地形的热力作用对湖北省暴雨的影响

THE EFFECT OF TOPOGRAPHIC HEATING ON HEAVY RAIN OVER HUBEI PROVINCE

本文利用湖北省1977-1986年6、7月份暴雨资料及1979—1986年恩施、宜昌、武汉三个站探空资料,研究了湖北省暴雨分布特征。结果表明,湖北省西部山区及青藏高原大地形的热力作用明显。本文用这种热力作用对湖北省的暴雨分布特征,提出一种可能的解释。

In this paper, features of heavy rain distribution over Hubei prov-ince are examined by using the heavy rain data for June and July1977--1986 and the sounding data for 1979--1986. The result showsthat the heating of the mountains in western Hubei province and themassive topography of the Qinghai Xizang Plateau is evident. This mayexplain the features of heavy rain distribution over Hubei province.
