Abstract
The paper presents an estimate of annual precipitation amount for the winter period (1967-2006) in the basins of the Charysh and Anuy mountain rivers. A kinematic model for air mass movement when crossing orographic barriers is used for calculations. The initial data are monthly precipitation totals (November-March) obtained from meteorological and gaging stations located within the basins and at the adjacent territory. Based on the single-factor dependencies and multiple correlation/regression analysis, we assess the dependences of melt runoff depth on total precipitation for winter and flood (April-June) time periods for gaging stations “Charyshsky state farm” on Charysh river and “Anuysky state farm” on Anuy.
