摘　　要：研究选择自动气象站资料、NCEP再分析资料等相关观测资料诊断分析2022年台风“梅花”在吉林引发暴雨的天气过程。结果显示:在本次天气出现之前,“梅花”引导气流沿副热带高压后部西南方向急剧向北移动。吉林省大多区域西风带出现小槽波动,在其后方增加了一些冷空气,给“梅花”系统暖湿空气带来较大影响,为本次极端降水天气创造了环流形势。This paper selects the automatic weather station data,NCEP reanalysis data and other relevant observation data to diagnose and analyze the weather process of rainstorm caused by typhoon"Meihua"in Jilin in 2022.The results reveal:Before the occurrence of this weather event,the"Meihua"guided the airflow to move rapidly northward along the southwest direction behind the subtropical high pressure.Most areas of Jilin Province have experienced small trough fluctuations in the westerly belt,with some cold air added behind it,which has had a significant impact on the warm and humid air of the"Meihua"system,providing a good circulation situation for this extreme precipitation weather.
