Seahorses in the Sky
Edie Garnier snapped this photo from his window in Georges River NS. Do you see what he sees?

Seahorses are fish. They live in water, breathe through gills and have a swim bladder. So what were they doing on the sky last month? Edie Garnier from Georges Riverm in Cape Breton sent along a great photo and wondered if these “seahorse-like” clouds have a name. They certainly do: they are wave clouds. A wave cloud is created by atmospheric internal waves, in this case Kelvin-Helmholtz waves.
Kelvin-Helmholtz billows are an indicator of atmospheric instability. They form when a layer of cloud is found beneath a layer of warmer air and the two layers happen to be moving in separate directions. These clouds often look more like ocean waves, but every now and gain, we get treated to a parade of seahorses in the sky!
Thanks you Edie...and great observation!
