摘要
利用观测数据、卫星云图、雷达资料,分析了2018年4月19—20日出现在甘肃临夏地区的一次强对流天气过程。此次过程出现了冰雹及短时强降水,并造成了灾害。结果表明,低涡东移南压、从甘肃河西到甘南州的大范围中层切变、充足的水汽条件及前期较高的基础温度是触发本次强对流的主要原因。
Using observational data,satellite imagery and radar data,a strong convective weather process occurred in Linxia area in April 19-20,2018 was analyzed.During this process,hailstorms and short-term heavy rainfall occurred,which caused disasters at the same time.The results showed that the main reasons for this strong convection were as follows:low vortex eastward transfer south pressure,large-scale mid-range shear from the western Yellow River to Gannan Prefecture in Gansu Province,adequate water vapor conditions and higher initial temperature.
