摘要
1 319号超强台风"天兔"登陆前后给梅州南部和东部带来了强降水,由于登陆前其环流与西南季风急流断裂,登陆后环流消失的非常快。低层强辐合抬升作用与强降水发生区域有良好的对应关系,在强降水发生时低层有大量的水汽辐合;另外,登陆前后"天兔"东侧暖湿水汽的输送有利于梅州暴雨的发生。由于登陆前大陆层结比较稳定,此次过程强对流天气并不明显。
The landing super typhoon No .1309“Usagi” had brought strong rainfall to the south and east of Meizhou .Its circulation disappeared very quickly after landing , because its circulation had broken with southwest monsoon torrent before the typhoon landing.Strong convergence uplift in lower had a good relationship with heavy precipitation areas , when heavy precipitation occurs , there is a lot of moisture convergence in lower; In addition, before and after the landfall of “ Usagi” , the warm water vapor transmission of its east side was conducive to rainstorm in Meizhou .The strong convective weather didn＆#39;t significantly in this process, because before landfall , there was stable continental stratification in mainland .
