated the error to a tropical depression. Late on August 18, the JTWC issued a Tropical Cyclone Formation Alert on the system. Early on August 19, the JMA downgraded the depression to a tropical storm and named this high Tembin. The JTWC upgraded Tembin later the same day to a tropical depression. Shortly after this happened updated PAGASA the system to a tropical depression and assigned the local name IGME. On August 20, Tembin launched a rapid intensification due to very favorable conditions. Immediately updated both the JMA and the JTWC the storm to a typhoon. On the same day Tembin by 0 clock to a Category 1 typhoon, by 6 clock to a Category 2 typhoon and by 12 clock to a typhoon Category 3 The typhoon reached its peak at 18 clock on 20 August with top speeds of around 215 km / h and a minimum air pressure of 950 hPa as a Category 4 typhoon. During the following day, Tembin weakened again in a typhoon Category 3. As the typhoon on August 22, a cyclic - eyewall formation underwent, he initially weakened to a Category 2 typhoon and later to a Category 1 typhoon. On August 23 Tembin could but again decreased rapidly intensify to a category 3 typhoon and went at 21.00 UTC clock on the extreme southern Taiwan on land. Two hours after landfall reached Tembin the Formosastraße where the JMA downgraded the typhoon early on 24 August to a heavy tropical storm. The JTWC followed and downgraded Tembin to a tropical storm. When the storm on the same day in the South China Sea moved and rebuilt a circulation, the JTWC Tembin updated to a Category 1 typhoon. After the JMA late on August 25 also did this, the JTWC Tembin saw in the early morning of August 26 as a Category 2 typhoon. Six hours after the promotion to a Category 2 typhoon Tembin the JTWC upgraded again to a typhoon Category 3 After the typhoon on the east coast of Taiwan was pulled along, he weakened on August 28th in a severe tropical storm off. Also, the JTWC classified Tembin into a tropical storm. On August 30 Tembin went to South Korea to land and quickly became extratropical by the cooler waters.

Typhoon Bolaven ( Julian )

Late on 17 August was a tropical disturbance southwest of Guam. On August 19, the JMA upgraded the disturbance to a tropical depression, while the JTWC Tropical Cyclone Formation Alert a published to the system. The next day both the JMA and the JTWC upgraded the depression to a tropical storm. The JMA then forgave the name Bolaven. Early on August 21, the JMA upgraded to a Severe Tropical Storm Bolaven. While the JMA Bolaven highly rated on the same day later to a typhoon, the JTWC upgraded the storm to a Category 1 typhoon. Over the next few days, Bolaven rapidly reinforced and developed on August 24, a well-defined eye. This prompted the JTWC to hochzustufen Bolaven into a Category 4 typhoon. As the typhoon moved into the Philippine area of ​​responsibility later forgave the local PAGASA name Julian. After Bolaven had reached its climax, and passed over the Okinawa Prefecture on August 26, the typhoon weakened into a typhoon Category 3. The following day Bolaven changed course and moved from then head north - northwest into the Yellow Sea. Here, Bolaven rapidly weakened into a tropical storm and went 28 August North Korea on land. On August 29, Bolaven became extratropical over China. Beginning of September, Bolaven sparked north of Andreanof Islands to complete.

Tropical depression

On August 23, was south-southwest of Jeju- do, South Korea, a tropical disturbance. On the same day, the JMA upgraded the disturbance to a tropical depression. Two days later, she goes to North Korea on land and dissolves.

Typhoon Sanba ( Karen )

On 8 September, formed south of Guam, a tropical disturbance. As the system moved westward and organized itself more and more, the JMA downgraded it on September 10 in the vicinity of Palau to a tropical depression up. Later that day, the JTWC issued a Tropical Cyclone Formation Alert on the system. The depression moved further west and the JTWC issued warnings to the tropical depression. As the system moved into the Philippine area of ​​responsibility on September 11, PAGASA placed the applicable there name Karen. At the same time, the JMA downgraded the depression to a tropical storm up and called this Sanba. As Sanba on September 12, formed a weak eye, the JTWC upgraded the storm to a typhoon high category 1. Shortly afterwards, the JMA Sanba updated to a heavy tropical storm. Late on September 12 Sanba began to rapidly intensify and the JMA upgraded the storm to a typhoon high. The following day, the JTWC reported that Sanba had strengthened into a category 2 typhoon, as the typhoon began to form a well-defined eye. Later that day, sat Sanba continues its explosive intensification and strengthened to a Category 4 typhoon. Later on September 13, the JTWC reported that Sanba have intensified into a super typhoon category 5, the strongest since Megi weaken from the year 2010. On 15 September Sanba began in a Category 3 typhoon and the well-defined eye disappeared because of a cyclic - eyewall formation. On September 17, at 1:00 UTC clock Sanba goes to South Korea on land and then rapidly weakened into a tropical storm off before it made its second landfall over southeast Russia and soon became extratropical on September 18.

