Is this rainfall forecast good or bad? For flood forecasting, the answer is scale-dependent
journals.ametsoc.org
Abstract Quantitative precipitation forecasting benefits real-time streamflow forecasts by extending the lead time horizon. Uncertainties in QPF compromise these benefits. This study examined the...
