Research Progress on Storm and Flood Forecasting

Storm flood disasters have always been a threat which is one of the worst natural disasters to human survival and development. Firstly, the development of real-time flood forecasting technique from experience model, lumped conceptual model and distributed mode were introduced. Secondly, the modern meteorological technology propelling the hydrological forecasting technology from both quantitative precipitation estimation (QPE) and quantitative precipitation forecasting (QPF) were reviewed. This paper shows that the mismatch time and space resolution between numerical weather prediction models and hydrological models are the major factors of restricting hydrological and meteorological coupling. Thirdly, some hydro-meteorological work done by Wuhan Institute of Heavy Rain, China Meteorological Administration in recent years were briefly introduced. The main work includes hydro-meteorological model research and application, the experiment of key technologies in hydrological and meteorological coupling, preliminary study of numerical model downscaling, real-time watershed hydro-meteorological forecasting system. Lastly, this paper holds that four kinds of work are particularly important. They are: strengthening the mechanism of hydrological process, strengthening the study of the distributed hydrological model and geographic information system coupling, strengthening the research on hydrological and meteorological coupling and strengthening the research into hydrological ensemble forecasting.
