The Fermi bubbles were discovered in 2010 by NASA’s Fermi Gamma-ray Space Telescope. The two orbs form an hourglass structure ...

Global warming does not affect our planet evenly. Some areas such as the Arctic region or high mountain peaks warm faster ...

Kelvin-Helmholtz clouds, often called wave clouds, develop when two layers of air with different densities move at varying ...

Weather Rare, Kelvin-Helmholtz wave clouds spotted in central North Carolina These wave clouds will form due to differing wind speeds within the cloud layer.

Anne Wilkie posted on X. What she saw was a Kelvin-Helmholtz wave cloud, named after Hermann von Helmholtz, who discovered the atmospheric instability that leads to this phenomenon. These waves in ...

A woman in Calgary, Alberta, Canada, saw a strange, wavy cloud in the sky on Feb. 22, 2025, and took to X, formerly known as Twitter, to crowdsource an answer. "Does anyone know what is happening here ...

Experts believe it was likely a rare Kelvin-Helmholtz cloud, created when two layers of air move at different speeds, resembling ocean waves in the sky.

This causes the cloud to take on the shape of rolling waves. Called Kelvin Helmholtz clouds, or just wave clouds, these clouds are a sign of turbulence in the air.

Rare clouds could be seen from parts of the Highlands on Saturday afternoon. Called Kelvin Helmholtz, they resemble rolling ocean waves and similar patterns have been seen by astronomers on ...

On Dec. 2, 2024, huge, towering waves appeared in the sky above Montreal, Que. The clouds, called Kelvin-Helmholtz clouds, form when a layer of faster-moving wind sits above a layer of slower ...

The clouds, called Kelvin-Helmholtz clouds, form when a layer of faster-moving wind sits above a layer of slower-moving wind, a phenomenon also referred to as vertical shear.
