Strong winds and rain here today put me in mind of the big red eye storm on Jupiter - more than 300 years old, and twice as big as Earth, is (relatively) common knowledge.
However recently another 2 storms are brewing - Red Spot Jnr. and little Red Spot. (Scientists think these storms turn red when they reach velocities that suck up material from lower down in the atmosphere.)
Given that Jupiter is about 1,300 times bigger than Earth but rotates on its axis every ten hours, there is enormous turbulence, especially around the equator. Estimates of the wind speeds within the red storms varies between 350 and 600 kilometres per hour.
