Low Pressure System in the Gulf of Alaska

Low Pressure System in the Gulf of Alaska

The MODIS instrument aboard NASA’s Aqua satellite captured this true-color image of a large low pressure system spinning in the Gulf of Alaska on August 17, 2004 at 22:45 UTC. This area of the world is famous for strong, persisent low pressure systems because of the persistent flow of semi-permanent pressure systems north (the polar easterlies) and south (the subtropical high) of the area.

The MODIS Rapid Response System provides this image at additional resolutions and formats.
