摘　　要：应用先进的中尺度数值模式和业务平台,集成并行计算、可视化工具等软件,为我国地方、军队等气象业务提供一套切实可行的精细化天气预报系统。经检验系统的24 h晴雨预报准确率可以达80%以上,对暴雨的预报也有一定的参考价值。应用在海浪预报中,可以显著提高预报准确率。系统的设计有利于基层台站的实际业务应用和模式本地化处理,无论从硬件要求,还是软件的应用和预报水平检验,系统都适合省地台站开展精细化预报业务。A fine forecasting system was developed for provincial/prefectural-level meteorological offices and military weather forecasting agencies in China by adopting the advanced mesoscale models and operational platform, and assembling the software of the parallel computing and visualizing tools. The accuracy of the 24-hour fine-orrainy forecast is up to over 80 % and the torrential rain forecast is quite helpful. The system was also used to forecast sea waves with the results improved obviously. The system is well suitable for the operational application at provincial/prefecturallevel meteorological offices and the localization of forecasting models in either economical or forecast quality aspect.
