摘　　要：气象数值预报模式是数值天气预报业务的重要基础,模式的研发改进需要在高性能计算环境中不断地开展模拟试验来检验评估预报效果。针对气象科学家手工编排批处理脚本开展数值模拟试验方式中存在的不便捷、耗时长、不可见、底层细节复杂、试验分析比对困难等问题,采用C/S架构,基于Python和工作流技术,设计实现了可视化界面交互“建模-计算-监控-分析-管理-共享”全流程集成应用的数值预报中试系统。应用结果表明,系统提升了模式研发试验效率和高性能计算机系统的易用性,在数值天气预报模式研发中试中发挥重要支撑作用,扩展性良好。Meteorological forecast numerical model is an important basis of numerical weather forecasting. The research and development of meteorological numerical model needs to continuously carry out simulation experiments in high-performance computing to test and evaluate the prediction effect. Aiming at the problems of inconvenient, time-consuming, invisible, complex details,difficult to analysis during meteorological scientists manually compile batch processing scripts to carry out numerical simulation experiments, this paper develops an interactive visual model test-bed system based on Python and workflow technology with client-server architecture, which provides the construction, simulation, monitoring, analysis, management and sharing for model experiment. The application results show that, the system improves the efficiency of model research and development and the usability of high-performance computer system, plays an important supporting role in the test-bed of numerical weather forecast model, and has good scalability.
