Kerry Coffin from Bailey Island Maine was in the perfect spot to capture the beauty of these tsunami wave clouds Saturday evening. They’re a great example of Kelvin-Helmholtz instability waves named for Lord Kelvin, and Hermann von Helmholtz. Click here.
These wave clouds form the same way a wave crests or breaks on the ocean. In the case of these clouds from Saturday, a stronger wind present aloft was blowing over a lighter wind at the ground level. That set up drags the top of the cloud, creating a curled shape as you would see in the crest of and ocean wave.
Thanks again to Kerry Coffin who was in the right place at the right time to snap this great photo. I love to see weather related photos from around the state of Maine. If you snap a good one, and would like to share it, here are a few ways to contact me.
