It should be remarked that for k=l, this wind model is 

 equivalent to the NWS-23 model. Another important point to note is 

 that the azimuthal variation of k automatically results in an 

 asymmetry of the wind field due to the translation of the storm. 

 From the NWS-23 model, this asymmetry has to be taken into account by 

 augmenting the maximum wind speed with the forward speed of the storm 

 and the cosine of the angle that depends upon the location of the 

 maximum wind relative to the storm path. 



b) Analytical pressure model 



The pressure profiles obtained from (69) using k obtained from 

 fitting the velocity profiles were not in good agreement with the 

 observed pressure profiles. This confirms Hollaiui's remark as 

 mentioned earlier. Therefore, the pressure profile 



P = P^ + (Pj^-Pj,)e(~^/^), (74) 



which is equivalent to (69) with k=l, was employed in this study.
