But few are fortunate enough to see Kelvin-Helmholtz clouds, which look like a pattern of ocean waves in the sky. Kelvin-Helmholtz clouds, also known as fluctus clouds, is a rare phenomenon that's ...

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 ...

In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing Kelvin waves in superfluid helium-4. First described by Lord Kelvin in ...

The pleasant rhythm of waves lapping at the lake shore is caused by wind blowing over the water at a faster speed than the water is moving. This same thing happens in the air all the time, but the ...

later known as a Kelvin wave. While these waves have been observed in classical fluids like water and air, their existence in quantum fluids has remained largely theoretical due to the extreme ...

The rare event is being caused by two key weather drivers – or tropical waves – known as the Madden Julian Oscillation (MJO) and an equatorial Kelvin Wave. We sat down with the Bureau of ...
