 This approach is partly deductive, partly empirical in nature, 

 and assumes that the depth to which mixing will occur is a 

 function of three parameters: 



a. The amount by which the predicted wind speed will 

 exceed the critical wind speed Vc as demonstrated by Munk (19l)-7) 



b. The wave number, fi , associated with the predicted 

 sea state (^ = ^) . 



c. The initial stability — ^ , designated by E. 



P oZ 



Under these assumptions the following relationship was 

 derived: 



where 



D = depth of thermocline due to mixing, 

 Dq= original depth of thermocline, 



A,K = constants of proportionality which must be determined 

 by data, 



Pq,P = density in mixed and unmixed layers, respectively, 



t = time (units depend on units chosen for V and Vq ) . 



Further work must be done to determine whether this 



relationship can be developed as a practical prediction tool. 



For this reason, prediction examples have been confined where 



possible to those cases where the mean value of V was less than 



the 13 knots given as the value of V(, by Munk, 



Once the mixed layer due to turbulence D has been arrived
