    All is set for a cold wave over the southeast Europe, because of a strong area of high pressure, EKART, that’s dominating the atmospheric scenery over most of Europe.

    Since it spins in clock wise, it’s pushing down arctic cold air mass, that will be reaching southeastern areas by tomorrow, such as Turkey, Georgia, Azerbaijan, then even more down south.

    The result of that, it will be an amazing and interesting meteorologic phenomenon: the so-called Black sea snow effect, which is able to give snowfalls along north Turkey.

    How does that phenomenon happen?

    First, it occurs in colder atmospheric conditions. Indeed, cold air moves over warmer sea water, heating up and picking up vapor. Consequently, it rises up through cold air above, creating bands of clouds that are able to provide fresh snowfalls, particularly at the top of hills, where temperatures are lower.

    Besides, in conditions of strong winds, the snow can fall over coastal areas, giving amazing and unexpected sceneries.

    Grazie Paolo, great article!
    Lake effect snow is also common across the Great Lakes region (USA)
    when cold air from Canada, moves across the open waters of the Great Lakes.

    Wind direction is a key component in determining which areas will receive lake effect snow. Heavy snow may be falling in one location, while the sun may be shining just a mile or two away in either direction. The physical geography of the land and water is also important.
