Jupiter's counter-flowing winds

Jupiter

. Fig. 3.6. Jupiter's counter-flowing winds. The rapid rotation of Jupiter has pulled its winds into bands that flow east to west and west to east, shown in this image taken from the Cassini spacecraft in 2001. The windswept clouds therefore move in alternating light-colored, high-pressure zones and dark-colored, low-pressure belts. The Great Red Spot swirls in the counter-clockwise direction, like a high-pressure cyclone in the Earth's southern hemisphere (Fig. 3.2), but it has lasted for more than 300 years, much longer than terrestrial storms.
