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 ...

A new paper published in the journal Physical Review Research provides experimental support for the hypothesis that hand clapping essentially acts like a Helmholtz resonator—akin to the hum ...

Kelvin-Helmholtz instability, which transforms fair weather clouds into the form of crashing ocean waves, is a rare and wondrous phenomenon. One of the best examples I’ve ever seen is in a video ...

The chosen solution in his thesis are Helmholtz resonators, which are a kind of acoustic spring. Using a carefully selected opening into the cavity, frequencies can be filtered out, and ...

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 ...

A photo of the Kelvin-Helmholtz clouds was captured by Joy Patrick looking out to the sea at Trimingham in Norfolk. She spotted them from her bedroom window on Sunday evening as the Eastern Daily ...

The Helmholtz Space Life Sciences Research School (SpaceLife) is funded by the Helmholtz Association (Helmholtz-Gemeinschaft) for a period of six years (beginning in April 2009) and receives ...
