What is a polar vortex 2021?

Posted by EarthSky Voices in Earth | February 11, 2021. The polar vortex is an enormous, 3-dimensional ring of winds that surrounds the North and South poles during each hemisphere’s winter. The polar vortex influences the jet stream, which can bring cold winter weather to the U.S. and Europe.

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 is the coldest it has ever been in the US?

Lowest Temperatures The lowest temperature ever recorded in the United States was -80 degrees Fahrenheit (-62 degrees Celsius) on January 23, 1971 at Prospect Creek Camp, located near the Arctic Circle along the Alaska pipeline.

How common are polar vortexes?

Polar vortexes are not rare in the United States. But, it is important to remember that not all cold weather is the result of a polar vortex. Although a polar vortex can be pushed south, it typically remains parked in polar regions. It takes pretty unusual conditions for the vortex to weaken or migrate far south.

What does the polar vortex look like?

Sometimes the vortex forms a fairly neat, tight circle, but the vortex is typically irregularly shaped with a number of large meanders in the flow known as longwaves. Regions where the cold air dips southward are known as longwave troughs. Regions where the warm air extends northward are known as longwave ridges.

Will 2020 be a hot year?

The results are finally in: 2020 was one of the hottest years in recorded history, according to data released today by NASA and the National Oceanic and Atmospheric Administration.

How long does a polar vortex 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.

Will we have a polar vortex in 2020?

A stratospheric Polar Vortex has now emerged above the Arctic Circle. It will influence the Winter 2020/2021 weather along with the incoming La Nina and west QBO. The road to the next Winter season is always long and it begins well before the temperatures start to drop.

What was the coldest temperature during the polar vortex?

23, 1971, when the record cold temperature of 80 degrees below zero, according to data from the National Oceanic and Atmospheric Administration’s National Center for Environmental Education. The coldest-ever continental U.S. temperature was minus 70 on Jan. 20, 1954, in Rogers Pass, Montana.

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 spring 2020 so cold?

Some studies indicate that the polar jet stream has weakened over the past three decades — which means that the cold surface air from high latitudes increasingly makes it down to middle latitudes. There are also some signs that the Arctic polar vortex, driven by climate change, is also weakening and shifting.

How often does polar vortex happen?

Such stratospheric warming events are common, but major disruptions like that one typically only happen about every other year, says Judah Cohen, the director of seasonal forecasting at Atmospheric and Environmental Research, a company that advises government agencies and the private sector on weather risks.

How cold was it during the polar vortex?

The coldest wind chill was −66 °F (−54 °C) recorded at Ponsford.

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.
