Abstract:
Based on the analysis of spatial and temporal charactristics, the division of rainfall regions is conducted in Jiaozuo, Henan Province.The precipitation systems(trough line,shear line,etc.) are recognized with computer in T213’s wind forecasting fields, and the systems strength index of 7 forecasting stations are confirmed on their opposite location. By combining predictors, the judging equations are established for giving the rainfall scale in 0—12 hours and 12—24 hours periods.The results show that the method is capable of forecasting rainfall regions.
