The Chaiten Volcano in Chile erupted on Friday, May 2, 2008. This image, captured May 3, shows the enormous ash plume rising high over the Andes mountains, drifting across Argentina, and dissipates over the Atlantic Ocean. Ash closed schools, roads, and an airport in Argentina, hundreds of kilometers away from the volcano, said AFP.
On Tuesday, May 6, 2008, the volcano erupted again, spewing pyroclastic materials like hot ash, gas and rocks 19 miles into the air. This image was captured that same day by the MODIS on the Terra satellite, during its morning overpass. The resulting plume from the volcano was again visible over Argentina, stretching to the ocean.

Welcome to JetStream, the National Weather Service Online Weather School. This site is designed to help educators, emergency managers, or anyone interested in learning about weather and weather safety.
The information contained in JetStream is arranged by subject; beginning with global and large scale weather patterns followed by lessons on air masses, wind patterns, cloud formations, thunderstorms, lightning, hail, damaging winds, tornados, tropical storms, cyclones and flooding. Interspersed in JetStream are "Learning Lessons" which can be used to enhance the educational experience.
You are free to use the materials in any manner you wish. We welcome your feedback on this project. Your input will greatly assist others in teaching the "hows" and "whys" of weather. Not sure where to begin? Click to see all topics in JetStream in the Topic Matrix. Contact Us:
