| 摘 要： | 以江苏省62个气象站1961-2005年降水资料为基础,系统分析了近45年来江苏省降水变化趋势.结果表明:1961-2005年江苏省年降水量无显著变化趋势,秋季降水量呈显著下降趋势,冬季降水量呈显著上升趋势.全省年降水日数呈略有下降趋势,以小于10mm的降水日数下降尤为明显.夏季极端强降水总量、极端强降水事件频率为增加趋势,秋季极端强降水事件强度为下降趋势. |

| Abstract: | Based on the observational data of 62 meteorological stations from 1961 to 2005, the spatial and temporal distributions and their trends for precipitation in Jiangs u Province are investigated. The conclusion can be drawn as follows: Although th e annual precipitation in Jiangsu has no significant change trend, the autumn pr ecipitation has an obvious decrease trend, but winter precipitation has a signif icant increase t rend. The annual precipitation days in Jiangsu have slightly decreased, which ar e mainly caused by the decrease of the annual days of the light rain, i.e. the d aily rainfall is less than 10.0mm. The extreme total rainfall and its frequency in summer appear a significant increase trend and the extreme precipitation inte nsity in autumn takes on a decrease trend. |
