- Аннотация: The development of winter ski tourism and characteristics of ski resorts in various regions of Russiaare closely related to climatic conditions, the most important of which are the presence and duration of snowcover. For 2000–2021, a study of snow cover, the availability of optimal ski days (OSDs), and climatic indicatorsnecessary for artificial snowmaking at ski resorts located in different regions of Russia was performedusing data of the ERA5-Land reanalysis. The characteristics of snow cover and temperature from the reanalysisdata are compared with data of the meteorological network. The ERA5-Land data for temperature, precipitation,and snow cover thickness are well synchronized with the observational data, and estimates of theerror of trends in air temperature and snow cover depth according to the reanalysis data relative to the stationdata give satisfactory results. In the conditions of the current climate, the average and maximum thickness ofsnow cover in all resorts is sufficient for their functioning, but in 2000–2021, a decrease in both the maximumand average values of snow cover is noted in most resorts. The study shows that, in terms of snow and weatherconditions, the highest mountain resorts of the North Caucasus and Kirovsk (Murmansk oblast) are the mostprosperous, where thickness of the snow cover and duration of its occurrence, as well as a significant numberof OSDs sustains the stability of the resorts and creates favorable conditions for further development. A studyof the characteristics of snow cover at ski resorts is conducted using ERA5-Land reanalysis data. A comparisonof the characteristics of snow cover, precipitation, and temperature are made using reanalysis and meteorologicalnetwork data. In the current climate, the average and maximum snow depth at all resorts is sufficientfor their operation, but most resorts are experiencing a decrease in snow depth.
