Based on historical data (19602015)on daily temperature and precipitation obtained from 17 meteorological stations in Anhui Province and 9 meteorological stations around Anhui Province,we made a comprehensive investigation of the change characteristics of the climate using climate tendency method, Mann-Kendall test method,moving t-test and cross wavelet method,and the relationship between the ENSO and climate factors was discussed.The results showed that,firstly,annual average temperature rose obviously, maximum variation was 0.3℃/10 ain spring;precipitation increased slightly,but the seasonal variation was larger,especially in summer and winter;in spring,summer,autumn and winter,the rise of the annual temperature was significant,the large rise of monthly temperature occurred in May,June,October and February, respectively,while the precipitation change occurred in April,August,September and January,respectively; secondly,the temperature in the central region was higher than that in the south and the north,and the low temperature zone was found in the Huangshan area;the temperature changes in all areas in spring were significant,and the summer changes were not obvious;the precipitation decreased with the increase of latitude,and the Huangshan Mountain area was the region with the high precipitation;and the trend of winter and summer was obvious in different regions;thirdly,abrupt change of average annual temperature occurred in 1994,significant rise in temperature was 0.8℃ after abrupt change;the abrupt changes occurred in the three seasons except the summer,the average spring temperature change was most obvious and significantly increased by 1.1℃after abrupt change.The abrupt change of precipitation occurred in the spring and autumn period,no abrupt changes were found in the summer and winter;finally,the temperature,precipitation and ENSO cycle had a significant cycle of 3~5 years,mainly concentrated in the 1960 s,1980 sand 1990 s,and the annual precipitation cycle relatively lagged compared with the average annual temperature cycle.
