ELI5: why does the giant red spot on Jupiter keep on going? If it's a storm why hasn't it just blown its self out/dispersed over time? How long will it last before it does go?

The Hubble observations indicate that the GRS is getting smaller by 580 miles per year along its major axis and its shape is changing from an oval to a circle. At the current rate, the storm is expected to become circular in four years. The vortex could completely disappear or grow larger, since the fate of such storms (even storms on Earth) is difficult to model and predict precisely due to their complexity. (Looked that up on Hubble's website)
