The goal of this study is to show all tracks of cyclones and the tracks of storm cyclones with moderate and severe storm wind entering European Russia (ER) from regions of different genesis. NCEP/NCAR DOE reanalysis data from 1979 to 2018 are used in the study. The storm tracks are calculated with an automated cyclone detection/tracking algorithm based on a 6-hourly MSLP. A significant part of the moderate and severe storms enters European Russia from the North and Baltic Seas, most of them are accompanied by an extreme sea level pressure. The maximum severe storm wind density in the western and central part of ER, both in winter and in summer, half of the year, is associated with cyclones from the Baltic Sea genesis region. The Mediterranean storm cyclones affect the Black Sea region and the south-east region of ER. Only about 57% of the Mediterranean storms entering ER are accompanied by an extreme sea level pressure. The cyclone center density and severe wind density patterns show that the position of the storm wind is shifted to south from the regions of cyclone centers. This feature is characteristic for all cyclone genesis groups, both in winter and summer, half of the year.
