Abstract: Accordance with the National Meteorological Center, T213, T639 global model, and Chengdu Regional Center for real-time operation of the AREM, GRAPES, and mesoscale numerical model MM5 forecast results, in 2008 carried out from May to September daily precipitation and 2m temperature testing.The results are as follows:(1) the forecast temperature in Kunming, Nanjing, Guangzhou, Changsha, Beijing and Zhengzhou is better than Wenjiang, Lanzhou and Lasa stations, the temperature in Lasa station has the greatest deviation to observation, the temperature prediction by models in central and southern areas of china is better than in the western region. (2) Moderate rain and higher order of magnitude precipitation score values of models higher than that of the western areas, Kunming which is one of the four cities in western station has the highest TS score value, reflecting models have weak prediction capabilities to China's western city.
