Abstract:
The forecasting operation of quantitative hydrometeorology with accurate spatiotemporal distribution is to meet the demands of the national disaster prevention and mitigation, major projects support, expanding impacted forecasting and risk warning. Although great progresses in the hydrometeorological forecasting have been made in National Meteorological Centre in the recent years, there are still many gaps compared with the advanced forecasting technology in foreign countries. The current development of technique and operation status of the hydrometeorological forecasting was reviewed in this paper. In addition, the current challenges facing China were summarized and the corresponding measures and further development plans were proposed. At present, the main techniques on hydrometeorological forecasting can be classified as two types: the rainfall threshold model based on statistical theory and the distributed hydrological model. Moreover, the atmospherichydrologicalgeological model based on big data analysis and artificial intelligence technique will play important roles in the hydrometeorological forecasting. Hydrometeorological monitoring with satellite, radar and gauge observations is the foundation of hydrometeorological forecasting. Hydrometeorological forecasting based on seamless fine intelligentandgrid QPF and hydrometeorological ensemble forecasting model will be the important development directions of the hydrological forecasting in the future.
