Use of Integrated Observations to Improve 0–36 h Flood Forecasting:Development and Application of a Coupled Atmosphere-Hydrology System in the Nanpan River Basin, China

The accuracy of 0–36 h real-time flood forecasting is largely determined by the quantitative precipitation forecasts (QPFs), but convective weather remains a significant challenge for numerical weather prediction systems. Therefore, it is crucial to improve the QPFs’ accuracies to predict and prevent flash flood disasters.
