Abstract:
Using the summer (June to August) temperature data from 1951 to 2008, the temporal and spatial distribution features are studied by applying the methods of EOF， REOF， MannKendall trend test, etc. The results show that: (1) the eastern region of China in summer can be divided into three main types of spatial characteristic fields: uniform type, reverse northsouth type, positivenegativepositive type. (2) The summer mean temperature field can be divided into seven major regions: North China, Jianghuai region, Southeast China, South China, Southwest China, Northwest China, Northeast China. (3) Summer temperature in the eastern region of China showed an increasing trend after the first drop. (4) Summer temperature in the entire eastern region had a sudden change in 1997, with the temperature going up, and there were sudden changes in different years in each subregions.
