摘要
利用闽北地面、高空气象探测站、加密区域自动站、雷达站资料,分析2013年3月19日发生在闽北的冰雹天气过程。此次冰雹天气过程是发生在高层中纬度低槽及南支槽,中低层低涡切变、低空西南急流的天气背景下。邵武高空探测资料表明,闽北上空低层大气逆温逆湿,中高层位势不稳定层结。3月19日闽北降雹的直接影响系统是超级单体雷暴与地面中尺度气旋相对应。
Using the date of surface, up- per air sounding stations in Northern Fu- jian, encrypted auto stations and radar stations, the hail occurred on March 19th, 2013 in North Fujian were analyzed. The hail weather process occurred under the background of the weather with up- per lower mid-latitude trough and south- ern trough, the low-level vortex shear, low-level southwest jet. The altitude ob- servation data of Shaowu showed that the lower atmosphere over the northern inversion inverse wet, high-level poten- tial unstable stratification. The direct im- pact system of northern falling hail in March 19th was supercell thunderstorm mesoscale cyclone correspond with the ground.
