Climate simulations have suggested that a greenhouse-gas induced global warming would also lead to a moistening of the atmosphere and an intensification of the mean hydrological cycle. Such a change can contribute directly to changes in regional precipitation climate,so there is an ongoing interest in the possible relationship between temperature and extreme precipitation events(EPE). The relationship between summer temperature and extreme precipitation events was studied using Singular Value of Decomposition(SVD)method based on the daily precipitation and temperature data of the 610 meteorological stations in China and NCEP/NCAR reanalysis data from 1960 to 2009,the difference of their corresponding change in atmospheric circulation was also analyzed. Results show that there exists a significant correlation between EPE and temperature in China that a positive correlation in northwest and southern areas but a negative correlation in the northeast to southwestern areas. Abrupt summer temperature and EPE change both emerged around 1992,an abnormal continental cyclonic circulation whose center in Mongolia existed in 850hPa wind fields during pre-mutation(1960 1992),however, abnormal continental cyclonic circulation translated to anticyclonic circulation during later mutation(1993-2009). This abnormal cyclonic(anticyclonic)would strengthen(weaken)the cold air invasion southward,resulting in higher temperature of the later mutation. During pre-mutation,western and southern China were respectively influenced by abnormal western and southwestern water vapor transportation,water vapor was abnormal divergence and resulted in less EPE. However,northeast to southwest areas were affected by abnormal southwestern water vapor transportation,water vapor was abnormal convergence and leaded to more EPE. The situation was just opposite after mutation.
