- Close-up of W942241S, showing a part of the sloped anvil cloud and the rake pattern of irregular mamma created by sinking air. The cloud underside develops parallel grooves and ridges as the fallout organizes into “drainage” lines along it. These appear to radiate outward, due to perspective, and are aligned down the slope across the protruding ridges of thicker fallout.
