Tropical Storm Vongfong, known in the Philippines as Tropical Storm Milenyo, affected both the Philippines and China after a deadly flood season. The 14th named storm of the 2002 Pacific typhoon season, Vongfong developed as a tropical depression on August 10. Initially it was disorganized due to hostile conditions, and it failed to intensify significantly before crossing the Philippine island of Luzon. There, flooding forced 3,500 people to evacuate their homes. In the Philippines, the storm killed 35 people and caused $3.3 million in damage. After affecting the Philippines, the tropical depression dissipated in the South China Sea, although it reformed on August 15. It moved northwestward, strengthening into Tropical Storm Vongfong. It brushed eastern Hainan before making landfall on August 19 in southern China near Wuchuan, Guangdong. Soon after it dissipated, the storm dropped heavy rainfall across the region, causing one traffic accident in Hong Kong and killing twelve people due to landslides. The storm destroyed 6,000 houses, mostly in Guangdong, and damage in the country totaled at least $86 million. ==Meteorological history== On August 8, an area of convection, or thunderstorms, formed to the west-northwest of Palau, with a weak circulation connected to the monsoon trough. The system had good outflow, although it was initially within an area of increasing moderate wind shear, which limited organization. Convection increased, and although the circulation was exposed, the shear later decreased enough for the system to organize into a tropical depression on August 10; the Joint Typhoon Warning Center (JTWC) labeled it as Tropical Depression 18W,〔 the Japan Meteorological Agency (JMA) labeled it as an unnumbered depression, and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) gave it the name Tropical Depression Milenyo.〔 Upon developing, the depression was located in an area of weak steering currents,〔 still connected to the monsoon rough,〔 and it moved slowly to the west-northwest. The thunderstorms continued to be sheared to the west of the circulation, which limited strengthening. On August 12, the JTWC briefly upgraded the system to a tropical storm after a temporary increase in thunderstorms, although the system soon weakened.〔 A ridge to the north caused a general westward track toward the Philippines.〔 With a fully exposed circulation,〔 the depression made landfall at 0800 UTC on August 13 near Infanta on the Philippine island of Luzon. It soon dissipated due to continued shear and land interaction.〔 The remnants continued westward into the South China Sea, and PAGASA and JMA both discontinued advisories early on August 14. However, on August 15, a tropical depression re-developed halfway between Vietnam and the Philippines, with a circulation exposed from the convection due to moderate wind shear.〔 That day, the JTWC initiated advisories on Tropical Depression 20W.〔 After redevelopment, wind shear continued to be a problem, with convection located southwest of the center.〔 Early on August 17, a pulse in the monsoon increased thunderstorms and allowed the system to become better organized.〔 The convection became more concentrated and the circulation less exposed.〔 As a result, the JMA upgraded the depression to Tropical Storm Vongfong early on August 18, still in the central South China Sea.〔 Around that time, the storm began moving more quickly to the northwest due to a developing ridge to its northeast.〔 Although the JMA estimated peak 10–minute sustained winds of only 75 km/h (45 mph),〔 the JTWC assessed Vongfong as continuing to intensify to peak 1–minute winds of 100 km/h (65 mph), early on August 19.〔 By that time, the storm was near Hainan, and at 1240 UTC that day, Vongfong made landfall in southern China near Wuchuan, Guangdong. It quickly weakened over land,〔 dissipating early on August 20 to the west of Guilin.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tropical Storm Vongfong (2002)」の詳細全文を読む スポンサード リンク
