Abstract

A technique is proposed for estimating tropical cyclone central pressure and surface wind speeds outside of the radius of maximum wind speed from the 55.45 GHz channel of the Scanning Microwave Spectrometer on board the Nimbus 6 satellite. The method was developed using measurements over eight typhoons and five hurricanes during 1975.
