Regional features of atmospheric precipitations in winter period on northern macroslope of Hamar-Daban ridge (South Pribaikalye)

The sum of hard atmospheric precipitations (mm) on observation of two meteorological stations, located at various hypsometric levels of northern macroslope of Hamar-Daban ridge (South Pribaikalye) is analysed. Are statistically processed paleocrystic (10, 29, 39 years) sequences of following data: dates of creation and going out constant snow cover; duration of period with stable snow cover; percentage ratio of hard atmospheric pre-cipitations which has dropped out during the various periods of winter season; percentage ratio of hard atmos-pheric precipitations on months from the sum of hard atmospheric precipitations for phenological year. In re-gime of atmospheric precipitations which is dropping out in high-mountainous landscapes and at coast of lake Baikal are revealed as distinctive features and as the common ones.
