Weather in the North Pole of Saturn



Saturn’s rings are famous, and People are attracted by the mystery on the Solar System’s second-largest planet. From 1610, when Galileo used his primitive telescope to spot what looked like bumps protruding from either side of Saturn, to today when modern telescopes and space probes and aircrafts are created to assist unveil what’s on Saturn.

Like Earth, Saturn is surrounded by wide atmospheric gases, compared with which the solid core is so small. An those atmospheric gases, driven by powerful winds, organize themselves into massive storms which can last for decades, or even centuries.

However, when observer show what is on Saturn’s north polar, even experienced Saturn-watchers did a double-take. It is storm, which is so gigantic that it could swallow Earth, with room to spare. The eye alone is more than 1,200 miles (1,900 km) across, and wind speeds at the vast cyclone’s outer edges reach 330 mph (531 k/h).

the storm is far bigger and more powerful than anything Earth has ever experienced. it’s structurally similar to the hurricanes that batter the U.S. and Caribbean islands every year. What’s markedly different is that those storms move across the planet; Saturn’s polar storm just sits at the top of the globe without budging. That’s not because the dynamics of Saturn’s atmosphere are fundamentally different from those of Earth: the giant planet has jet streams and prevailing winds just as we do.
