Abstract:
Quantitative precipitation forecast (QPF) is the traditional and critical forecasting operation of National Meteorological Centre (NMC). With the rapid development of society and economy and its increasing demand in the fineness of various meteorological products, developing the fine gridded QPF has become the primary task of NMC. A fine gridded QPF product system with a spatial resolution of 5 km and 1 h 〖JP2〗interval for 3 d lead time and 3 h interval for 3-10 d lead time has been built, which covers rain, sleet, freezing rain, snow and depth of new snowfall forecast. This paper presents the progress of the related technology development in high resolution numerical weather forecast model, fine gridded QPF, gridded precipitation type and depth of new snowfall forecast and refined QPF verification. Finally, the existing problems and future developments of the current fine gridded QPF technology are discussed.
