MM5微机模拟系统的简介和初步应用个例

本文将ＰＳＵ／ＮＣＡＲ ＭＭ５中尺度数值模式移植到微机上，利用改进的空军中尺度数值预报业务系统的前后处理技术，在微机（或工作站）上建立起了ＭＭ５中尺度模式模拟系统，介绍了该系统的各模块技术方案同时对南北方两次性质不同的暴雨个例进行了成功的模拟，并对一次梅雨锋暴雨进行了数值试验。实践表明，ＭＭ５中尺度模式诉建立十分成功，对天气形势、降水特别是暴雨等重大灾害性天气的模拟能力较强，模拟效果与实际基本一致

THE SUMMARY AND PRELMINARY APPLIED EXAMPLE OF MM5 SIMULATIVE SYSTEM ON COMPUTER

In this paper,the Penn State/NCAR MM5 mesoscale numerical model has been transplanted on computer,and the front-back job of the Air Force mesoscale numerical forecast professional system has been utilized. The simulative system of MM5 mesoscale model established on computer (or workstation),and also the the various model technological schemes are introduced. The two synoptic processes of heavy rain are simulated successfully,and the synoptic process of Mei -Yu front heavy rain was simulated. The simulation indicates:The erection of MM5 mesoscale model simulative system on computer is very success,the simulative capability on synoptic situation and precipitation is very powerful. The forecast results are found close to reality.
