In order to make full use of the accumulative huge climatic data,this paper presents a phase space analogy model of short range climatic forecast with multitime series.By using over 20 time series which are physically related with the climate changes of Yunnan Province,an yearly short range climate forecast model for Yunnan Province is established.The verification of precipitation and temperature forecasts for Yunnan Province shows that the accuracy of anomaly sign of model forecasts of the May precipitation and temperature from 1991-1998,and the June-August and yearly precipitation and temperature from 1990~1997 is 66.3% , 66.6%, and 63.1% ,72.3% ,71.3%,71.1% respectively.
