摘要：With the development of space technology, the accuracy of weather forecasts has steadily improved over the years. Accordingly the QPE/QPF products have been improving so that it is possible to be gradually applied for hydrological purposes. However, it has been challenging to integrate QPE/QPF into real-time operational flood forecasting and disaster monitoring and warning because of the crucial gaps on temporal-spatial resolution, systematic uncertainty and methodology of application. Aiming to the challenges, meteorologists and hydrologists have made great efforts jointly and achieved evident progresses on improving QPE/QPF products to get closer to the hydrological requirements. This paper presents an overview of hydrological prospective on QPE/QPF products, challenges and gaps in QPE/QPF application in real-time operation, and some of the recent studies on improving QPE/QPF products for hydrological purposes.
