Cyclone Phet : ウィキペディア英語版 | Cyclone Phet
Cyclone Phet (IMD designation: ''ARB 02'', JTWC designation: ''03A'', also known as Very Severe Cyclonic Storm Phet) was the third named cyclone of the 2010 North Indian Ocean cyclone season and powerful tropical cyclone. Phet developed from a low pressure area in the Arabian Sea that organized into a tropical cyclone on May 31. It initially moved to the northwest but later turned northwards before making landfall in the Oman Desert on June 4 at peak intensity. Weakening, it then shifted direction and headed northeast and made landfall as a deep depression at Thatta, Pakistan on the evening of June 6. Phet is a Thai word meaning Diamond. Damage from Phet in Oman was estimated to have exceeded $780 million. ==Meteorological history==
Early on May 30, the India Meteorological Department (IMD) and the Joint Typhoon Warning Center (JTWC) reported that an area of low pressure had formed about 925 km (575 mi), to the southwest of Mumbai, India. The area of low pressure had loose organized convection developing around the low level circulation center within the monsoon trough.〔 The system was located to the south of a high pressure center anchored over Oman in an area of moderate vertical windshear.〔 Early the next day as convection around the low level circulation center had consolidated further the JTWC issued a tropical cyclone formation alert whilst the IMD declared that a depression had formed out of the low pressure area and initiated advisories on it. Later that day the JTWC also initiated advisories on the Depression, designating it as Cyclone 03A as it had continued to consolidate despite moderate levels of vertical windshear. Early on June 1 as vertical windshear around the Depression had relaxed, the IMD reported that the depression had intensified into a cyclonic storm and named it as Phet. Later that day the JTWC reported that Phet had started to rapidly intensify before reporting that the system had intensified into a Category 1 tropical cyclone on the Saffir-Simpson hurricane scale. During the next day the JTWC reported that Phet had continued to rapidly intensify before reporting that it had initially peaked as a Category 4 tropical cyclone with winds of 230 km/h (145 mph). Phet hit the Arabian Peninsula shortly afterwards with hurricane-force winds, and then crossed into the Arabian sea and was downgraded to a deep depression before it hit Pakistan, dissipating on June 7. According to the IMD, Phet had the rarest of the rarest tracks with two landfalls and longest track in recent years.〔http://www.imd.gov.in/section/nhac/dynamic/pressrelease.pdf〕
