Abstract: In order to study the spatial and temporal distribution characteristic of summer precipitation and air temperature in northeast China, based on the 160 stations monthly precipitation and temperature observations in national climatic data center from 1951 to 2010, we used empirical orthogonal function analysis and wavelet analysis method to discuss it. The results show that the summer precipitation in northeast China mainly exist the same anomaly in whole area, opposite anomalies in the south and north or in the east and west or in middle area , the air temperature in northeast China mainly exist the same anomaly in whole area, opposite anomaly in the south and north, and there is significant changes in volatility. Summer precipitation and air temperature in northeast China exist significantly different time scales oscillation period, the precipitation has 29a primary period, the temperature has 28a primary period.
