| 摘 要： | 选用1959~2007年上海市龙华站降水、气温资料及青浦、嘉定降水资料,运用累积曲线、距平统计和相对偏差对比等方法对上海地区降水量进行统计分析,并对上海市城区、郊区降水的时空特征进行对比。结果表明,上海城市气温和降水变化基本一致,城区、郊区降水存在显著差异,雨岛效应主要集中于5~10月汛期,21世纪城区、郊区降水差距有减小趋势。

| Abstract: | On the basis of the precipitation database collected from Longhua,Qingpu,Jiading stations during 1959~2007,with the methods of cumulative curves,statistics and relative deviation anomaly contrast,the precipitation and its temporal and spatial characteristics were compared and analysed.The results show that the temperature and precipitation were changing basically the same way,significant precipitation differences exist between urban and suburb;rain island effect in Shanghai mainly in May to October,the urba... |
