1 : something that resembles a whirlpool the hellish vortex of battle — Time. 2a : a mass of fluid (such as a liquid) with a whirling or circular motion that tends to form a cavity or vacuum in the center of the circle and to draw toward this cavity or vacuum bodies subject to its action especially : whirlpool, eddy.
What is a vortex on Earth?
A vortex is believed to be a special spot on the earth where energy is either entering into the earth or projecting out of the earth’s plane. It is believed that the vortex energy moves in a spiral, moving up or down.
Is a vortex dangerous?
A Polar Vortex is the most dangerous when it weakens as it creates more acute winter conditions and can lead to extreme frigid weather conditions in the eastern U.S. Some are quick to blame this extreme cold on Global Warming and the decline of Arctic Sea Ice.
Is a polar vortex coming 2020?
The Polar Vortex now collapsing, is set to release the Arctic Hounds for the United States and Europe, as we head for the second half of Winter 2020/2021. A Polar Vortex collapse sequence has begun in late December 2020, with a major Sudden Stratospheric Warming event on January 5th, 2021.
The polar vortex and the February 2021 cold extreme in the south-central United States. There is plenty of research linking disruptions of the stratospheric polar vortex to extreme cold air outbreaks in the mid-latitudes of the United States or Eurasia a few weeks later.
What is winter vortex?
The polar vortex is a large area of low pressure and cold air surrounding both of the Earth’s poles. It ALWAYS exists near the poles, but weakens in summer and strengthens in winter. The term “vortex” refers to the counter-clockwise flow of air that helps keep the colder air near the Poles.
Why is the South Pole colder than the North Pole?
Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. The Antarctic is land surrounded by ocean. The ocean under the Arctic ice is cold, but still warmer than the ice!
What is the polar vortex 2021?
Near-surface air temperatures across the Northern Hemisphere from February 15–22, 2021, compared to the 1981-2010 average. The polar jet stream made a deep dive into the south-central United States, bringing extreme cold (dark blue) to the Southern Plains.
The POLAR VORTEX is coming!!!!! — Sudden Stratospheric Warmings (SSWs) are occasions in the winter (~6 times per decade), when the polar stratosphere warms and the winds that normally flow from west to east around the pole weaken dramatically and even reverse direction, corresponding to a breakdown of the polar vortex.
What is a polar vortex 2020?
This year, the polar vortex, which is a large pool of frigid air – typically the coldest in the Northern Hemisphere – that often sits over the polar region during the winter, is forecast to remain strong and hover near the Arctic Circle in the coming weeks.
Why is 2021 so cold?
As with most cold waves, the origins of the cold wave occurred when the jet stream migrated southward in early February 2021, allowing bitterly cold air from the polar vortex to spill south into the Upper Midwest and Great Plains. An arctic front then proceeded to usher in the cold air by February 6.
How cold can a polar vortex get?
In the darkness of the winter polar night, temperatures within the polar vortex can easily get lower than minus 110 F (minus 79 C). Fortunately for everyone, the stratospheric polar vortex itself won’t appear outside your front door.
How long is the polar vortex supposed to last?
Those individual vortices can persist for more than a month. Volcanic eruptions in the tropics can lead to a stronger polar vortex during winter for as long as two years afterwards. The strength and position of the polar vortex shapes the flow pattern in a broad area about it.
Freshen up the smoke and carbon monoxide detectors.
Store a winter survival kit in the trunk of your car.
Keep your drive and walkways clear.
Clear the chimney.
Keep the gas meter clean and dry.
What’s going on with the polar vortex?
So far this year, the polar vortex has shifted off the pole and become very stretched out over the North Atlantic and Europe, though in the lowermost stratosphere some splitting has occurred. In the coming weeks the vortex looks to shift over northern Asia and then possibly become more elongated over North America.
What type of winter is predicted for 2021?
U.S. Winter Weather Forecast 2020-2021 We’re predicting a light winter for most of us here in the United States, with warmer-than-normal temperatures in the forecast for a large part of the country. Uncommonly chilly temperatures will be limited mostly to the western states and northeastern New England.
