Kelvin-Helmholtz cloud (DI01175) Photo by Benjamin Foster
Kelvin-Helmholtz clouds resemble breaking waves in the ocean. They are usually the most developed near mountains or large hills. Wind deflected up and over a barrier, like a mountain, continues flowing through the air in a wavelike pattern. Complex evaporation and condensation patterns create the capped tops and cloudless troughs of the waves. These Kelvin-Helmholtz clouds were shot around 9:30 a.m., February 9, 2004, with a Nikon D100 and 28-200 lens.
