This work is meant to demonstrate that, in the special synoptic conditions, on the surface of the Black Sea, a baric depression is being formed. This depression is formed when the Black Sea's water temperature is higher than the surrounding continental ground's temperature. There are situations when the baric depression of the Black Sea occurs because of the consequences of the movement of another baric depression from the east of the Mediterranean Sea to its north-east side. Due to the high atmospheric pressure of the continental zone that's surrounding the Black Sea, the baric depression will get a retrograde movement, towards the north or north-west. Eventually, this depression occludes in the eastern continental zone of Europe or even near the Baltic Sea. During a retrograde movement of a baric depression, the atmospheric precipitations will fall in big quantities, in many situations, causing flood
