“There were just these massive UFO type clouds and they became more defined as time passed,” said Monique Jackson.
They are in fact lenticular clouds, according to CNN meteorologist Derek Van Dam.
Lenticular clouds (Altocumulus lenticularis) are stationary lens-shaped clouds that form in the troposphere, normally in perpendicular alignment to the wind direction.
Because of their shape, they have been offered as an explanation for some Unidentified Flying Object (UFO) sightings.
As air flows along the surface of the Earth, it encounters obstructions. These are man-made objects, such as buildings and bridges, and natural features, like hills, valleys, and mountains.
Pilots of powered aircraft tend to avoid flying near lenticular clouds because of the turbulence of the rotor systems that accompany them, but glider pilots actively seek them out.
The precise location of the rising air mass is fairly easy to predict from the orientation of the clouds. “Wave lift” of this kind is often very smooth and strong, and enables gliders to soar to remarkable altitudes and great distances.
