Season overview:
Pacific typhoon season 2008

Typhoon Neoguri (international name: 0801 , JTWC name : 02W , PAGASA name: Ambo ) was the earliest typhoon to hit the People's Republic of China during the year . The first named storm of the 2008 Pacific typhoon season , named after the Korean word for the raccoon dog , 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. Atmospheric conditions were favorable for a rapid intensification and Neoguri gained typhoon status on April 16. The typhoon reached its greatest strength on April 18 as it approached Hainan , before turning north. Due to stronger wind shear and over cooler water, Neoguri weakened rapidly and reached the south of the People's Republic of China on April 19 as a minimal tropical storm over land.

In the south of the Philippines, the storm brought heavy rainfall. Heavy rain also caused Neoguri in the People's Republic of China, where a damage of 296 million ¥ (2008: 42 million US dollars , in today's prices US $ 50 million) arose.

Storm course

Train

An area of ​​disorganized convection associated with a tropical wave existed east-northeast of Palau on April 11, and an area of ​​low pressure existed within the system between Palau and Yap . Lying beneath an evolving anticyclone , the limited wind shear and increased diffluence created very favorable conditions for the system to develop. By April 13, a low-level circulation had formed and began to consolidate about 260 km southeast of Bislig City on Mindanao. At about the same time, rain bands reaching into the center formed. At 12:00 UTC on April 13,  the Japan Meteorological Agency (JMA) classified the system as a weak tropical depression. The system's development was hampered a bit when the system crossed Mindanao and Negros , but circulation continued to consolidate as the convection bands increased. During the day, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) classified the system as Tropical Depression Ambo, and in the early hours of April 14, the Joint Typhoon Warning Center (JTWC) classified the system as Tropical Depression 02W when this was itself about 300 km north of the Zamboanga Peninsula . At 3:00 a.m. UTC on April 14th, Ambo was within Dumaguete City, according to PAGASA .

The depression moved further west, along the southern periphery of a strong subtropical ridge that stretched from Southeast Asia to north of Luzon. Than it is in the Sulu Sea arrived, to convection and circulation konsolierten on, the anticyclone in the amount provided for excellent discharge . Based on estimates using the Dvorak technique , the JTWC upgraded the depression to a tropical storm at noon on April 14th. At 00:00 UTC on April 15, the JMA classified the system as a full-fledged tropical depression, and six hours later, after the system crossed Palawan Island and entered the South China Sea, the JMA in Tokyo declared it a Regional Specialized Meteorological Center ( RSMC Tokyo ) the system for Tropical Storm Neoguri. Shortly afterwards, PAGASA issued the final warning because the cyclone had left their area of ​​responsibility.

After the system had intensified into a tropical storm, further development was somewhat limited by a slight increase in wind shear and the inhibition of outflow. This slowdown in development was only temporary, however, and by April 16 the organization had rapidly improved. As a result, the JMA upgraded Neoguri to a severe tropical storm. Warm water temperatures further contributed to the intensification of the storm, and an eye formed in the center of the convection . At 12:00 PM UTC on April 16, the JMA classified Neoguri about 350 km east of Qui Nhon , Vietnam as a typhoon. An approaching subtropical trough directed the typhoon northwest, which increased the discharge and thus contributed to further intensification. The JTWC identified the peak in the typhoon's life cycle late April 17, with one-minute winds of 175 km / h when the center was near the Paracel Islands . The JMA assessed the peak on the basis of ten-minute continuous winds of 150 km / h early the next day, when Neoguri was about 190 km east of Sanya on the southern tip of Hainan.

Typhoon Neoguri on April 18th

Typhoon Neoguri underwent cyclical re-formation of the eyewall around the time Typhoon was at its greatest strength; the inner eyewall calved and the outer eyewall contracted to a diameter of 40 miles. After hitting the highest wind speed, the typhoon had turned north and the China Meteorological Administration found Neoguri moving over the coast of Hainan near Wenchang . Other weather services said the typhoon was moving parallel to the east coast of the island but was above water. The effects of land and wind shear led to a weakening of the typhoon, which then weakened into a tropical storm by April 19. Cooler water added to the weakening effect and caused the convection to cease; the circulation rolled out. Before landfall in Guangdong Province west of Macau as a weak tropical storm, Neoguri turned north-northeast. Neoguri reached mainland China earlier than any other recorded tropical cyclone, roughly two weeks ahead of the earliest date set by Typhoon Wanda during the 1971 Pacific typhoon season . Shortly after Neoguri crossed land, the JTWC issued its final warning that the system was breaking up.

Preparations and implications

When Ambo (the local name for the emerging typhoon Neoguri in the Philippines) passed directly over large parts of Visayas and Mindanao, PAGASA issued storm warning signals. Signal number one was issued for the south of Negros, the south of the province of Cebu , Bohol , Southern Leyte , Siquijor and Camiguin . The warning level was later lowered and eventually lifted when the storm hit Palawan and the South China Sea.

The tropical depression resulted in heavy rainfall in parts of the Philippines, which also included Metro Manila . Heavy rain caused flooding in Cebu City , forcing 62 people to leave their homes. In the area of ​​the Camotes Islands , heavy swell capsized a motorboat; one of the six people on board could not be saved. On the other hand, the storm eased the week-long heat wave that prevailed in Luzon for a few days .

In China's Hainan Province, about 21,800 fishing boats returned to ports before the storm and about 120,000 people were evacuated from fish farms and low-lying coastal areas. Authorities interrupted ferry traffic between Hainan and the Leizhou Peninsula on the mainland. At sea, 56 fishermen waited near the Paracel Islands; 38 of them were rescued shortly after the storm, the remaining eighteen were initially thought to be missing. They were found after 30 hours. The ship they were on had sunk and the crew had clung to debris and built rafts to survive in the water. However, another 18 Chinese and 22 Vietnamese fishermen remained missing. On Hainan, Neoguri cut power to Wenchang City.

On the mainland, the ferry connections between Hong Kong and Macau were briefly interrupted. At Hong Kong International Airport , more than 200 flights were delayed, around 30 flights were canceled and 66 arriving flights were diverted. The Hong Kong Observatory showed a readiness signal on April 17th as a precaution . A day later signal number 3 was raised due to strong winds; this was the earliest date in the year that this happened. On the mainland, Neoguri resulted in heavy rainfall; a measuring station reported a daily rainfall of 237 mm. Strong winds damaged coconut and banana trees, the damage to agriculture totaled over 200 million RMB (2008, 28 million USD ; in today's prices 33 million USD). Property damage to structures and infrastructure reached RMB 96 million (2008, USD 14 million; adjusted for inflation, USD 17 million). In China, three victims have been confirmed in connection with the storm. Two were spilled in a mudslide on a street, and another died in a wind-blown aluminum panel.
