Desert Rain

Pictures of the effects of rainfall in Arizona:


Mammatus clouds over the Grand Canyon. The pendular hanging parts are downdrafts from an overhanging nimbocumulus anvil. They are very pretty, but quite nauseating to fly through in an airplane - quite turbulent! (photo by Doug Nering).


Hummingbird moth (also called hawkmoth) from Ahwatukee (on the fringe of the Phoenix metropolis). Very strange moths - look like hummingbirds, but very quiet! Tongues that are 5" or 6" long! (photo by Deborah McMillion-Nering).
