Coordinates of landfall of the hurricane 

 Position of hurricane center 



x ,y A point in the influence region 



x ,y A point along the coast determined by the inter- 



section of a line normal to the coast and pass- 

 ing through ( x p >y p ) 



cess 

 X ,Y ,X ,Y Coordinates of the coast and seaward boundary 



curves to be mapped 



Y Extent of the land influence for deforming the 



wind 



Z Plane of (x,y) 



S Extent of n (±) in the £-plane 



A Arc length 



At Surge algorithm time increment 



5 The alongshore curvilinear coordinate of the shelf 



coordinate system 



c s 

 y ,y Prorating factors for the length of the transform- 



generated curves 



A Half the horizontal extent of the region to be mapped 



in the Z or ?-plane 



y,v Functions transforming g and n to the stretched 



shelf coordinate system (S*,T*) 



(J) Ingress angle 



p.,P w Density of air and water 



a 2 , a Total and nth contribution to the "curvi linearity"
