The Black Sea is untidal because the maximum value of tide near the Nothem shoreline is not greater than 0.08 m. That is why there are no typical tidal flats there. Nevertheless short-term changes of sea level take place. They are caused not by tides but by winds of gale force. If the wind is blowing landward, the water level near the shoreline is rising, if the wind is of the opposite direction, the level lowers relatively the average long-term value. The higher the wind velocity and the time of its action, the greater the amplitude of windy fluctuations of the level. It reaches the maximum in the tops of bays and harbours when windy vector acts along the normal to the shoreline, when land surfaces and nearshore sea bottom are the gentlest.
