沙尘暴数值预报模式CUACE-Dust的并行与优化

Parallel and optimization works for sand-dust numerical forecasting model

介绍了中国气象局成分中心发展的耦合于MM5的沙尘暴数值预报模式CUACE-Dust并行化及优化工作,该系统能减少运行时间,提高并行效率,确保了高分辨率业务预报的及时性.该系统目前已经通过了中国气象局业务化评估,用于气象局沙尘暴数值业务预报.同时,为了使用的便利性,通过编写脚本文件使多个程序实现了自动流程化运行.最后给出了一些测试结果,表明了工作的有效性.

The parallel scheme and optimization works for a sand-dust numerical model coupled with PSU/NCAR Mesoscale Model(MM5)—CUACE-Dust(China unified atmosphere chemistry system-dust) is introduced.These works reduce the run-time and increase the efficiency which is most important for real-time and high resolution forecasting.Based on CUACE-Dust,a numerical model forecasting system is established in northeast Asian,and is applied to China meteorological administration(CMA) for operational prediction of sand and dust storm.Meanwhile,shell scripts are designed for auto stream running of several programs to promote the user′s convenience.Some testing results are given out at last to indicate the significance of our work.
