Typhoon Neoguri (2008)
Typhoon Neoguri ( international designation: 0801, JTWC designation: 02W, PAGASA name: ambo ) was the earliest in the course of typhoon which hit the People's Republic of China. The first named storm of the Pacific typhoon season 2008, which took its name from the Korean word for raccoon dog, was formed on April 13 from a low pressure area east of the Philippine island of Mindanao. After crossing the island, the storm in the South China Sea intensified into a tropical storm. The atmospheric conditions were favorable for rapid intensification, and Neoguri acquired on April 16, the status of a typhoon. The typhoon reached on April 18, when approaching Hainan, its greatest strength, before turning to the north. Due to stronger wind shear and cooler water to Neoguri weakened rapidly and arrived on April 19 in the south of the People 's Republic of China as a minimal tropical storm over land.
In the south of the Philippines, the storm brought heavy rainfall with it. Heavy rain caused Neoguri in the People's Republic of China, where property damage of ¥ 296 million (2008: 42 million U.S. dollars, in current prices, 47 million U.S. dollars) was born.
Storm History
East -northeast of Palau was on April 11, a disorganized area of convection, which was in connection with a tropical wave, and was a low-pressure area between Palau and Yap in the system yet. Lying under a developing anticyclone managed the limited wind shear and increased Diffluenz very favorable conditions for the development of the system. By 13 April, a ground-level circulation had formed and began about 260 km southeast of Bislig City to consolidate Mindanao. Around the same time formed in the center reaching rainbands. On April 13, at 12:00 UTC, the Japan Meteorological Agency ( JMA ) classified the system as a weak tropical depression. The development of the system was a bit hampered when the system Mindanao and Negros crossed, but the circulation, further consolidated, while the Konvektionsbänder increased. During the day, the Philippine Atmospheric, Geophysical and Astronomical Services Administration ( PAGASA ) classified the system as Tropical Depression Ambo, and in the morning of April 14 classified the Joint Typhoon Warning Center ( JTWC ), the system as Tropical Depression 02W, as this is about 300 kilometers north of Zamboanga Peninsula was. At 03:00 clock UTC on April 14 Ambo was, according to PAGASA within Dumaguete City.
The depression moved westward along the southern periphery of a strong subtropical ridge, which stretched from Southeast Asia to the north of Luzon. When it arrived in the Sulu Sea to convection and circulation konsolierten further, the anticyclone in the amount provided for excellent discharge. Based on estimates using the Dvorak technique the JTWC classified the low pressure area at noon of April 14, a tropical storm high. On April 15, at 00:00 UTC, the JMA downgraded clock the system as a full-fledged tropical depression, and six hours later after the system was the island of Palawan crosses and passes into the South China Sea, the JMA said in Tokyo as the Regional Specialized Meteorological Centre ( RSMC Tokyo), the system to Tropical Storm Neoguri. Shortly afterwards, PAGASA issued the final warning because the hurricane had left their area of responsibility.
After the system had intensified to a tropical storm, the further development was limited somewhat by a slight increase in wind shear and the inhibition of the effluent. However, this stunt the further development was only temporary, and on 16 April, the organization had rapidly improved. As a result, the JMA downgraded Neoguri high to a severe tropical storm. Warm water temperatures further contributed to the intensification of the storm at, and in the center of the convection is an eye formed. At 12:00 clock UTC on April 16, the JMA classified Neoguri about 350 kilometers east of Qui Nhon, Vietnam as typhoon. An approximating subtropical trough steered the typhoon northwestward what the discharge intensified, thus further intensifying contributed. The JTWC represented the high point in the life cycle of the typhoon late on April 17, with one-minute sustained winds of 175 km / h fixed, as was the center near the Paracel Islands. The JMA assessed the climax concludes on the basis of ten-minute sustained winds of 150 km / h in the morning of the next day day when Neoguri was located about 190 kilometers east of Sanya on the southern tip of Hainan.
Typhoon Neoguri went through a cyclical Eyewall - formation, at about the time, developed its greatest strength in the typhoon; the inner eyewall and the outer eyewall kallabierte pulled up to a diameter of 65 km. After reaching the highest wind speed, the typhoon had turned to the north, and the China Meteorological Administration noted that Neoguri moved near Wenchang on the coast of Hainan. Other weather services reported that the typhoon was moving parallel to the east coast of the island, however, was above water. The effects caused by land and wind shear led to a weakening of the typhoon, the so weakened to a tropical storm until April 19. Cooler water contributed to further weakening and caused the extinction of the convection; the circulation rolled off. Before landfall in the ProvinzGuangdong west of Macao as a weak tropical storm turned Neoguri to North Northeast. Neoguri reached the Chinese mainland earlier than all other recorded tropical cyclones, about two weeks before the previous earliest date was set by Typhoon Wanda during the Pacific typhoon season 1971. Shortly after Neoguri had come overland, the JTWC issued its final warning, because the resolution of the system began.
Preparations and impact
As ambo ( the local name for the resulting Typhoon Neoguri in the Philippines ) hinwegzog directly over large parts of Visayas and Mindanao, PAGASA storm warning issued. Signal number one was issued for the south of Negros, to the south of the province of Cebu, Bohol, Southern Leyte, Siquijor and Camiguin. Later, the alert level was reduced and finally abolished when the storm Palawan and the South China Sea reached.
The tropical low pressure system resulted in parts of the Philippines to abundant precipitation, which also included Metro Manila. In Cebu City heavy rain led to flooding that forced 62 people from their homes. In the Camotes Islands violent waves brought a motor boat to capsize; one of the six people on board could not be saved. On the other hand, led the storm for several days to a relaxation of the week-long heat wave that prevailed in Luzon.
In the Chinese province of Hainan returned about 21,800 fishing boats before the storm in the ports back, and about 120,000 people were evacuated from fish farms and in low- lying coastal areas. The authorities interrupted the ferry traffic between Hainan and the Leizhou Peninsula on the mainland. At sea, waited 56 fishermen from near the Paracel Islands; 38 of them were rescued shortly after the storm, the remaining eighteen were initially missing. They were found after 30 hours. The ship on which they were, had sunk, and the crew had clung to debris and built rafts to survive in the water. Another 18 Chinese and 22 Vietnamese fishermen remained missing. On Hainan Neoguri interrupted the power supply for the city of Wenchang.
On the mainland ferry services between Hong Kong and Macao were briefly interrupted. At the Hong Kong International Airport is delayed more than 200 flights, 30 flights were canceled completely and 66 incoming flights were diverted. The Hong Kong Observatory for safety's sake demonstrated on April 17, a ready signal. A day later, was the signal number 3 raised due to strong winds; while it was the earliest date in the year in which this happened. On the mainland Neoguri led to heavy rainfall; one monitoring station reported a days of rain quantity of 237 mm. Strong wind damaged coconut and banana trees, the damage in agriculture amounted to over RMB 200 million (2008, $ 28 million; USD 31 million in today's prices ). The material damage to buildings and infrastructure reached 96 million RMB (2008, $ 14 million inflation- adjusted $ 16 million ). In China, three victims have been confirmed in connection with the storm. Two were buried by a mudslide on a road, another killed by one of them blown by the wind aluminum panel.
