摘要:
利用micaps常规观测资料对2015年5月14-23日广西一次连续性暴雨天气过程进行诊断分析,结果表明:(1)东亚大槽引导地面冷空气南下不断影响广西,副热带高压西北侧的西南气流有利于水汽和不稳定能量的补充;华南地区一直处于两高之间的低槽区,广西持续受槽前正涡度平流的影响。200hPa南亚高压东北部的分流区为暴雨的发生创造了良好的高空辐散条件。(2)活跃的西南季风急流和中低纬度中尺度系统的配置是持续暴雨天气产生的有利背景条件。(3)水汽条件和动力条件的演变具有在桂西北获得发展后向东扩展的演变特征对暴雨预报有很好的指导意义
Abstract:
Based on conventional observation data of MICAPS, a consecutive rainstorm process appearing in May 2015 of Guangxi was analyzed. The results show that:(1) East Asia deep trough guides ground cold waves constantly influencing Guangxi, southwest airflow of northwest edge of subtropical high is advantageous to the supplement of water vapor and instability energy. The south China area has been in the low trough area between two high troughs, Guangxi continuously was affected by positive vortices advection. Northeast diverging area of 200 hPa South Asia high created good upper divergence for the occurrence of heavy rain. (2) Configuration of active southwest monsoon rapids and low-latitude mesoscale system is good background of thunderstorms and consecutive heavy rain weather. (3) The evolution characteristic of moisture conditions the evolution of the dynamic conditions developing in northwest Guangxi and then expanding eastward has very good guidance for rainstorm forecast.
