after their discovery of Kelvin-Helmholtz instability. The two had studied the physics - the fluid dynamic, in particular - behind the atmospheric instability that creates unique clouds.

2005; Komarova and Hulscher, 2000]. Other examples are the Rayleigh-Taylor instability which occurs any time a dense heavy fluid is being accelerated by a light fluid [Sharp, 1984], the Kelvin ...

Known as Kelvin-Helmholtz clouds, they form when a faster ... "They also indicate instability in the atmosphere, which can help identify areas of turbulence for aircraft." They added: "This ...
