Abstract: Based on mean daily temperature and precipitation data from 1957 to 2000 in Shenyang area,the general characteristics and trends of temperature and precipitation variations were analyzed with linear trend analysis,Mann-Kendall break detector and Morlet wavelet transform method.Furthermore,their variation characteristics were discussed with the extreme temperature index and the extreme precipitation index.The results indicated that temperature showed a significant upward trend in Shenyang area during recent 44 years.And temperature variation had obviously abrupt change.The time of abrupt change was from 1981 to 1982.Precipitation showed a fluctuant downtrend,while intensity and frequency of extreme precipitation events were increasing since 1980s.
