The granules flicker rapidly, making the Sun look like a burbling witch's brew. Granules are the top of convection cycles that bring material from deep within the Sun to the surface.

Tornadoes, thunderstorms, and other weather patterns take place in the lowermost layer of the atmosphere, the troposphere.
Convection is responsible for much of the meteorology.
This happens on smoggy days in urban areas and everyday in the stratosphere. Figure 6 Planetary paisley. Like cream in coffee, clouds on the giant planet Jupiter bend and twist and curl into psychedelic patterns. These storm systems dwarf the Earth, superimposed for scale. Such turbulence is what happens when convection gets carried away.
