Then they notice a cloud formation that looks like a dolphin, or a boat, or letters of the alphabet. But few are fortunate enough to see Kelvin-Helmholtz clouds, which look like a pattern of ocean ...

The wave clouds were crafted by a phenomenon known as Kelvin-Helmholtz instability, which occurs as a result of differences in air density in adjacent layers of the sky. Moisture and strong winds ...

It seems quite rare." Local meteorologist Jan Null called the clouds captured in Harrison's image "a spectacular example of Kelvin-Helmholtz wave clouds." Indeed, these types of clouds get their ...

If you ever see these clouds for yourself, it will most likely be close to sunset or sunrise when the atmosphere has the best potential for a temperature inversion.Kelvin-Helmholtz clouds show ...

Recently, Linda Schuff shared a photo with us through Chime In of a unique and puzzling cloud formation. She also asked for an explanation as to what it is. These are known as Kelvin-Helmholtz ...

In one part of our area, the clouds were doing the same Sunday afternoon. In a rare showing Sunday, Martina Renaud in Cameron spotted "Kelvin-Helmholtz" wave clouds. Kelvin-Helmholtz wave clouds ...

if you’re lucky enough to see them. This week, it’s a brief primer on “Kelvin-Helmholtz clouds” or “KH clouds” or “fluctus clouds,” lots of names for the same thing. * Let’s ...

Residents of and near Whidbey Island witnessed a weather phenomenon on Tuesday as "wave clouds" lined the horizon. Kelvin-Helmholtz clouds or fluctus clouds, as the formations are named ...

(See the photo below.) They're called Kelvin-Helmholtz clouds. In simple terms, they happen when a stable layer develops in the atmosphere and separates strong winds aloft from weak winds below.
