1949-2020年黄渤海区域台风特征分析
Typhoon Characteristics in the Huanghai and Bohai Sea Region During 1949-2020
摘要
Abstract
Utilizing best-track data of typhoon provided by the China Meteorological Administration(CMA),this paper conducts an analysis of the climatic characteristics of typhoons(TCs)having entered the Huanghai and Bohai Sea Region(30°-50°N,110°-130°E)from 1949 to 2020.The results indicate that,on average,4.3 TCs enter the Huanghai and Bohai Sea(HBS)Region annually,showing a signifi-cant increasing trend in the percentage of HBS TCs in the western North Pacific typhoons(WNP TCs).HBS TCs are active between April and November.Since the 1990s,there has been an increase in HBS TCs activity during autumn.The primary genesis region for HBS TCs is located between 5°N to 30°N and 120°E to 160°E.Since the 1950s,it has been continuously shifting westward.Prior to the 1980s,there was a gradual northward trend,which was followed by a southward trend accompanied by the phenomenon of"autumn expansion"after the 1990s.Most HBS TCs enter the HBS via distant sea tracks,traveling a con-siderable distance from land.Then,there are HBS TCs that change direction or move northward during their offshore or landing activities.The other HBS TCs dissipate after landing,continue moving westward at high latitudes,or turn westward within the Yellow Sea.51.8％of HBS TCs undergo extratropical tran-sition,and among them,28.6％strengthen after the transition.The intensification following extratropical transition mainly occurs from June to October,peaking in August and September.The central and south-ern regions of East China and the southern part of the Sea of Japan are the two main areas where such in-tensification is concentrated.关键词
