Chuck and a Green Core
The greenish core of a menacing HP (heavy-precipitation) supercell looms over the Texas high plains, behind a ragged arcus cloud. To the right, a rotating wall cloud wraps up in a front-flank outflow notch. To the left, renowned storm observer and atmospheric scientist Dr. Chuck Doswell captures the wall cloud with his medium-format camera. The green tint results from extensive refraction of sunlight through tens of thousands of feet of heavy rain and hail aloft. This supercell produced destructive hail larger than baseballs, and is the same spectacular storm featured in these scenes from the Wall Cloud Wall.
