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.
