A Lenticular Cloud Over Hawai'i


Explanation:
Can a cloud do that?

Actually, pictured above are several
clouds all stacked up into one striking
lenticular cloud.

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.

The above picture was taken near Mauna Kea,
Hawaii,
USA.
