| 摘 要： | 广州是中国的暴雨多发城市,气候、天气系统、地理位置及地形是形成暴雨的主要因素.文章选取了广州市区、番禺、花都、增城、从化五个站点1985~2004年的暴雨资料,分析了近20年广州地区暴雨的时空规律,表明:暴雨具有发生频率高、强度大、分布集中的特征;暴雨频次、等级、雨量的基本特征具有正相关关系;五个站点中从化和增城的次数和强度相对突出,近20年来频率有明显增加的趋势.

| Abstract: | Guangzhou is the rainstorm pilosity city of China. The climate,weather system,geographical position and topography are main factors of the rainstorm.This paper extracts the rainstorm materials of five sites about Guangzhou urban area,Panyu,Huadu,Zengcheng and Conghua from 1985 to 2004.The space-time law of the past 20 years has been analysed.We indicate: rainstorm is frequent in high intensity and centralized in distribution.And the frequency grade and rainfall of rainstorm have a positive correlation.Conghua and Zengcheng are relatively outstanding in frequency and intensity at these five sites,and the frequency has had an obvious increasing tendency in the past 20 years. |
