| Abstract: | Based on conventional meteorological observations, NCEP reanalysis and radar observations, a hail process that happened in northern Guangdong in March 2013 was studied. The result is presented as follows. The hail was formed due to the joint effect of jet streams at the upper and low level, a shear, a convergence line at the surface and weak eoht air. Clouds of potential hails can well be identified by products of basic reflectivity of the radar, VIL and VWP. |
