Kinematic structure of Hurricane Isabel (2003) near landfall from the Morehead City WSR-88D

The low-level wind structures, such as reflectivity, tangential, radial, vertical velocity and perturbation pressure, of hurricane Isabel, which made its landfall around 1700 UTC, were analyzed. The kinematic structure of the hurricane were observed by the Morehead City WSR-88D. The maxima Doppler velocities were found to exceed 50 ms ^-1 at the 0.5 elevation angle scans during the analysis. The hurricane possessed an eyewall, which had exceeded 60 km in radius associated with the primary wind maxima. It was found that the intensity of the Isabel was decreased with height as the tangential wind at 4 km was below 30 ms ^-1.
