There are clouds that look like waves
We tend to think of waves occurring in the ocean. But there are actually clouds that look like waves of water. In June 2019, some lucky people in Roanoke, ******ia, witnessed what are called Kelvin-Helmholtz clouds when they appeared in the sky above Smith Mountain.
The formation can occur on windy days, "when there is a strong vertical shear—meaning the wind is blowing faster at upper levels in the atmosphere compared to the wind at lower levels, causing the clouds to look like rolling waves," according to ABC News.
