摘要
为更好地研究七台河市寒潮天气过程的环流形势,为预报服务提供参考,选取秋季一场较强寒潮过程和降温前期形势进行分析,该过程具有典型的环流背景,包括东亚倒Ω流型的建立、乌山阻塞高压的建立与崩溃、横槽转竖等特征,得出寒潮暴发的天气学成因。
In order to better study the circulation situation of the cold wave weather process in Qitaihe City,and provide reference for the forecast service,a strong cold wave process in autumn and the pre-cooling situation were selected for analysis,which had typical circulation background,including the establishment of East Asian inverted Ωflow pattern,the establishment and collapse of the Wushan blocking high pressure,and the turning of the horizontal trough,etc.,to obtain the meteorological causes of the cold wave outbreak.