Tropical depression

An original height depth parted late on 9 September in two small tropical disturbances. The following day, the JMA upgraded an interference that was located south-east of Tokyo, to a tropical depression. On the same day she began to the south of the system to interact with the other disorder. On September 11, the circulation of near depression has been exposed to the disturbance before it completely absorbed early on September 12. Later that day, the depression reached its peak. The next day, however, disbanded the circulation of the system and wind shear began. So it came about that the depression became extratropical on September 13 later.

Typhoon Jelawat ( Lawin )

Late on September 17 was a tropical disturbance east of Guam. Early on September 20, the JMA upgraded the disturbance to a tropical depression up. Shortly thereafter, the JTWC Tropical Cyclone Formation Alert a published to the system. Eight hours later updated PAGASA the system to a tropical depression and assigned the local name Lawin before the JTWC, the system now up classified as a tropical depression. On the night of 21 September, the JMA upgraded the depression to a tropical storm and named this Jelawat. So did the JTWC. On the afternoon of the same day, the JMA Jelawat classified to a severe tropical storm up. Early on 23 September, updated, both the JMA and the JTWC Jelawat to a typhoon, when the storm began an explosive development. This was reinforced by a typhoon Jelawat category 1 in a typhoon category 4 On September 24, the JTWC upgraded the super typhoon to a typhoon category 4 down because Jelawat began a Cyclic Eyewall - formation. As the typhoon had undergone this, he was able to strengthen early, according to the JTWC on 25 September at a Category 5 typhoon. The following day the JTWC downgraded Jelawat to a super typhoon category 4 down, as he launched a Cyclic - eyewall formation. On September 27, reports the U.S. Navy 's Joint Typhoon Warning Center ( JTWC ), the 760 km south- southwest of the island of Okinawa was the eye of the typhoon and the typhoon had an area of ​​over 1000 km. The typhoon developed at this time, peak wind speeds of 250 km / h in individual gusts to 305 km / h Jelawat changed its direction of pull from northwest to northeast in the direction of the Japanese islands. In the Philippines, three people came through Jelawat to death and the typhoon caused severe flooding. According to the National Disaster Risk Reduction and Management Council 3096 households were affected in almost all regions of the Philippines. By the morning of 28 September Jelawat could keep the Category 4 status until it weakened at noon of that day in a typhoon Category 3, and on the evening of 28 September crossed the Okinawa Islands. On September 29, the JTWC Jelawat classified into a category 2 typhoon down. The eye of the typhoon was located 260 kilometers northeast of Okinawa and was moving at 29 km / h in northeast, but he produced up to 10.5 meters high waves. On the evening of 29 September to Jelawat weakened due to its tensile direction to northeast and the cooler waters in a typhoon category 1 with an unusually low air pressure of 945 hPa. On September 30, the JTWC downgraded the typhoon back into a tropical storm before he goes ashore on Japan. Just one day later Jelawat became extratropical. The extratropical system of Jelawat was persecuted to the Andreanof Islands.

Severe Tropical Storm Ewiniar

Early on September 22, was west of Guam, a tropical disturbance. The following day, the JMA downgraded the disturbance to a tropical depression up. On 24 September, the JTWC upgraded the system to a tropical depression as it organized itself more and more. Because of the strong typhoon Jelawat west lay of the depression, he blocked the outflow channel, so that they initially could not evolve. When the depression late on September 24, but further and further from Jelawat and organized itself, classified both the JMA and the JTWC it up to a tropical storm. The JMA awarded the international name Ewiniar. Over the next two days, Ewiniar away further and further from Jelawat and could amplify on 26 September to a severe tropical storm thus, according to the JMA. Ewiniar could on the next two days due to wind shear and its position, which was located far to the north, no longer continue to develop and the JMA downgraded Ewiniar on 29 September by a heavy tropical storm to a tropical storm down. On September 30, Ewiniar became extratropical.

Severe Tropical Storm Maliksi

On September 27, a tropical disturbance formed in the vicinity of Chuuk Atoll. On September 29, the JMA upgraded the disturbance to a tropical depression. Two days later, on October 1, both the JTWC and the JMA the depression to a tropical storm classified high and the JMA forgave the name Maliksi. On October 3, the JMA Maliksi updated to a heavy tropical storm as it moved directly over Iwo Jima. Cooler waters and strong wind shear could Maliksi on October 4, be extratropical.

