Abstract: An assessment of the possibilities of using the COSMO-Ru system for short-term forecasting of runoff of Russian rivers is carried out. An analysis of the forecast quality of the daily precipitation layer and average daily temperature of the surface air layer using this system is performed for 2081 weather stations. The quality characteristics of these forecasts are mapped. A forecast correction method was applied, which made it possible to increase the accuracy of forecasts on average by 20% for the precipitation layer and by 15% for air temperature. The quality of forecasting meteorological parameters averaged over the territory of 590 river basins turned out to be satisfactory for the precipitation layer and good for air temperature. The results give reason for a positive assessment of the possibilities of using the COSMO-Ru system for short-term forecasting of runoff of Russian rivers. [ABSTRACT FROM AUTHOR]
