Design and Implementation of Regional Numerical Weather Prediction Operation Management System

China Meteorological Administration (CMA) and regional centers have developed their own Numerical Weather Prediction (NWP) operation systems, which work process is complicated, including data preprocessing, analysis, model forecast, post-processing, visualization and other aspects but were lack of a unified management and monitoring. Based on the demands of NWP operation systems, this article gives a detailed description of research and development of the numerical weather prediction operation management system based on work flow. This system has achieved full operational management and monitoring the NWP operation systems and HPC systems of national and regional center, through interaction visual interface directly display the working process of numerical weather prediction models, and when there is a fault, timely provision of graphics and SMS messages warning function. This system has greatly improved work efficiency, provided guarantee for the stability of numerical weather forecast.