Severe Tropical Storm Gaemi ( Marce )

On September 29, the JMA reported that a tropical depression had formed within a monsoon trough. When the system was upgraded to a tropical depression, it was located approximately 745 km north-west of Ho Chi Minh City. Over the next day, the depression was able to organize more and more, as they stationary west of the Philippines was. As on October 1, the system formed a good circulation, updated both the JMA and the JTWC it to a tropical storm. The JMA awarded it their international name Gaemi. Two days later, on October 3, strengthened Gaemi was according to the JMA to a severe tropical storm as it is very slow moving and still quasi-stationary west of the Philippines. At this time ruled by Gaemis circulation around heavy rainfall, of which, however, no region was directly affected. Only in the Philippines brought Gaemi moderate rainfall, as its rain bands roamed the land. As Gaemi moved into the Philippine area of ​​responsibility between the same evening, PAGASA forgave the local name Marce. The following day, sat moderate vertical wind shear from the east and weakened Gaemi, so its circulation is largely disbanded and it weakened into a weak tropical storm. At 07:00 UTC on October 6 clock goes Gaemi as a tropical storm on Phú Yên ashore. Overland Gaemi quickly lost its tropical characteristics and became extratropical on October 7 about Cambodia. The remains of Gaemi caused heavy rains over Thailand and closed on 9 October in the Nordindik to regenerate there in the Depression BOB 01.

Typhoon Prapiroon (Nina )

On October 3, formed over the western Pacific, a large tropical wave. Early on October 5, the JMA upgraded the shaft to a tropical disturbance. A little later, the JMA downgraded the fault north of Guam up to a tropical depression. On October 7, the JMA upgraded the depression to a tropical storm and named this Prapiroon. This did the JTWC little later. As Prapiroon moved into the Philippine area of ​​responsibility on October 8, PAGASA forgave the local name of Nina. Later that day, the JMA downgraded Prapiroon to a heavy tropical storm up, as he is always better organized and a very good circulation formed. On October 9, updated both the JMA and the JTWC Prapiroon to a typhoon, at this time the eye of the typhoon was located 910 km east of the municipality of Aparri. On the night of October 10, the JTWC downgraded Prapiroon to a typhoon category 2 up, as the system formed a visible eye. The JTWC reported on 11 October, the Prapiroon peak wind speeds of 175 km / h reached in individual wind gusts to 215 km / h and there was the eye of the typhoon 770 km south of the island of Okinawa. The foothills of the storm reached the northern Luzon, the Batanes, Babuyan Islands and Taiwan. The typhoon moved with a forward speed of 13 km / h in west-northwest direction. Prapiroon turned on October 12 at a Northeast bearing and could amplify on October 12 at 0:00 clock to a typhoon Category 3. This status was given by the typhoon but only briefly, because only 6 hours later the JTWC reported the attenuation in a Category 2 typhoon. After reaching the peak Prapiroon began to weaken slowly and the JTWC reported on the morning of 13 October, that the system had weakened to a Category 1 typhoon. On 15 October, the typhoon moved once in all directions as he made a small loop and ring-shaped structures showed. On October 16, the JMA upgraded the typhoon to a severe tropical storm down, as occurred gradually bad conditions. Soon afterwards the JTWC Prapiroon classified into a strong tropical storm down. After the downgrade Prapiroon remained a tropical storm for 3 days until he transformed himself into a extratropical cyclone on October 19.

Severe Tropical Storm Maria

On October 13, the JMA reported that a tropical depression had formed weak; this was according to the JTWC at this time about 50 nautical miles east-southeast of Pagan. As it moved towards the west on October 14, it intensified into Tropical Storm Maria. Maria continued her rapid development continued and intensified later became a severe tropical storm. Over the next few days saw wind shear for a rapid attenuation of Mary. On the morning of October 20, the storm transformed into an extratropical cyclone and was at the same evening absorbed by the extratropical low of Prapiroon.

Typhoon Son - Tinh ( Ophel )

