Abstract
The article examines the features of snow cover occurrence in the Perm region for the 30 year period. Data about the onset, destruction, duration of steady snow cover and snow depth are given. Statistical parameters for single stations and the entire region are calculated. Spatio-temporal variability of basic snow cover characteristics is analyzed. It is shown that the dates of onset and destruction of steady snow cover have shifted to later terms during 1988-2018 period. It is determined that the increase in the number of days with a stable snow cover was observed after a long reduction in recent years. The features of the spatial structure of snow cover distribution in the region are revealed. It is established that the snow depth decreased until the end of the 00-ies of the XXI century, in recent years there has been a tendency to increase in values.
