A review of hydrometeorological research is presented from aspects of quantitative precipitation estimation (QPE) and forescasting (QPF), hydrological model, hydrometeorological forecasting and flood forecasting. The investigation shows that the raingaugeradarsatellite quantitative precipitation analysis method is the main way for the high resolution precipitation distribution of quantitative precipitation estimation, and the ensemble prediction precipitation system based on NWP multimodel is a chief way for the high accuracy of quantitative precipitation forecast. Meanwhile, the distributed hydrological model is the development direction of hydrological model. The incorporation of quantitative precipitation forecasts into a hydrometeorological and flood forecasting system can increase flood forecast lead times. Hydrological ensemble forecasting system is the most popular prediction technique in the world and the bidirectional feedback model combining NWP model and hydrological model is another future development direction.
