We were driving in a relatively remote area in Iceland and I noticed this rather unusual cloud formation. So I absolutely had to photograph it. Is it a particular type of cloud or just a very unusual formation? This cloud stayed like this for a few minutes and then gradually dissipated.
Nikon D7100 with 18 to 300 mm lens shot at 22mm and 31 mm.
We told Anne that it is a particular type of cloud, called a lenticular cloud. These sorts of clouds sometimes cause UFO reports. You’ll find an explanation for how the clouds form – and lots more photos of them – here.
Thank you for contributing to EarthSky, Anne!
Bottom line: Spectacular lenticular cloud over Iceland in May, 2015.
