Nature is so cool. Sometime last year, some clouds — under the influence of what’s known as the Kelvin-Helmholtz phenomenon — came to pass in Alabama, Birmingham. The crest-like cloud formation happens when an upper layer of warm air moves faster than the denser, colder layer (with clouds or fog) below it, and surges it forward visibly. It looks pretty freaky.
