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 December 2017, 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.
