Mathematical models for long-term prediction of mountainous river runoff: methods, information and results.

Abstract Unlike traditional statistical methods, a mathematical model is used to solve the problem of the long-term prediction of mountainous river runoff. The paper describes the structure of a basic model and ways of numerical presentation of macroscale rainfall fields in mountains as well as the computation of their parameters in conditions with complex relief and lack of information. The encouraging results and estimates of forecasts are discussed.
