2010 North Indian Ocean cyclone season
The cyclone season in 2010 Nordindik has no official boundaries as is usual in other basins, but runs throughout the year. However, the tropical cyclones form in this basin is usually from April to December, the months before and after the monsoon season, ie April / May and October / November are the most active. A tropical cyclone in the Indian Ocean is called the cyclone.
The Regional Specialized Meteorological competent Centre ( RSMC ) is the India Meteorological Department in New Delhi. This awards for those tropical cyclones that reach at least the status of a cyclone, a name. Low pressure areas ( depending on the wind speed Depression or deep depression ) are numbered consecutively, with the letters BOB indicates that the system formed in the Bay of Bengal. The letters ARB are mutatis mutandis to the Arabian Sea.
Through the Joint Typhoon Warning Center ( JTWC ) in Honolulu independent forecasts and warnings are issued for the U.S. facilities in the Indian Ocean. By the JTWC classification according to the Saffir -Simpson Hurricane Scale, the RSMC used for classification own criteria occurs at, which include the measurement of the ongoing wind speed is based on the basis of a three-minute observation.

Storms
Severe cyclonic storm Laila
On May 17, the India Meteorological Department ( IMD), a low pressure area to a tropical depression rated highly and classified it under the name BOB 01 The system was at this time about 930 km east- southeast of Chennai, India. The system intensified rapidly and reached on May 18, the intensity of a tropical cyclone, about 450 km east- southeast of Chennai and 1200 km south- south-west of Kolkata. Due to favorable conditions, Laila could intensify and was upgraded on May 19 at 6:00 UTC clock to a severe cyclonic storm. The proximity to the mainland and increased wind shear pointed to a weakening of the hurricane, which was located 120 km northeast of Nellore and 100 km southeast of Ongole at this time.
The cyclone crossed on May 20, 11:00 to 12:00 UTC clock at Bapatla in Guntur district of the coast of Andhra Pradesh. About Land of the cyclone rapidly lost strength, so the RSMC stopped the warnings on May 21.
Cyclonic Storm Bandu
On May 19, the JTWC noted that in the Arabian Sea has formed a tropical storm. The IMD classified the system during the day as depression and had the name ARB 01 to. A few hours later, the RSMC New Delhi rated highly the depression to a deep depression. On May 20, the RSMC system classified again. However, it could intensify again the next day and was finally classified as a tropical cyclone and was named Bandu.
On this day, the cyclone made the cargo ship Dubai Moon maneuver. The 23 crew members of the vessel were rescued by helicopters from the British frigate HMS Chatham. The driving off the Somali coast cargo ship sank later.
Very severe cyclonic storm Phet
On May 31, the IMD classified a low pressure area 925 km southwest of Mumbai to a tropical depression high and gave the system the name of ARB 02 The next day the system had intensified into a deep depression, the JTWC saw during the day to further intensify. The RSMC New Delhi declared the system on June 1, a tropical storm and assigned the name Phet. On 2 June, Phet intensified rapidly and was initially to severe cyclonic storm and then upgraded to a very severe cyclonic storm. On the south edge of a subtropical ridge Phet moved from its formation to be in a northwestern direction towards Oman.
The cyclone scwehnkte gradually northward and crossed the coastline north of Marira. Overland, he moved to the Gulf of Oman, which he reached at Sur. Over the water of the Gulf of hurricane was distracted by the influence of the west wind zone to the east and the train speed increased. This, the influence of the coast of Baluchistan and moderate wind shear led to the weakening Phets. As a tropical depression Phet passed the 15.7 - million -inhabitant agglomeration Karachi and came overland.
Total came by the effects of the storm by 44 people.
Depression BOB 02
On October 7 classified the India Meteorological Department, a low pressure area to a high depression and classified the system as BOB 02 At this time, the depression was located about 180 km southeast of Visakhapatnam. Later that day, the IMD noted that the system of Visakhapatnam away while retained its strength. A landfall was predicted for the section between Gopalpur and Paradip, but late on October 7, pulled the depression across Paradip. On October 8, the RSMC New Delhi reported a slight weakening of the system. During the day, the system continued to weaken and arrived at Kolkata in West Bengal for the second time over land. The system weakened on its way to the northwest further, was then detected by the jet stream and eventually absorbed into the morning of the 9th of October, an extratropical storm.
