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.
How often do polar vortexes 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 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.
Does the polar vortex happen every year?
The Short Answer:
This happens fairly regularly and is often associated with outbreaks of cold temperatures in the United States. If you’ve heard of a polar vortex, you might know it has something to do with very cold weather.
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.
Is it going to be a early spring 2020?
The vernal equinox will take place on March 19 throughout the entire United States including Alaska and Hawaii, almost 18 hours ahead of when the vernal equinox occurred in 2019. Moreover, the 2020 equinox will have arrived earlier than any other equinox in the last 124 years.
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 cold is a polar vortex?
The winds of winter
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.
What does a 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.
What is the coldest earth has ever gotten?
The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
What states will the polar vortex hit?
Polar vortex set to unleash Arctic blast on huge swath of US. Freezing temperatures will hit states ranging from Texas to Washington, D.C.
Why is the polar vortex so dangerous?
A Polar Vortex is a pattern of winds that rises in the Arctic resembling cyclones that flows around the North Pole year round. 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.
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.
Why is polar wind cold?
But even during the polar day, the period of continuous sunlight, only a relatively small amount of solar energy reaches the Arctic or Antarctic regions due to the low angle of incoming rays. These two phenomena thus form the basis for sustained cold conditions in the northern and southern polar regions.
How do you prepare for a polar vortex?
Preparing your vehicle for the freezing weather of a polar vortex
- Make sure your tires are properly inflated.
- Check your tire tread.
- Check your brakes.
- Check your windshield wiper blades.
- Replace wiper fluid with low-temperature fluid.
- Check engine coolant and antifreeze levels.
- Keep your gas tank full.
