we assume that in an area where a positive air temperature anomaly is encountered, the sea is 

 heated, the air moving over the area is also heated to the same degree. Simultaneously, the mois- 

 ture of the air increases and, consequently, its heat capacity also increases considerably.

Let us now assume that the mean yearly temperature of a water basin does not change. In 

 such a case the equation of heat balance will have the following form: 



Ril—A) — r — E + C+F + M — N + P-Q=0, 

 where R = cumulative solar radiation, 



A = albedo, 



r = effective reradiation, 



E = heat loss to evaporation and convection, 



C = heat Inflow at condensation, 



F = heat brought by continental runoff, 



M = heat brought into given basin by sea currents (+ pertains to a case when the tempera- 

 ture of inflowing waters is higher than the mean temperature of the basin).