Deep Depression BOB 03
On October 13 classified the India Meteorological Department ( IMD), a low pressure area to a high depression and called it BOB 03 At this time, the depression was located about 700 kilometers east of Visakhapatnam. During the day, the system intensified further. On October 15, the IMD classified the system boots to a deep depression. On the night of October 16, the system came near Gopalpur over land and started early on October 16, losing power. During the day, the depression weakened into a remnant low.
Very severe cyclonic storm Giri
On October 20 classified the India Meteorological Department ( IMD), a low pressure area to a tropical depression high and classified it as BOB 04 At the time the system was about 250 km southwest of Sittwe, Myanmar. In the early morning of October 21, the depression intensified into a deep depression and on the same day the Joint Typhoon Warning Center classified ( JTWC ) Tropical Cyclone 04B as the system. Later, the system continued to intensify and was incremented by the IMD to cyclonic storm Giri. Until October 22, Giri strengthened to a very severe cyclonic storm. During the day the storm continued to intensify and became the strongest cyclone of the season. Giri reached the highest intensity with three minute continuous wind speeds from 165 km / h and a minimum of central air pressure of 950 hPa. The landfall of the cyclone was (formerly Arakan ) near the city Kyaukpyu in Rakhine State. At midnight on 22 October, the system started to weaken. As the system further pushed forward into the interior and reached the rugged mountain country of Myanmar, it weakened rapidly. At noon on October 23 to Giri had weakened to the cyclonic storm. The cyclone moved over land to the northeast and weakened during the course of the day further from; late on 23 October presented the RSMC New Delhi found that the cyclone had disintegrated into a remnant low.
Severe cyclonic storm Jal
On October 28, formed in the South China Sea, south of Vietnam, a tropical disturbance. Over the next few days the system moved westward and northwestward, where it intensified. On October 31, the system organized into a tropical depression. On November 1, the system crossed the Malay Peninsula and arrived south of Myanmar in the Bay of Bengal. The system moved westward and intensified.
On November 2, the IMD noted that the system has weakened into a low pressure area that existed but good prospects for a new emphasis. Late on November 3, gave the JTWC Tropical Cyclone Formation Alert from a. Early on November 4, the system classified the IMD high and classified it as Depression BOB 05 The Joint Typhoon Warning Center gave the system the name 05B. Early on 5 November, the IMD classified the depression to a Deep Depression high. This intensified further and was upgraded to a cyclonic storm. The system was given the name Jal. The Storm won in the next two days of strength and was upgraded on November 6, to a severe cyclonic storm. On November 7, began the decline of Jal. and a few hours later reported the RSMC the weakening into a cyclonic storm. During the day the JTWC downgraded Jal back from a Category 1 cyclone to a tropical storm and a few hours later, the RSMC New Delhi fixed that Jal has weakened into a deep depression. In this intensity level, the system drew several hours later at Chennai on land.
Overland, the system rapidly lost strength and was downgraded early on November 9 to depression and explained during the day to a remnant low. This remnant low moved on in a northwesterly direction and the IMD was assumed that this residual depth could reintensivieren in the northeast of the Arabian Sea, and when the system is in the early morning of November 9, the Arabian Sea reached reinforced the system actually something, but crossed the system is not as predicted the Arabian Sea, but moved to the west coast of India north. Due to the prevailing winds, the system soon came again over land and broke up.
The strong tropical rainfall associated with Jal conducted in Thailand, northern Malaysia, Sri Lanka and parts of the Indian state of Andhra Pradesh to floods, lost their lives by at least 118 people. The storm and flood -related property damage o, related to Jal were estimated at more than 1.7 billion U.S. dollars, most of which was attributable to Thailand.
Depression BOB 06
In early December formed over the Bay of Bengal, a low pressure system that slowly moved towards the Indian coast and thereby trained better. The India Meteorological Department (IMD ) classified the system on 7 December high to depression. At the time the system was about 450 km south- southwest of Visakhapatnam in Andhra Pradesh. Until landfall on December 8 at Bapatla the system migrated to the north- east. Overland, the system weakened shortly thereafter from a remnant low.
