Kelvin–Helmholtz clouds, I saw some of those over Galway during the summer, obviously not as dramatic as that but an impressive sight all the same

These clouds are also known as billow clouds, shear-gravity clouds, KHI clouds, or Kelvin-Helmholtz billows. The rolling eddies seen at the top of the cloud layers are usually evenly spaced and easily identifiable. The clouds are named for Lord Kelvin and Hermann von Helmholtz. These clouds are often good indicators of atmospheric instability and the presence of turbulence for aircraft.

Examples of such clouds over Swords, Dublin earlier this year. Jedward Clouds!!
