So that storm is bigger than earth because it has been raging for years. Jupiter is the most violent planet in the solar system due to: Storms, Yadayadayada. Because gas giants have violent storms. (except for saturn) So it began when jupiter just formed. It didn't have its rings just yet. It was the first planet in our solar system! And yes it had a storm when it formed. The storm is called "The great red spot" and jupiter is famous for it.
