INTERACTION BETWEEN THE ATMOSPHERE AND THE OCEANS 235 



The cause of the variations in the heat content of the water or such 

 variations in volume transport as are described on p. 176, however, is not 

 understood. 



It is not yet possible to deal with the system atmosphere-ocean as one 

 unit, but it is obvious that, in treating separately the circulation of the 

 atmosphere, a thorough consideration of the interaction between the 

 atmosphere and the oceans is necessary.
