摘要
超强台风"桑美"在浙江省温州市苍南县登陆,登陆时中心附近最大风力达17级,中心气压920hPa,是近50年来登陆我国大陆最强的台风。为了认识超强台风"桑美"强度突然增强的机制机理,气象工作者做了许多有意义的工作,如"桑美"的观测分析、数值模拟、强度突增原因探究等。文章对以往研究成果进行了简述,指出了目前在此方面研究存在的问题,如数值模拟台风强度突增的量值偏小,强度突增的机理没有新的明显突破,以及气候变暖对台风强度突增如何影响涉及较少等。
The super typhoon ＂Saomai＂ （No. 0608） landed at the coast of Cangnan County, Zhejiang Province on 10 August 2006, with the maximum wind force being up to 17 in the vicinity of its center and the central pressure being 920 hPa. It is the most powerful typhoon landed in China's Mainland since 1949. A great deal of researches reveal that the weak environmental vertical wind speed shear, high sea surface temperature （SST）, strong divergence at the upper level and remarkable vorticity near the center of Saomai, etc., play important roles in the rapidly intensifying process. Some researchers conducted invaluable work such as observational study, numerical simulation, and the causes of sudden intensity increase, etc. A review is made of the previous achievements, and the problems existing presently in this field are discussed.
