My Facebook feed this week has been abuzz with a recent photo of Kelvin-Helmholtz waves taken by Brad Peterson in Utah earlier this week. K-H waves are caused by rolls of turbulence between two smoothly flowing layers of air and were named for scientists Lord Kelvin and Hermann von Helmholtz. Over time the waves grow and appear to break like ocean waves, but they usually only last a few minutes. I’ve seen a few examples in my life, although none so spectacular as this.
