Why does Jupiter have such powerful storms?

Jupiter spins once in just under 10 hours, which creates strong winds and intense atmospheric bands. It also gives off more energy than it gets from sunlight, likely because of leftover heat from its formation and slow contraction under gravity. That internal heat powers convection deep in the atmosphere, feeding massive storms and long-lived vortices. The best-known example is the Great Red Spot, a giant storm larger than Earth that has lasted for centuries. Jupiter's weather is far more energetic than Earth's because the planet is so large and rotates so quickly.
