Nature Walk: Cumulonimbus Clouds

“Cumulonimbus clouds have been called the Godfather of clouds. They inspire both awe and fear depending on whether they are going away from you or coming at you and possibly spawning high winds, hail and tornadoes. Often we see an anvil-like shape on the leading or trailing edge. In this case a collection of thunderheads congealed to form a supercell or multicell cloud. You can see the evidence of this at its base. This particular cloud appeared to be at least 100 miles wide and likely eight to 10 miles high. Note the moon at the far right.” -Carl Kurtz Note: Five separate images were put together to get this photo.
