Abstract:
Based on the Xband phasedarray Doppler radar, Sband dualpolarization radar (SPOL) and conventional surface and upperair data, we analyzed the characteristics of a severe convective process in South China that happened on 3 June 2016. The results are summarized as follows. (1) The intensity, velocity and phase distribution of supercells can be observed by Doppler parameters and dualpolarization parameters of SPOL. The formation of hook echo is affected by the influx and outflow of supercells. (2) XPAR can obtain spatiotemporal resolution much higher than observation data of SPOL, which can make up for the serious shortage of elevation layer. The complete vertical structure of super cells can be observed and the shortterm evolution of supercells can be more accurately described. (3) Hypercubes near the hook echo brought cooling temperature, strong winds and heavy precipitation to the surface, and the areas with the supercells passing through had significant drop in temperature and strong winds. The results show that phasedarray radar and dualpolarization radar are more helpful to understand the evolution of supercells.
