Super Typhoon Haiyan is one of the most intense tropical cyclones in world history, with sustained winds an incredible 190 mph, gusting to 230 mph, said the Joint Typhoon Warning Center in their 15 UTC (10 am EST) November 7, 2013 advisory. Officially, the strongest tropical cyclone in world history was Super Typhoon Nancy of 1961, with sustained winds of 215 mph. However, it is now recognized (Black 1992) that the maximum sustained winds estimated for typhoons during the 1940s to 1960s were too strong. Since 1969, only three tropical cyclones have equaled Haiyan’s 190 mph sustained winds–the Western Pacific’s Super Typhoon Tip of 1979, the Atlantic’s Hurricane Camille of 1969, and the Atlantic’s Hurricane Allen of 1980. All three of these storms had a hurricane hunter aircraft inside of them to measure their top winds, but Haiyan’s winds were estimated using only satellite images, making its intensity estimate of lower confidence. Some interpretations of satellite intensity estimates suggest that there may have been two super typhoons stronger than Tip–Super Typhoon Gay of 1992, and Super Typhoon Angela of 1995. We don’t have any measurements of Haiyan’s central pressure,but it may be close to the all-time record of 870 mb set by Super Typhoon Tip. The Japan Meteorological Agency estimated Haiyan’s central pressure at 895 mb at 12 UTC (7 am EST) November 7, 2013. Haiyan has the most spectacular appearance I’ve ever seen on satellite loops, with a prominent eye surrounded byahuge,impenetrable-looking mass of intense eyewall thunderstorms with tops that reach into the lower stratosphere. With landfall expected to occur by 21 UTC (4 pm EST) on Thursday, Haiyan doesn’t have time to weaken much before landfall, and will likely hit the Philippines at Category 5 strength. 文中提到的是,可能有3個颱風.已超越或媲美颱風之王-1979Tip(狄普) 分別是1992Gay(蓋伊) , 1995Angela(安琪拉) , 2013Haiyan(海燕) . 這三者在德沃夏克分析法評定衛星雲圖能顯示T值達8.0以上回顧幾個經典颱風海燕-可說是追風以來最為完美的一次. 今年颱風季前預測,就想說會不會有十分萬能的颱風. 現在想起回顧,海燕就是這種.超颱的條件他全部都達到.. MET 8.0 也是首次聽過!! 2013 Haiyan 海燕颱風 JTWC : 895hPa 170kts JMA : 895hPa CWB : 63m/s http://ppt.cc/2lzT http://ppt.cc/-Yau 全球的妮妲-仔細回顧,變成海燕的弱化版.起初兩家機構達到Adj 7.7和7.9. 可惜隔年被梅姬蓋去. 名氣已逐漸衰弱. 2009 Nida 妮妲颱風 JTWC : 907hPa 155kts JMA : 905hPa CWB : 58m/s http://ppt.cc/VXK0 妮妲的全球的正好衛星沒有照到巔峰.. 蓋伊-小時後剛有電腦網路時,1997年艾文, 瓊恩, 帕卡, 凱斯和東太平洋的琳達和1998年的瑞伯. 一直認為他們是1990-99最強者王者. 翻翻數字台風網和NOAA數據才知道,原來還有比這些更強的颱風. 原來存在於95, 92, 91和90年.而蓋伊則是92年. JTWC給他強度與梅姬和1997年那5個一樣的持平. 1992 Gay 蓋伊颱風 JTWC : 872hPa 160kts JMA : 900hPa CWB : 60m/s http://ppt.cc/1dX- http://ppt.cc/YfAl 全球的 1991年-2013年-西太 JTWC 美軍聯合颱風警報中心 2013海燕 Haiyan 895hPa 170kts 1992蓋伊 Gay 872hPa 160kts 1997艾文 Ivan 872hPa 160kts 1997瓊恩 Joan 872hPa 160kts 1997帕卡 Paka 901hPa 160kts 2010梅姬 Megi 903hPa 160kts JMA 日本氣象聽 2010梅姬 Megi 885hPa 125kts(65m/s) 2013海燕 Haiyan 895hPa 125kts(65m/s) 1991尤莉 Yuri 895hPa 120kts(60m/s) 1991露絲 Ruth 895hPa 115kts(60m/s) 1992蓋伊 Gay 900hPa 110kts(55m/s) 1998瑞伯 Zeb 900hPa 110kts(55m/s) 2012三巴 Sanba 900hPa 110kts(55m/s) CWB 台灣中央氣象局 2010梅姬 Megi 65m/s 2013海燕 Haiyan 63m/s 1993艾德 Ed 61m/s 1992蓋伊 Gay 60m/s 1992伊凡德 Yvette 60m/s 1991席斯 Seth 60m/s 1995奧斯卡 Oscar 60m/s 海燕 3個機構上榜!!!!!!! 梅姬 3個機構上榜!!!!!!! 蓋伊 3個機構上榜!!!!!!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.129.103.142
