The factors of interannual variability in minimum winter discharge of the rivers in the upper part of the Lena basin

A.V. Ignatov, V.V. Kravchenko

We investigate the formation of interannual variability in minimum winter discharge for a number of rivers in the upper part of the Lena basin depending on the eventual factors that are responsible for this variability. The study revealed the most important variables which can be used as predictors of the discharge parameters under consideration. We have constructed the regression models for predicting the parameters of minimum winter discharge with a 1-4-month predictability.
