摘要
利用常规观测、数值预报产品及自动站等资料对2020年3月15—16日青海一次大到暴雪天气过程成因进行分析。结果表明,此次降雪天气过程属于乌山槽底分裂短波槽携带冷空气下滑同南支槽北上共同造成的降雪类型。过程期间青海地区处于等值线密集区,青南地区处于高能舌中,柴达木盆地附近形成假相当位温槽,有利于位势不稳定的建立,为此次强降水过程提供不稳定条件。
Based on the data of routine observation,numerical prediction products and automatic stations,the causes of a heavy snowstorm in Qinghai Province from March 15 to 16,2020 were analyzed.The results showed that the snowfall process belonged to the type of snowfall caused by the cold air falling from the split short wave trough at the bottom of Wushan trough and the north of the south branch trough.During the process,Qinghai was in the isoline intensive area,and south Qinghai was in the high energy tongue.The formation of pseudo equivalent potential temperature trough near Qaidam Basin was conducive to the establishment of potential instability,which provided unstable conditions for the next heavy rainfall process.
