A method is proposed for evaluating the relation between GMS cloud images and weather charts. Changes of power, influential area, migration of typhoon and those of migratory low pressure areas are related to the area, configuration, strength and movements of cloud systems. According to the former study, cloud systems of cumulus and stratus are taken into consideration. It is because that the influences from those cloud systems to weather conditions are predominant. Effects of sea surface temperature in season and latitude on infrared the brightness-temperature of edge part of cloud systems are taken into account in extracting cloud system from the GMS images. Relations between parameters obtained from cloud systems and weather charts are shown closely related, and rises and falls of typhoon and/or low pressure area are understood to follow those of cumulus systems, as the results of the study.
