Why does Jupiter have such powerful storms, including the Great Red Spot?

Jupiter’s atmosphere is extremely dynamic because the planet rotates in just under 10 hours while also releasing more heat than it receives from the Sun. That internal heat helps power convection, creating large storms and bands of east-west winds. The Great Red Spot is a giant anticyclonic storm larger than Earth, observed for at least 150 years and probably longer. Because Jupiter has no solid surface to quickly slow it down, storms can remain active for very long periods. Spacecraft such as Voyager, Galileo, Juno, and others have shown that Jupiter’s weather system is one of the most energetic in the Solar System.
