Severe Tropical Cyclone Larry (RSMC Nadi designation: 15F, JTWC designation: 17P) was a tropical cyclone that made landfall in Australia during the 2005–06 Southern Hemisphere tropical cyclone season. Larry originated as a low pressure system over the eastern Coral Sea on 16 March 2006 and was monitored by the Australian Bureau of Meteorology in Brisbane, Australia. The low-pressure area formed into a tropical cyclone two days later and quickly strengthened into a Category 5 storm on the Australian tropical cyclone scale. Larry made landfall in Far North Queensland close to Innisfail on 20 March 2006 as a Category 4 with wind gusts reaching and dissipated over land soon after. Throughout Queensland, Cyclone Larry resulted in roughly A$1.5 billion ($1.1 billion USD) in damage. At the time, this made Larry the costliest tropical cyclone to ever impact Australia; surpassing Cyclone Tracy in 1974 (not accounting for inflation). ==Meteorological history== Larry began as a low pressure system over the eastern Coral Sea that was monitored by the Australian Bureau of Meteorology from 16 March 2006. It formed into a tropical cyclone off the coast of Queensland, Australia on Saturday 18 March 2006. Larry was a Category 2 cyclone in the Australian intensity scale when the cyclone watch commenced, and gradually intensified to a high Category 4 on that scale. The eye of Larry crossed the coast near Innisfail between 6:20 am and 7:20 am AEST on 20 March 2006. According to preliminary data, the winds near Innisfail may have reached with gusts to . However, re-analysis based on land observations indicated that Cyclone Larry was a Category 4 cyclone during landfall, as wind gusts were estimated to have reached in the area of impact.〔(Larry was a category four cyclone: BoM. ) ABC News, 22 March 2007.〕 A month later, Cyclone Monica crossed the Queensland coast. The Australian intensity scale is based on maximum wind gusts, which are estimated to be 40 percent above 10-minute sustained winds. On this scale, Larry peaked as a Category 5 cyclone. On the Saffir-Simpson Hurricane Scale, the Joint Typhoon Warning Center's maximum 1-minute wind speed assigned to the cyclone define it as a Category 4 storm. Based on estimated winds speeds required to destroy simple structures, a damage survey of buildings in the Innisfail region estimated peak gust wind speeds (in reference to flat open country at a height of ) across the study area to range from . This estimate correlates with the Bureau of Meteorology's re-analysis of Cyclone Larry at landfall. Their reviews of data suggest that Larry was a Category 4 system when it crossed the coast.〔(【引用サイトリンク】title=Cyclone Testing Station )〕 It was confirmed by the Bureau of Meteorology in March 2007 that the cyclone made landfall as a Category 4 cyclone.〔 A 10-minute average wind speed of was reported in Innisfail during landfall,〔(【引用サイトリンク】title=History for Innisfail, Queensland on Monday, 20 March 2006 )〕 theoretically corresponding to 1-minute sustained winds of , and maximum wind gusts generally consistent with a Saffir-Simpson scale Category 4 storm.〔(BoM – Tropical Cyclone Frequently Asked Questions )〕 At 1 am Australian Eastern Standard Time on 21 March 2006, Larry was downgraded to a Tropical Low pressure system as it moved inland. Ex-tropical cyclone Larry was further tracked as it moved into western Queensland to the north of Mount Isa. Larry's short life as a cyclone is attributed to its speed; the system moved very quickly over the Coral Sea dissipating nearly 24 hours after landfall. Cyclone Larry was considered to be the worst cyclone to hit the coast of Queensland since 1931, until it was surpassed by Cyclone Yasi in 2011; consequently, the name "Larry" was retired on 12 December 2006.〔(Tropical Cyclone names )〕 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「Cyclone Larry」の詳細全文を読む スポンサード リンク
