Meteorology: Clouds

Eerie "popcorn" clouds were seen in the NY skies this week - apparently, they're Mammatus clouds (and, yes, "mammatus" is from the same root as "mammary").

The Daily Mail has amazing photos of another new cloud formation, Asperatus clouds.

Check out Flickr for more photos of Mammatus and Asperatus clouds. I love this one. Ooh, I think I caught someone cheating on Flickr - here's one of those Daily Mail photos (by Ken Prior) being passed off as her own!
