The winds at Jupiter’s surface, some of the most powerful in the solar system, influence the planet’s gravitational field, the latest observations show. This means that Jupiter’s signature, crisscrossing bands don’t just exist on the surface of the atmosphere. Jupiter’s wind flows actually extend 3,000 kilometres (about 1,860 miles) below the cloud tops, where the pressure is about 100,000 times that of the atmosphere at Earth’s surface.
