摘要
利用常规的气象观测资料、NCEP再分析资料等,对2023年第16号台风“三巴”在广西壮族自治区产生的强降雨过程进行综合分析。结果表明:高层的西南急流分流辐散抽吸作用,中高层的主要影响系统是副热带高压、短波槽东移引导冷空气南下,低层的东南急流提供水汽和能量,地面冷空气的侵入与台风倒槽形成锋区等都是有利于产生此次台风强降雨的环流形势。
Using conventional meteorological observation data,NCEP reanalysis data,etc.,a comprehensive analysis is conducted on the heavy rainfall process caused by Typhoon"Sanba"in Guangxi Zhuang Autonomous Region in 2023.The results indicate that the southwest jet stream in the upper layer has a divergent and suction effect,while the main influencing systems in the middle and upper layers are the subtropical high pressure and the eastward movement of the shortwave trough,which guides cold air southward.The southeast jet stream in the lower layer provides water vapor and energy,and the intrusion of cold air on the ground and the formation of a front area in the typhoon trough are all conducive to the circulation situation of this heavy rainfall caused by the typhoon.
