Has anybody ever tried to surf in the sky? Look at these monster waves!
These wild waves in this weird sunrise sky have been spotted over Germany. And this weird sky phenomenon is called a Kelvin-Helmholtz cloud instability! Amazing nature!
On January 2015, the German sky was covered by weird wave-shaped clouds… And they baffled pretty much every workers that had seen them.
As if the sky had transformed into a mighty ocean.
This is a rare phenomenon called Kelvin-Helmholtz instability or Kelvin-Helmholtz clouds.
A Kelvin Helmholtz instability forms where there’s a velocity difference across the interface between two fluids: for example, wind blowing over water.
The characteristic wave structure in this type of cloud often occurs when two different layers of air in our atmosphere are moving at different speeds.
The upper layers of air are moving at higher speeds and will often scoop the top of the cloud layer into these wave-like rolling structures.
he clouds often form on windy days, when there’s a difference in densities of the air, for exmaple, during a temperature inversion. These clouds are often good indicators of atmospheric instability and the presence of turbulence for aircraft.
