In this case two wind fields typical of intense hurricanes were investigated, the first representing a stationary storm, and the second representing the identical storm translating to the north at 15 m/s. The spatial distribution of wind speed and direction, typical for a strong northward-moving hurricane, is shown in Fig. 12.1. Also shown are the output grid points selected for display of the 2d spectra. The maximum wind speed of 40 m/s is located 50 km northeast of the eye. There is a pronounced asymmetry in wind speed (wind stronger to the east and north of the center) and a north—south asymmetry in wind direction (strong inflow in the rear quadrants).
