Why do some planets have stripes?

Certain gas worlds like Jupiter, is covered by strips parallel to the surface Ecuador occupying one pole to another. In these regions, the winds flow at different speeds. Astronomers assumed that originated by a phenomenon of convection, which arose as a result of the tendency of heat to rise and fall of the cold, but it was unclear if only taking place in the atmosphere or if they reached the planet's core .

Now a team of researchers from the universities of Göttingen, Germany, and Aix-Marseille, France, has proposed that these may also originate in part by the gravitational pull of the dozens of moons of the gas giant
