近20年影响盐城的台风特征分析
Analysis of Typhoon Characteristics Affecting Yancheng in the Past 20 Years

本文利用风险普查台风灾害数据和2000~2020年影响盐城地区的台风实测资料，从影响频次、影响时间、移动路径等方面统计21年间影响盐城地区的台风气候特征。同时对比分析不同路径以及不同天气形势下，台风对盐城地区所造成的灾害性天气即台风暴雨和大风，为以后盐城地区台风天气预报和防灾减灾提供一些参考。结果表明，不同路径类型的台风对盐城地区降水的空间分布不同，产生台风暴雨最多的为登陆北上型路径；造成盐城市台风暴雨的主要环流形势是受西风带高空槽、台风倒槽以及副高西侧暖湿气流共同影响下形成。
This paper uses the typhoon disaster data of the risk census and the measured data of typhoons af-fecting the Yancheng area from 2000 to 2020 to analyze the climate characteristics of typhoons affecting the Yancheng area in 21 years from the aspects of impact frequency, impact time, and moving path. At the same time, we compare and analyze the disastrous weather caused by typhoons in Yancheng area under different paths and different weather conditions, that is, typhoon torrential rain and strong winds, so as to provide some reference for typhoon weather forecast and disaster prevention and mitigation in Yancheng area in the future. The results show that typhoons with different track types have different spatial distributions of precipitation in Yancheng area, and the track that produces the most typhoon rainstorm is the northbound track, formed under the combined influence of warm and humid airflow on the west side.
