同一大尺度天气条件下的两地明显降水差异成因分析

An Analysis of precipitation difference in evidence between two section of the same big-scale circumfluence background

通过对地域毗邻的广西、广东两省2004年春季一次降水个例的综合分析,结果表明,两广锋前中尺度流场、锋面坡度的不同,以及两地明显的水汽和垂直运动条件的差别,是造成这次两广明显降水差异的主要原因所在。所得结果可对今后预报提供一些启示和参考。

The precipitation case in spring between Guangxi and Guangdong which section abut is synthetically analyzed. The result shows that the main reasons which cause precipitation difference in evidence are the dissimilitude of middle-scale circumfluence and front gradient, the distinction condition in evidence of vapour and perpendicularity sport. The results about the cause of this precipitation difference in evidence will benefit the operational prediction.
