Lenticular clouds over on May 10, 2007, by PhotoGallery/Iggor

Lenticular wave clouds are formed when air moves up over mountains, cooling sufficiently for condensation to take place. Sometimes multiple lenticular wave clouds like this are formed downstream from the original cloud. Note that the cloud appears to be sitting still but actually the air continually forms the cloud as it flows over the mountain. This picture was taken from the parking lot of Mount Mitchell, NC, the highest point east of the Mississippi at 6684 feet. We are looking northeasterly I believe. This is the second photo I took of these lenticular wave clouds. These type of wave clouds were not uncommon in the mountains of NC, but these are certainly the most beautiful I have seen. I am unsure of the date this photo was taken but I`m guessing March 1992. This is one of my favorite photos.

Lenticular cloud over the Rockies October 25, 2005, by PhotoGallery/Raligard.

Clouds are formed when water vapor condenses around particles in the air. In this case, the smoke provided ample particles. This type of cloud is known as pyrocumulus. This picture was taken from Long Beach, NC. I was there on vacation and saw this huge plume of smoke emanating from a large forest fire considerably inland. The date of this picture is unknown. It is almost certainly either June or August - my vacation months, during the early 1990`s.
