摘要
该文介绍了区域暴雨增强数值预报业务系统的设计思想、主体结构及主要的关键技术，并总结了该系统业务试验的情况和效果。该系统以ＹＨ模式为基础，对其从坐标系、水平和垂直分辨率及物理过程等方面进行了改进，并结合实时资料处理系统、图形处理等形成了一个比较完整的数值预报业务体系。该系统的特点是使用Ｔ６３预报产品作为初值客观分析的猜测场，引入卫星云图资料、三维嵌套和并行计算技术，在多ＣＰＵ工作站和微机上实现了并行计算的数值预报业务。该系统已成功地进行了业务试运行。
The schemes,structure and key techniques of a enhanced numerical prediction operational system of regional heavy rain is introduced in this paper. The operational test and forecat performance are summarized in the paper. Based on YH model developed by Yan Hong et al,the system is improved in coordinate system, horizontal and vertical resolutions,physical processes and etc. The system is also characterized by using 3-D nesting technique between the model and T63L16 and parallel processing. The parallel processing of numerical prediction operational system is realized both in multi-CPU workstation and micro-computer. The operational test of the system has successfully achieved some effects.
