Description

Satellite cloud photographs are very important for a clearer understanding of meteorological features of almost every scale and their interrelationships. In this paper, satellite derived information, particularly cirrus-level wind estimates made from cloud photographs, are used to recount the story of twin tropical cyclones--ANNIE and GILDA-- which formed about the same time on opposite sides of the equator in the Western Pacific during November 1967. Throughout the life cycle of the twins, it is the change which takes place in the cirrus-level wind field that enables the meteorologist to discern the step by step development of the respective cyclones as well as the interaction between the high-level winds of the two hemispheres and the twins themselves.
