To the Problem of Verification of Methods for Short-range Forecasting of Hydrological Parameters

Resumo

The main principles of the existing methodology for the verification of forecasting techniques in the absence of the sample volume impact on the accuracy of determination of statistical parameters are considered. A method is proposed for the verification, comparison, and selection of forecasting methods. The method is based on the persistence of the predicted phenomenon and allows creating optimum forecast schemes with account of priority of expected parameters of accuracy. It is anticipated that the obtained results will find application in the practice of hydrological forecasting.
