An Improved Method MOS Forecast Based on Circulation Characteristics

QI Ming\|hui,XIAO Zi\|niu,YAN Hong\|ming(Meteorological Institute of Yunnan, Kunming 650034, China)  
A new method of forming MOS(Model Output Statistic)forecast factors to improved prediction accuracy was given in this paper. The result show that the method can significantly improve the MOS forecast skill for precipitation and temperature of 32 stations in Yunnan. But the MOS forecasts for precipitation are more skillful than that for temperature in Yunnan. At the same time, the test display prediction accuracy of MOS is sensitive to the forecast factor select. And considering circulation background and making a optimal forecast factors is very important to improve the performance of MOS forecast.
