摘要

本文采用珠江三角洲１９７６～１９８３年３～８月各站逐日雨量资料和广州站探空资料，用相关对比度分析方法，研究了本地区暴雨的环境条件。结果表明，初春和夏季在对流层深厚气层内，春夏过渡季节在对流层中下层，气压低、相对湿度大、水汽含量高和风速大是暴雨形成的基本条件。春季暴雨多与层结不稳定或对流性不稳定有关，夏季暴雨倾向于在层结稳定和对流性稳定或中性的条件下发生，对流层负风速切变有利于夏季暴雨形成。

Abstract

By using the daily data of rainfall amount in Zhujiang Delta and Guangzhou’ s sound-ing from March to August of 1976￣ 1983

the favorable and unfavorable environmental condi-tions of genesis of hard rain in Zhujiang Delta

which is situated in the tropics

are analysed.And the conditions obtained are compared with those in the extratropics. The conclusion in this pa-per could be helpful to the forecasting and understanding of hard rain in the area.
