摘要
利用常规气象观测资料、卫星云图对2015年6月29日发生在海南州区域性大到暴雨天气过程的影响天气系统、各物理量场、卫星云图进行分析。结果表明,副高外围西南暖湿气流与新疆槽中不断分裂冷空气在海南州交汇是导致此次区域性大到暴雨的主要原因,散度、垂直速度的高低空合理配置和高能、高湿是此次强降雨出现的动力、热力和水汽条件,中尺度对流云团和TBB<-53℃区域与大到暴雨具有较好的对应关系。
Based on conventional meteorological data and satellite image, a regional heavy-hard rainfall weather pro- cess in Hainan prefecture on June 29, 2015 was analyzed on influencing weather system, physical quantity field and satellite image. The results showed that intersection in Hainan prefecture between southwest warm and humid air around subtropical high and cold air split off from Xinjiang trough was the main cause of the regional heavy-hard rainfall. The divergence, reasonable configuration of vertical velocity in high-low altitude, high energy and high humidity were the dynamic, thermal and vapor conditions for the heavy-hard rainfall. The mesoscale cloud cluster and the region of TBB〈-53℃ were in good coincidence with the heavy-hard rainfall.
