If t is the temperature approached simultaneously by the temperature of the sea and atmosphere, 

 it is obvious that 



On the basis of formula (6) we have

Assume that the height of the active layer of the atmosphere equals approximately 3,000 m, 

 the depth of the active layer of the sea is about 30 m, the initial air temperature is -10° and the 

 initial water temperature is +2°. On the basis of formulae (10) and (11) we have 



/ = + 1°.6. 



If the coefficient B in formula (4) is known, it is possible to determine approximately the 

 time interval during which the sea temperature would, under the Influence of cold wind, drop to 

 any given temperature, e.g., to the freezing temperature.
