基于ECFLOW实现华中区域快速更新同化预报业务流程

Implementation of ECFLOW-Based Operational Process of Rapid Refresh,Assimilation and Prediction for Central China

为了进一步满足华中区域对高时空分辨率数值预报产品的业务需求,为短临预报和精细化格点预报提供技术支撑,华中区域快速更新同化预报模式系统于2015年7月完成系统搭建并开始业务试运行,2017年12月又根据业务需要完成了系统结构的调整。由于该系统具有流程复杂,步骤繁多的特点,为了使调度监控更加直观,故障定位更加准确,系统维护更加高效,运用ECFLOW技术对整个预报系统进行了流程化调度开发,设计并实现了华中区域快速更新同化预报业务流程监控系统。该系统图形界面美观友好,流程结构清晰明了,故障定位准确且处理操作简单,可大幅提升业务模式运行监控及维护的工作效率。

In order to satisfy the strong operational demand for high space-time resolution numerical forecast products in the Central China area,the high-resolution and rapid-refresh numerical weather prediction model system for Central China was designed and have operated since July 2015.In December2017,the structural adjustment of this model system was conducted according to the operational needs.As the system has the characteristics of complex processes and numerous steps,a monitoring system,which fully considers the relationship between various model processes and integrates all processes as a whole,is designed and implemented based on ECFLOW technology.The process monitoring system has a beautiful and friendly graphical interface and clear flow structure that can make the operation simple and fault location accurate,which can improve greatly the working efficiency of operation,monitoring,and maintenance.
