Abstract:
The diagnostic analysis of physical variables for area rainstorm from June to August in Henan Province was conducted and the dynamic model was given by using numerical forecast product of T63.The shortrange automatic forecasting system of rainstorm with divided areas was developed by the artificial intelligence,and by using the numerical forecast product data of T63(T42),two kinds of selecting regression independent variable method were used to establish the integrated discriminate forecasting in Henan province,one of two kinds is the stepwise regression analysis,the other is the least standard of the sum of error square.The trial results of the operational forecast from July to August in 1995 and 1996 was reviewed.
