AWESOME LOOKING LENTICULAR CLOUDS

This is an awesome pic of Lenticular Clouds kudos to Brian Middleton.

Lenticular clouds (Altocumulus lenticularis) are stationary lens-shaped clouds that form in the troposphere, normally in perpendicular alignment to the wind direction. Lenticular clouds can be separated into altocumulus standing lenticularis (ACSL), stratocumulus standing lenticular (SCSL), and cirrocumulus standing lenticular (CCSL). Because of their shape, they have been offered as an explanation for some unidentified flying object (UFO) sightings.

Flight

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 to great distances. As of 2016 the gliding world records for both distance (over 3,000 km; 1,864 mi)^{[citation needed]} and absolute altitude (15,460 m; 50,721 ft)^[2] were set using such lift.
