Based on daily p recip itation data from 82 meteorological stations in Shandong Province from 1961 to 2004, the annual p recipitation and rainy dayswith different gradeswere calculated. The long - term variation and abrup t change characteristic of annual p recipitation and rainy dayswith different gradeswere analyzed by using accumulative anomaly and T - test, and the response of drought disaster to variation of p recip itation and rainy dayswere analyzed also. The results are as follows: The abrup t change of annual p recip itation, rainy days with moderate and above rainfall and drought disaster area occurred in the middle 1970 s, but rainy dayswith little and small rainfall aswell as total rainy days appeared in 1988 under the globalwarming background. After the abrup t change, the years appeared frequently with anomaly decrease of annual rainfall and rainy days, while the strong rainy days increased obviously. Precip itation and rainy dayswith different grades have a much closer negative correlation with drought disaster area. Abnormal decreases of annual precip itation and rainy days enlarged the drought area in Shandong Province.
