【摘要】 华北地区区域性暴雨综合预报技术是以ＨＬＡＦＳ数值降水预报产品为基础，以物理量诊断为主要依据，综合使用红外卫星云图、常规气象资料和国内外数值预报产品等众多信息逐步订正，以人机结合方式制作华北地区区域性暴雨预报的技术。实验表明，该技术对华北暴雨有较好的判断和预报能力，其主要特点是：基本上模拟预报员的预报思维和业务流程制作暴雨预报；系统分段执行，透明度大，便于改进，也有利于预报员了解暴雨发生发展的机理和规律．更多还原

【Abstract】 The comprehensive technique is a man and computer interactive system for forecasting regional torrential rain in Huabei area , which is based on numerical precipitation prediction products of HLAFS , judged by diagnosis of meteorological elements and corrected step by step by using in- frared satellite images , conventional meteorological data and NWP both domestic and abroad . Experimental study shows that this technique has a remarkable ability to identify and forecast tor- rential rain in Huabei Area. The main characteristics of the system are the following , first , it basi- cally simulates the forecaster ’ s thinking and work procedure to forecast torrential rain ; second , as working step bv step , the system has higher transparency and is convenient for further improve- ment and for forecaster to know the mechanism and law of torrential rain onset and development .更多还原
