簡單介紹幾個最完美的颱風.
海燕 2013 Hayian JTWC : 170kts JMA : 895hPa CWB : 63m/s
妮妲 2009 Nida JTWC : 155kts JMA : 905hPa CWB : 58m/s
蓋伊 1992 Gay JTWC : 160kts JMA : 900hPa CWB : 60m/s
這是一些國外評論對於海燕颱風的評價
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 by a huge, 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.
當中提到的是,海燕颱風登陸威力規模相當於. 1979年狄普颱風 1969年卡蜜兒颶風 1980年艾倫颶風的巔峰威力.
而提起的是海燕颱風的巔峰強度可能已超過1979年颱風之王狄普了. 而提到其實在20年前的兩個颱風規模可能已超越.
分別是1992蓋伊和1995安琪拉颱風.
德沃夏克分析法指出.這三個颱風(蓋伊 . 安琪拉. 海燕)規模都大於狄普颱風.
