Abstract

The track followed by a tropical storm, which moved in the vicinity of Calcutta on 21 September 1962, as delineated from radar observations, is described and discussed with reference to the ellipticity of its radar eye in the course of its recurvature around the radar station. The gyration of the major axis of the elliptical eye during recurvature is compared with similar features of hurricanes in the Caribbean Sea discussed by Sadowski. His inference that the gyration of the major axis and its orientation with respect to the storm track may have prognostic significance is not supported by this study. The eye manifested even by a. weak storm after it moved overland suggests the existence of sustained descending currents at the centres of weak tropical storms also.
