1949-2021年登陆我国热带气旋历史规律研究
A study on the characteristics of tropical cyclones landing in China from 1949 to 2021
摘要
Abstract
Based on the best tropical cyclone track data from the China Meteorological Administration from 1949 to 2021,tropical cyclones that landed in China are selected according to the rules in this article.The characteristics and variations of the number,intensity,and time of tropical cyclones landing in China are analyzed and studied with specific focus on the variations of tropical cyclones landing in different coastal areas.The results show that from 1949 to 2021,the number of tropical cyclones landing in China shows a slight decreasing trend with obvious peaks and troughs,which maintains at a low level after 2018.The intensity of tropical cyclones at landing time concentrates on strong tropical storms and typhoons,and the landing months mainly limits in July-September.There is a decreasing/increasing trend in the number of low-intensity/high-intensity landing tropical cyclones,indicating that global warming and tropical expansion may lead to more and more high-intensity landing tropical cyclones in China.The locations of tropical cyclones landing in China show a slight southward movement without significant change in longitude,which is inconsistent with previous researches partly due to different data sources and time spans.The provinces with highest number of landing tropical cyclone are Guangdong,followed by Taiwan,Hainan,and Fujian.Taiwan has the highest proportion of high-intensity landing tropical cyclones,followed by Zhejiang,Fujian,Guangdong,and Hainan.The annual numbers of tropical cyclone landing in Guangdong and Taiwan show a decreasing trend,while those in Zhejiang and Fujian show an increasing trend.关键词
