Wong , Joseph DePasquale It’s so iconic that it’s unusual to see an image of Jupiter without it, despite the fact that Jupiter rotates once in just under 10 hours.A storm roughly the diameter of Earth , the Great Red Spot , is in Jupiter ’s southern hemisphere and has been raging since at least 1831.
“We found through numerical simulations that by feeding the Great Red Spot a diet of smaller storms, as has been known to occur on Jupiter, we could modulate its size,”The work has implications for predicting extreme weather on Earth. High-pressure systems in the westerly jet streams that circulate across Earth’s mid-latitudes—a major factor in heat waves and droughts—may be linked to high-pressure eddies and anticyclones.
“Our study has compelling implications for weather events on Earth,” said Keaveney. “Interactions with nearby weather systems have been shown to sustain and amplify heat domes, which motivated our hypothesis that similar interactions on Jupiter could sustain the Great Red Spot. In validating that hypothesis, we provide additional support to this understanding of heat domes on Earth.”above Jupiter’s “Great Red Spot.
However, since Amalthea takes less than half a day to orbit Jupiter, its temperature could be due to tidal stresses caused by Jupiter’s gravity, which creates a lot of friction and heat within it.Our community is about connecting people through open and thoughtful conversations.
