Abstract

Abstract:

Using dual-polarization radar data from March to September from 2016 to 2021, the spatiotemporal variation characteristics of convective cloud systems in the mountainous area of central Hainan province were analyzed.The results show that there are 951 cases of convective cloud systems in the mountainous area of central Hainan, accounting for 21.55% of the total number of convective cloud systems in the whole islands of Hainan province during the same period (4412).Among them, the warming high-pressure ridge and the South China Sea trough are relatively easy to cause convective cloud systems in the mountainous area of central Hainan province, 207 times and 189 times, respectively.March and April are the two months with the highest proportion of convective cloud systems in the mountains area of central Hainan province, both accounting for more than 30%.The main period of convective cloud systems in the mountainous area of central Hainan province is from 13:00 to 17:00, with 777 occurrences.The space of the convective cloud system in the central mountainous area mostly moves to the northeast and southeast, and the guiding air is mainly southwest and northwest.The most frequent cloud system moving velocity is 6~10 km·h^-1 and 11~15 km·h^-1, which are 306 times and 229 times respectively.The moving distance of the cloud systems is mainly concentrated in the 11~15 km and 16~20 km intervals, which are 26.5% and 19.2%, respectively.The typical case of convective cloud systems in the mountainous area shows an obvious "ZDR column" phenomenon at the early stage of the cloud systems, and the dual polarization phase relation value is low in the middle and low layers.There is a strong radar echo overhang in the middle of the cloud system.
