In order to reveal the characteristics of precipitation variation in Chuzhou during 1952 to 2012 ,the variation characteristics of annual , seasonal , monthly precipitation in Chuzhou city were analyzed based on the data of its precipitation .The results showed that annual precipitation change is obvious and precipitation rate is 10 .232 mm/10a in Chuzhou .T he precipitation decrease trend in spring is evident , while the precipitation increase trend in summer and winter is more obvious . For the precipitation distribution of four seasons ,the precipitation in spring and summer is more than that in autumn and winter .Monthly rainfall distribution is very uneven and the amount of precipitation in July is the most and that in December is the least . T he number of days of annual precipitation overall showed a trend of gradual decrease and climate tendency rate is -6 .628d/10a .The overall average rainfall intensity in four seasons is increased ,and rainy days have a decreasing trend overall .In four seasons ,spring and autumn is given priority to with moderate rain ,summer with rainstorm ,winter with light rain and moderate rain .In twelve months ,January and December is given priority to with light rain ,February ,March ,April ,October and November with moderate rain ,May with heavy rain , and June ,July ,August and September with intense fall .
