p = p , that is, for the development of the first characteristic 

 wave in the sea, which was called the "short sea" or "sea" and 

 characterized by a phase velocity smaller than the wind velocity. 

 From a fetch of 300 km, this "sea" or "p -wave" would have attained 

 its maximum height, length and final steepness. But beyond this 

 state, the growth of the sea continues, and longer waves are gener- 

 ated by the wind. The complex sea will be nearly fully arisen when 

 the fetch is 500 km. These results will be discussed later on in 

 more detail, but they show that the uncertainties involved in our 

 assumptions for the state p<l/3 play only a minor role, when the 

 development of the complex sea with "ages" of the waves p>l/3 is 

 considered. 



The condition for fully developed sea at any given wind velocity 

 is A = D. With this and the equations (34) and (36), 6 is related 

 in a fixed manner to the wind velocity v (see also [8]). But from 

 equations (37)

M(l) = Me P™ , 



and according to (38) 



M(l) = M(p)e2^^1-P) . 

 If we introduce this in (57) y we have

where M(l) according to (36) may be written
