Lenticular Clouds Poster

My poster for our weather poster series for Weather Underground. Lenticular clouds are lens shaped and form over/around mountains, they are sometimes mistaken for UFOs. Attached is a larger version, where you read about this weather phenomenon.

We created this series to celebrate the 20th birthday of Weather Underground! There are free downloads available (wallpapers, 8x10 print), and a new one comes out every week!
