Abstract:

We investigated the main precipitation modes over Mongolia and southern part of Eastern Siberia in midsummer. We used precipitation data from GPCC archive (1979–2013). The EOF analysis was applied to the interannual change in July precipitation for two areas: “big” (90–120°E; 35–70°N) and “small” (the Selenga basin, 96–110°E; 46–54°N). The total amount of precipitation within the Selenga basin in July was calculated. According to the obtained estimates two leading EOFs (EOF1 + EOF2) explains 32.3 and 48.9% of the total variance for the big and small areas, respectively.

Keywords:

precipitation, seesaw modes, Lake Baikal, the Selenga River, empirical orthogonal functions
