中尺度数值预报模式(MM5)在海面风场预报中的应用

本文简要介绍了在工作站上运行有限区域海面风场数值预报业务化系统的情况。该系统以MM5V3作为主要框架，选定了积云对流和边界层参数化方案，准备了三种侧边界方案，以确保有限区域海面风场数值预报业务化的运行。半年多的准业务运行表明，系统运行稳定，海面风场预报效果较好，除能直接给有关业务单位参考外，还提供给有关海洋数值预报模式使用。

THE APPLICATION OF MM5 MODEL TO PREDICT SEA SURFACE WIND FIELD

An advanced operational numerical prediction system has been developed to predict limited region sea surface wind field on the work station. The system has continued to work with the MM5's physics packages and run-time configurations to try to find the most accurate modeling parameterizations and conditions which the model is run. The physics packages, which determine how the model treats processes such as cumulus convective parameterization, boundary-layer structure, and lateral boundary conditions, as cumulus well as the initial run-time configuration, are all definable by NMEFC modelers, who try to ensure that the most favorable configurations are used for model forecasts. Real time operations have indicated that the system works stably, the predicting result is credible.
