Double Intensification of Typhoon Gloria, 1974 and a Brief Review of Similar Occurrences.

Abstract

In November 1974 Typhoon Gloria displayed unusual intensity fluctuations while traversing the Philippine Sea. The typhoon exhibited two marked intensifications separated by a period of weakening lasting 12 hr. A chronological examination of this unusual behavior utilizing aircraft reconnaissance and satellite data is presented with particular emphasis on the evolution of the central core region. A parallel between observed events, and results demonstrated in a tropical cyclone numerical model responding to artificial enhancement of the convective heating functions is noted. Similar occurrences of double depening of typhoons in the Western Pacific are reviewed to determine Gloria's uniqueness. (Author)
