中文摘要: 在降水时空变化研究的基础上,完成辖区降水区划;用计算机识别T213风场中槽线、切变线等影响系统,并按其相对于预报站方位,确定对其影响强度指数,组合预报因子,建立判别方程,制作分县0~12小时、12~24小时降水分级预报。经检验,系统对降水落区有较强预报能力。
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.
