More Undular Bores

Posted by jns on October 23, 2007

For those who enjoyed the pictures a few days ago of undular bores — atmospheric waves visible in clouds — here are a few more treats via NASA’s Earth Observatory project.

This time the waves are in the atmosphere off the west coast of Africa, in a couple of satellite photos captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites on October 9, 2007. Take a few moments to read the informative text on the page, too.

(While you’re there, you might want to look at the dramatic satellite photos of the wildfires in Southern California.)
