Typhoon Conson (2010) : ウィキペディア英語版 | Typhoon Conson (2010)
Typhoon Conson, known in the Philippines as Typhoon Basyang, was the second tropical cyclone during the 2010 Pacific typhoon season to impact the Philippines. Developing out of a tropical disturbance east of the Philippines on July 11, 2010, Conson quickly developed as it tracked nearly due west. Favorable environmental conditions, such as low wind shear and warm sea surface temperatures, allowed the system to intensify into a severe tropical storm by July 12. Around the same time, the JTWC assessed the storm to have been equivalent to a Category 1 hurricane. The following day, Conson struck Quezon Province with winds of 100 km/h (65 mph)〔Wind speeds are listed by 10-minute standards unless otherwise noted.〕 before weakening. After crossing the archipelago, the storm entered the South China Sea where it was able to re-strengthen. By July 16, Conson attained typhoon status as it neared the southern Chinese island of Hainan. After brushing the island at peak intensity with sustained winds estimated at 130 km/h (80 mph), the storm weakened in the Gulf of Tonkin due to less favorable conditions. The storm eventually made landfall near Ha Noi, Vietnam on July 17 and dissipated the following day. In the Philippines, Conson produced widespread, torrential rains which triggered significant flooding. At least 76 people are known to have been killed across the country and 72 others are listed as missing. Preliminary damage estimates were placed at PHP189 million (US$4.1 million). In China, at least two people have been killed due to wind-related incidents. Hainan Province sustained significant damage from the typhoon, with damage estimated at ¥500 million (US$73.8 million). Widespread damage was reported in Vietnam where at least two people were killed and 17 others were listed as missing. ==Meteorological history==
Late on July 9, the Joint Typhoon Warning Center (JTWC), reported that a tropical disturbance had persisted within the vicinity of Yap island. Satellite imagery showed that the disturbance had a weak circulation which was stretching over Yap with disorganized convection.〔 The disturbance was located to the south of a tropical upper tropospheric trough and was in an area of weak vertical windshear.〔 During the next day, deep convection around the disturbance increased whilst a low to mid level circulation center appeared on satellite imagery. Early on July 11, the Japan Meteorological Agency (JMA) reported that the disturbance had intensified into a tropical depression, whilst the JTWC issued a tropical cyclone formation alert as the disturbance had consolidated and had multiple convective bands flowing into its low level circulation center.〔(【引用サイトリンク】title=Tropical Cyclone Formation Alert: 2010-07-11 06z )〕 During that afternoon the JTWC reported that the disturbance had intensified into Tropical Depression 03W and initiated advisories on the system, before reporting later that day due to favorable conditions it had intensified into a tropical storm. PAGASA also reported that afternoon that the disturbance had intensified into a depression and named it as Basyang. At 0000 UTC, the next day the JMA reported that Basyang had intensified into a weak tropical storm and assigned it the name Conson and the international designation of 1002. Twelve hours later, as Conson moved through favorable condition and along the southwestern edge of the subtropical ridge of high pressure, the JMA reported that the storm had rapidly intensified into a Severe Tropical Storm with windspeeds of 100 km/h (65 mph). Later that day at 1800 UTC the JTWC reported that after convection around the system had expanded and microwave imagery showed an eye like feature, Conson had intensified into a typhoon. The JMA also reported at 1800 UTC that Conson had reached its initial 10-minute peak sustained windspeeds of 110 km/h (75 mph) despite predicting that it would intensify into a typhoon before making landfall in the Philippines. Early on July 13 the JTWC also reported that Conson had reached its initial 1-minute peak sustained windspeeds of 130 km/h (70 mph).
