Analysis of temporal and spatial characteristics for temperature and precipitation in summer of China
我国夏季气温、降水场的时空特征分析

The characteristics of temperature and precipitation in summer over China during the period of 1951 - 1985 are investigated by using the method of principal component analysis and rotated principal component analysis. It is found that the dominant components associated with the corresponding spatial patterns for temperature and precipitation have the period of 2 - 3y in temporal variation. The variability in the spatial patterns for temperature is more stable than that of precipitation in temporal variation. The significant negative correlation between temperature and precipitation is found in most part of China.
