LENTICULAR CLOUDS OVER MT. RAINIER, WASHINGTON, USA
10/07/13
Hi Everyone. Today we are going to the state of Washington, USA
to see something unusual to most areas. We are going to see
the lenticular clouds over Mt. Rainier.
First, we need an explanation of what lenticular clouds are.
This is information from Wikipedia about the clouds.
"Where stable moist air flows over a mountain or a range of
mountains, a series of large-scale standing waves may form on the
downwind side. If the temperature at the crest of the wave drops
to the dew point, moisture in the air may condense to form
lenticular clouds. As the moist air moves back down into the trough
of the wave, the cloud may evaporate back into vapor. Under certain
conditions, long strings of lenticular clouds can form near the crest of
each successive wave, creating a formation known as a "wave cloud." The
wave systems cause large vertical air movements and so enough water vapor
may condense to produce precipitation. The clouds have been mistaken for UFOs
(or "visual cover" for UFOs) because these clouds have a characteristic lens
appearance and smooth saucer-like shape. Bright colors (called irisation) are sometimes
seen along the edge of lenticular clouds. These clouds have also been
known to form in cases where a mountain does not exist, but
rather as the result of shear winds created by a front."
I hope you have enjoyed this unusual display of clouds.
