NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

Cyclones on Satellite Images
comma-shaped cloud configuration

On satellite images, a midlatitude cyclone is often identifiable by a comma-shaped cloud mass.

A single cyclone can influence the weather over a large area, (in this case from Texas into Minnesota). This particular storm (in the satellite image above) left more than six inches of snow from Nebraska into Minnesota, while heavy rains occurred from Missouri into Texas.

MOVIE (QuickTime 1.3MB): Infrared Satellite Loop

Here is a movie loop of color enhanced infrared images spanning 18 hours. The center of the cyclone was initially located over the southcentral portions of the United States. As the cyclone evolved over time, notice the counterclockwise rotation of clouds around the cyclone center.
