How It Works
Kelvin-Helmholtz instabilities occur when two fluids move at different speeds, creating shear forces that lead to the formation of wave-like structures. In the context of the Sun, these instabilities manifest as vortices at the edges of granules, which are large convective cells on the solar surface.
