Abstract:This article reviews the three decade development of the typhoon numerical forecast operational system in the National Meteorological Centre (NMC) of China Meteorological Administration since the beginning of the Eighth Five Year Plan, including its first generation typhoon track numerical prediction system using regional model, a typhoon track numerical prediction system developed on the basis of the global spectral model, and the global and regional tropical cyclone (TC) forecast system independently developed by the China Meteorological Administration. It summarizes the key technologies and forecast performance of these systems, with a focus on the main technical achievements of GRAPES_TYM. It also puts forward some views on the development of the national typhoon numerical prediction system in the next five years.
