Mammatus on Fire

'This photograph was taken after a summer sunset when these clouds (Cumulonimbus mammatus) quickly formed in Jackson, Wyoming, USA. Mammatus clouds are special structures that are formed by downward vertical currents, which collide with other warm air rising. This collision gives rise to the characteristic bumps at their base as a result, and giving it its name from the Latin word "mamma". These clouds are usually formed in hot weather and are byproducts of intense storms located on its periphery. The light at sunset highlights the special shape of these striking cloud formations.'
