| Abstract: | 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. |