On October 19, a tropical disturbance originated southeast of the Yap Islands. Two days later, on October 21, the JMA upgraded the disturbance to a tropical depression. On October 22, PAGASA downgraded the system to a tropical depression up and called this Ophel. First of Ophel could develop only slowly until the system on 23 October showed a circulation and has been updated as of the JMA and JTWC to a tropical storm. The JMA awarded it their international name Son - Tinh. Son - Tinh already reached on the following day, the Philippines and went on Leyte on land and therefore had no time to develop. About many small Philippine islands Son Tinh initially could not intensify. However, when he reached the South China Sea on October 25, the JMA reported surprising that Son - Tinh had intensified into a Severe Tropical Storm. The storm moved strictly further west - north-west and south-east of Hainan made ​​it a well - visible eye, which both the JTWC and the JMA prompting, Son Tinh heraufzustufen to a typhoon. On October 27, the storm had arrived in the Gulf of Tonkin and reinforced there rapidly into a Category 3 typhoon with maximum speeds of 205 km / h Son - Tinh weakened due to the proximity to the mainland after the 24 - hour hold, Category 3 on 28 October at 12:00 UTC clock in a Category 2 typhoon on. With wind speeds of 165 km / h, the typhoon is the afternoon of the same day near the northern Vietnamese city of Haiphong on land. Shortly thereafter, Son Tinh weakened into a typhoon category 1. After weakening to a tropical storm Son - Tinh pulled deeper and deeper into the mainland and broke away on the morning of 30 October.

Tropical Depression 25W

On November 6, a tropical disturbance developed south of the Mariana Islands. Due to strong wind shear and other bad conditions, the disorder was initially able to organize only very slowly as she approached the Philippine Sea. On November 11, the system crossed the Philippines completely, reaching on 12 November the South China Sea. There was the problem on the same day 240 km north -northwest of Kota Kinabalu, updated in the state of Sabah, Malaysia by the JMA in a tropical depression. Because of moderate vertical wind shear, the tropical depression was no longer develop, but reached on 14 November its peak. The very next day she went near Ho Chi Minh City ashore and broke up then overland to.

Typhoon Bopha ( Pablo)

On November 23, the JTWC noted that about 350 nautical miles south of Pohnpei had only 0.6 degrees north of the Equator formed a large area of convection. The system could be organized over the next few days due to warm sea surface temperature, so it has been classified by both the JMA and JTWC as the tropical depression on November 25, and at the same time received the designation 26W by JTWC. In the early hours of November 26 formed over the center in the height of an anticyclone with nearly radial outflow and low vertical wind shear. Under the influence of this anticyclone, the system steadily intensified and reached at the end of the day the strength of a tropical storm. The JMA gave the system so the name Bopha. As on November 27 was formed deep and intense convection, and the JTWC downgraded the system to a tropical storm up.

Located south of Bopha forming at the equator storm made ​​for a strengthening of the storm and on 30 November the system had intensified into a severe tropical storm. That same day, provided the JTWC noted that Bopha had an eye formed and classified the storm therefore as Category 1 typhoon a. At this time began an explosive intensification, and Bopha reached according to the methodology of the JTWC only 18 hours later, on December 1, the intensity of a Category 4 typhoon. This development was unusually far south, in the course of the fifth degree of north latitude. Usually, the development of tropical cyclones in this area is severely limited because the necessary development to Coriolis force is small. On December 2, Typhoon Bopha reached with wind speeds of 250 km / h, reaching its peak at about this time the responsibility of PAGASA and got the local name Pablo assigned. On the night of December 3 to Bopha weakened unexpectedly and was only a Category 3 typhoon. During the day the 3rd of December, however, Bopha began shortly before reaching the Philippine island of Mindanao once again a tremendous intensification and strengthened within 12 hours by a typhoon Category 3 to a Category 5 typhoon Bopha was next Sanba and Jelawat already the third typhoon in 2012, to have managed this. Late in the evening of the same day Bopha went with wind speeds of up to 210 km / h over Mindanao on land and so was the strongest typhoon that it ever did. According to the authorities at least 546 people were killed, hundreds more are still missing. Most people arrived in the province of Compostela Valley on the east side of the island of Mindanao by flash floods killed. After Bopha is moving away in the South China Sea from the southern Philippines, it weakened to a tropical storm and turned on a northerly course. On December 7, Bopha was in the early hours but back to a category 1 typhoon and strengthened only 6 hours to a Category 3 typhoon. The typhoon again formed a visible eye and turned gradually to a north-east course, which led him to the west coast of Luzon. As fast as Bopha again intensified, he weakened due to strong wind shear it off again, so that the JTWC and the JMA on December 9, released their last warnings.

Tropical Storm Wukong ( Quinta )

On December 20, southwest of Pohnpei was a tropical disturbance. The disturbance strengthened in the next few days getting better and was therefore promoted on 24 December of the JMA, the JTWC and PAGASA from the east of Mindanao to a tropical depression. PAGASA awarded it their local names Quinta. Just before the low pressure area on 25 December, the Philippines attained, it has been updated by the JMA and JTWC from a tropical storm Wukong. On December 26, Wukong went over Visayas ashore. After landfall, the storm moved on many Philippine islands, reaching on 27 December the South China Sea and weakened there into a tropical depression from which dissolved the very next day.
