Sentences with phrase «cyclones over the poles»

Not exact matches

Juno found cyclones as big as 870 miles (1,400 km) in diameter swirling over Jupiter's north and south poles, shows the research published in this week's issue of the journal Science.

The researchers also cite previous research showing that over the past 30 years, the location where tropical cyclones reach their maximum intensity has shifted away from the equator and toward the poles.

Previous surveys by Cassini have found that winds whip through the atmosphere over Saturn's north pole at more than 500 kilometers per hour — 30 percent faster than any gust ever recorded in a cyclone on Earth.

In a paper published today in the journal Nature Geoscience, atmospheric scientists at MIT propose a possible mechanism for Saturn's polar cyclones: Over time, small, short - lived thunderstorms across the planet may build up angular momentum, or spin, within the atmosphere — ultimately stirring up a massive and long - lasting vortex at the poles.

«This mechanism means that little thunderstorms — fast, abundant, but not very strong thunderstorms — over a long period of time can actually accumulate so much angular momentum right on the pole, that you get a permanent, wildly strong cyclone.»

Like a compact series of cogs in an unimaginably large machine, vast cyclones also swirl around the north and south poles, clocking wind speeds of over 220 miles per hour (350 kilometers per hour)-- wind speeds that are the equivalent of a terrestrial Category 5 hurricane.

Here's another finding, courtesy of Juno: Unlike Saturn's enigmatic hexagonal (six - sided polygon) cloud structure over the ringed gas giant's north pole, Jupiter's northern cyclones form an octagonal (eight - sided) grouping.

«Now, with Juno flying over the poles at a close distance it permits the collection of infrared imagery on Jupiter's polar weather patterns and its massive cyclones in unprecedented spatial resolution.»
