Storms with rapidly moving edges (from which the waves 
leave the storm) and hurricanes produce wave systems which are 
not covered by the above theoretical considerations. The theory 
can probably be applied to slowly movinz storms without too great 
an error. Also various successive temporarily stationary positions 
of a moving storm might yield fairly good results upon application 
of the theory. Hurricanes just do not come under the scope of 
the theory for reasons mentioned in Chapter 2. The Gaussian 
Lebesgue Rower Integral has a different form and a hurricane has 
no width because it is circular. Possibly in another paper and 
at another time, the problem will be treated for moving storms 
and for hurricanes. The above forecast model ought to work for 
a large number of practical cases.

There is still a joker in the deck. The functional forms of 
E5(# 58) for storm waves at sea are still unknown. From the re- 
sults of Deacon [1949], Donn [1949], arthur [1949], and Barber and 
Ursell [1948], a particular E,(y,9) must vary considerably over 
a range of 4 corresponding to a period range exceeding values 
of from below five seconds to above twenty seconds and over a range 
of © from forth-five to sixty degrees above and below the dominant 
direction of the winds in the storm. In the next chapter, adequate 
methods for the analysis of ocean wave records, and adequate pro- 
cedures for the determination of E,(y ,®) will be given. Then
