摘要
经对郑州市1990～2000年气象资料分析,概括出短时暴雨、瞬时雷雨大风、冰雹等3种强对流天气出现的气候规律、天气形势、物理量场演变特征、单站气象要素变化规律等.在此基础上,建立了3种对流性天气的预报模型、预报指标和相应的预报方程,构成郑州市强对流天气短期预报系统.该系统根据每天08时实时资料,自动完成天气分型、物理量计算、预报指标计算和预报方程的判别,输出预报结论.
Through analyzed meteorological data from 1990 to 2000 in Zhengzhou, it was summed up that the rain and gale, and hail etc. Based on this, we have established forecasting model, forecasting index and corresponding forecasting equation of the three severe convective weather, which formed short - range forecasting system of se- vere convective weather in Zhengzhou. Based on the real time data at 8 every day the system classifiesweather types ,calculates physical quantity and forecasting index and judges forecasting equation automatically , and eventually outputs forecasting conclusion.
