Characteristics of Autumnal Typhoons over the Western North Pacific During 2002-2021
摘要
Abstract
Utilizing the annual typhoon data from the Shanghai Typhoon Institute of the China Meteorological Administration,this study examined the frequency,intensity,location,track,interannual variation,and intra-seasonal differences of typhoons over the Western North Pacific(WNP)during autumn(September to November)from 2002 to 2021,with a focus on those making landfall in China and the features of heavy precipitation and strong wind observed during typhoon landing processes.The findings reveal that of the 201 typhoons formed in the WNP during autumn in these twenty years,39 made landfall in China,representing 19.4％of the total and predominantly consisting of super typhoons(25.9％)and strong typhoons(21.9％).Before 2010,the number of autumnal typhoons was relatively low(9.4 per year),but the proportion of those making landfall in China was high(25.8％).After 2010,the annual number of typhoons increased(10.5 per year),but the proportion of those making landfall in China decreased(14.7％),with no significant overall trend.On average,about 1.95 typhoons made landfall in China each autumn,with super and strong typhoons together accounting for 61.5％of them.The interannual variation showed a pattern of rapid fluctuations before 2010,followed by a more stable and reduced number of landfalls after 2010.Autumnal typhoons that made landfall primarily affected Hainan,Guangdong,and Taiwan provinces,with the maximum observed wind speed and the maximum single-station rainfall generally exhibiting a linear correlation,implying that higher wind speeds correspond to heavier rainfall.However,the trends in both variables were not significant.In comparison,autumnal typhoons making landfall in Guangdong Province exhibited the highest maximum observed wind speed and the most intense single-station rainfall.关键词
