For water vapor the effort to evaluate a transfer coefficient from the 

 238 trajectories was less successful. The linear relation, 



L = ^e Vo (% - ^)> (2) 



(L, the latent heat transfer rate in ly day' , Vo the surface wind in 

 m sec' , q^ and qo the dimensionless specific humidity at the sea surface 

 and in the "surface" air) could not be verified by the data because of the 

 large scatter (low correlation). A value of Kg was determined, nonetheless, 

 from mean values of Vq (qg - qo) and L. Table 2 shows this (dubious) value 

 of Ke together with some others .

Manabe (1958) has applied the line integral method for computing the 

 horizontal flux divergence of latent and sensible heat to the Japan Sea with 

 very satisfactory results . Unfortunately, Manabe did not use his data to 

 test the parametric transfer formula for sensible heat as he did for evapora- 

 tion . This task remains to be done . 



B. Indirect Computations of Energy Transfer 



The errors in adiabatic numerical prediction models are in part due to 

 sea-air energy transfers, although other factors, notably condensation, may

6 ra sec"-^ - and a smooth surface, to 11. at higher speeds -8 m sec' - 

 and presumably a rougher surface . )
