Abstract:
By using canonical correlation method,the forecasting experiment of the rainfall during the flood season in Yunan Province is performed.The mean circulation field of 500hPa,its height anomalies in some key regions and sunspot number from January to April during 1960—1997 are selected as the common influence factors,and the canonical correlation models,which include the whole factors and the first ten factors,are built and used to predict the rainfall during the flood season.The results show that the model with the first ten canonical variables in better than that with the whole factors for 1998 and 1999,respectively.The accuracy of prediction in 2000 is 10/16.
