where tm = temperature of sea surface durii^ the given time interval, 







t„ = air temperature at a given moment (more precisely, the temperature of the active 

 stratum of atmosphere), 



T = time, 



K = coefficient of heat transfer, i.e. , the amount of heat transferred through a unit sur- 

 face of sea to the atmosphere in unit time at a temperature difference equaling 1°. 



On the other hand, in consequence of heat transfer by the sea, the heat content of the atmos- 

 phere will increase according to the following formula: 



dQ = HaFCa^adta, (2) 



in which /7^= the height of the active stratum of atmosphere, 



Cg = the heat capacity of the air, 



6 = the density of the air. 

 Equating (1) to (2), we have 



Assuming for brevity that

Figure 8 presents schematically (the lower curve) the temperature variations with time in the 

 active layer of atmosphere which are affected by the warm sea. Temperature values are laid off on 

 the vertical axis, time values on the horizontal axis. It is seen from the figure how, with time, the 

 air temperature approaches the temperature of the sea surface. 



Formula (5), derived by me, is an approximation. It is delimited by the time interval during 

 which the temperature of sea surface can be considered as constant; In addition it accounts only for 

 the convective air intermixing.
