2022年西北太平洋和南海台风活动概述

Overview of typhoon activities over western North Pacific and the South China Sea in 2022

利用中国气象局热带气旋最佳路径等资料,对2022年西北太平洋及南海台风活动的主要特征和影响我国台风的路径、强度及风雨影响进行分析和回顾。结果表明:2022年西北太平洋及南海台风生成个数与常年持平,台风总体强度偏弱,生成源地显著偏北;登陆台风个数偏少,登陆强度偏弱;有3个台风集中在广东西部登陆,另外强台风“梅花”是1949年以来首个4次登陆不同省份的台风。全年多台风事件频发,共存的台风共计有11组,历史罕见。2022年台风灾害影响较轻,夏台风偏少,秋台风活跃。

Using the data such as the CMA(China Meteorological Administration)Tropical Cyclone Best Track Dataset,an analysis and review are conducted on the main characteristics of the typhoon activities in western North Pacific and the South China Sea in 2022,focusing on the tracks,intensities,and wind and rainfall impacts of the typhoons on China.The results are as follows.In 2022,the number of typhoons generated in western North Pacific and the South China Sea is consistent with the annual average,and the overall intensity of typhoons is relatively weak with significant northward shifts in their genesis regions.The number of landfalling typhoons is less,and their intensities upon landfall are comparatively weak.Three typhoons make landfall concentratedly in the western part of Guangdong,and the severe typhoon Muifa has become the first to make landfall in 4 different provinces since 1949.The multiple typhoon coexisting scenarios occur throughout the year with a total of 11 typhoon groups,which is a rare phenomenon.The typhoon-related disasters in 2022 exert relatively mild impacts,the summer of 2022 experiences less typhoons,while the autumn is characterized by intense typhoon activities.
