| description | The paper presents results of studies of the dynamics of snow cover characteristics along the Lake Baikal coast for the years 1961–2009. Statistical characteristics of the following elements: snow depth, duration of the period with snow cover, dates of onset and destruction of snow cover, were calculated from data of local meteorological stations. Mean annual snow depth in the region varies from 1 to 36 cm, while the maximal ten-day values changes from 12 cm on the West coast up to 60–86 cm on the East coast. Mean duration of the snow cover in the Baikal region is 138 days, while on the East coast it lasts for 178 days, and on the West one – for 126 days. Long-term trends of the snow cover characteristics are mostly statistically insignificant. However, at the end of the above period dates of the snow cover onset and destruction has been shifted to earlier dates. The inter-annual variability of these dates reaches 30 days. A linear dependence of the snow cover depth on the mean air temperature and the precipitation amount for the cold season was revealed with correlation coefficients from 0.31 to 0.89. |
