Cloud ID - Kelvin Helmholtz waves?
December 2, 2023 7:54 AM   Subscribe

Are these the remnants of Kelvin Helmholtz waves? I'm an amateur cloud spotter and have seen KH waves once before. These clouds from yesterday (Dec 1, 2023) in Boston, MA, US, were the only clouds in the sky, and I had a 360° view to tree-top level. Wind was southwest, 10mph.

Best answer: Certainly looks like they could be. Your pics are very similar to others I've seen that have KH waves at the end of their life cycle.

Response by poster: Ok, confirming they're Kelvin Helmholtz. Someone caught them on video about 100 miles away traveling toward Boston.
