Low-Pressure Monitoring

MTSAT observations provide plenty of information about the movement and development of low-pressure systems. The images it observes contribute to the analysis of low-pressure areas and the appropriate announcement of weather information. The images here show a low-pressure system that developed rapidly and strongly over the ocean to the east of Japan. The infrared images show a large spiral pattern that formed from January 2-3 of 2006. Simultaneous water vapor images show the intrusion of cold and dry air into the low-pressure system meandering anticlockwise from the west.
