Why does it snow in Sochi in winter?

Located on the coast of the Black Sea, the warm and humid air from the Black Sea is in the south, and the Great Caucasus Mountains are in the north, which blocks the cold air from going south. This unique geographical condition by mountains and seas makes Sochi the northernmost subtropical climate zone on earth.

In winter, due to the influence of the west wind, there will be deep cyclones and precipitation, but in the northern mountainous areas or areas with abnormal climate, there will also be snowfall when encountering strong cold air.
