Sea Level Pressure and Infrared Satellite - A strong cyclone moving across the country is evident in the satellite imagery from April 2001. The strength of the storm is indicated by the sea level pressure values superimposed on the cloud pattern. An animation of these images allows for the study of the track and intensity of the storm and provides an indication as to the type of weather various parts of the United States experienced.
