   Feb 3, 2014 · A vortex ring is a doughnut-shaped phenomenon where fluids or gases knot and spin in a closed, usually circular loop. The physics of vortex rings is the same as that which gives stability to tornadoes, volcanic eruptions and mushroom clouds.

   Jan 7, 2014 · The oval shape of Mars' north polar vortex is referred to as a "wave-2 type" structure. What does that mean? If you projected the photo I show above in a cylindrical projection, the north polar vortex would look like a wavy horizontal band, with two peaks and two valleys.

   May 21, 2024 · A blob-like shape centered roughly on the North Pole, with cold (blue) air inside and warm (red) air outside: A warming Arctic produces a weaker jet, more likely to bend off course. This wavy pattern can shift the boundary between cold Arctic air and warm mid-latitude air to strange places.

   Sep 3, 2020 · But Irvine threw two new factors into the mix: “writhing” and “twisting.” Imagine a straight length of hose, representing the length of a straight vortex like a tornado. Writhing reflects the hose taking on a wriggly shape, like that of a Slinky, or in a more extreme case becoming coiled.

   Dec 21, 2022 · So meteorologists are watching both of those layers, the stratosphere and the troposphere, but when you hear “polar vortex,” it’s usually referring to that well defined area of low pressure that’s typically over or near the North Pole, about 10 to 30 miles above the surface in the stratosphere.

   Mar 24, 2022 · A new type of high-frequency acoustic wave discovered propagating on the Sun seems to be defying expectations. The waves appear on the surface of the Sun as a pattern of swirling vortices, moving against the Sun's rotation.

   What is a polar vortex?

   • Bob Henson: When you hear the phrase “ polar vortex,” it’s usually referring to the North Pole and we’re talking about Northern Hemisphere winter weather. So this is an area of low pressure up in the stratosphere, usually centered near the North Pole. It can slosh around, it can stretch, and it can break into two pieces.

   How many polar vortexes are there?

   • 2 As with the polar jet stream, there are actually two polar vortexes, one on the North and one on the South Pole. The polar jet stream and polar vortex are two rings of fast-moving air around the Arctic, which, as the climate warms, may change in ways that cause some places to see more extreme cold spells during winter.

   Does polar vortex distortion weaken the jet stream to the south?

   • Either distortion tends to weaken the jet stream to the south. There have been recent spectacular examples of polar vortex breakdowns leading to extreme winter storms—like an event in January and February 2019 that broke cold temperature records across the eastern U.S. and Canada.

   What is a vortex ring?

   • A vortex ring is a doughnut-shaped phenomenon where fluids or gases knot and spin in a closed, usually circular loop. The physics of vortex rings is the same as that which gives stability to tornadoes, volcanic eruptions and mushroom clouds. ( Dolphins actually create their own vortex rings in water for entertainment.)
