Lenticular Clouds:
An amazing show given to us by the Arenla Volcano! How do these clouds form?
Normally, air moves much more horizontally than it does vertically. Sometimes, however, such as when wind comes off of a mountain or a hill, relatively strong vertical oscillations take place as the air stabilizes. The dry air at the top of an oscillation may be quite stratified in moisture content, and hence forms clouds at each layer where the air saturates with moisture. The result can be a lenticular cloud with a strongly layered appearance.
Come to Costa Rica and enjoy these spectacular Natural Shows!
