Is there a polar vortex coming 2021?
Is there a polar vortex coming 2021?
Stratospheric Polar Vortex returns for Winter 2021/2022, together with a strong easterly wind anomaly high above the Equator, impacting the Winter season. A new stratospheric Polar Vortex has now emerged over the North Pole and will continue to strengthen well into the Winter of 2021/2022.
What is a vortex in weather?
The term “vortex” refers to the counter-clockwise flow of air that helps keep the colder air near the Poles. This occurs fairly regularly during wintertime and is often associated with large outbreaks of Arctic air in the United States.
What type of winter is predicted for 2022?
The 2022 Old Farmer’s Almanac comes with a winter warning: Prepare for a “Season of Shivers.” This winter will be punctuated by positively bone-chilling, below-average temperatures across most of the United States.
How is the polar vortex related to climate change?
The change is warming higher latitudes and reducing the temperature difference between the warmer mid-latitude and polar regions. This weakens and destabilizes the polar jet stream, causing it to dip into lower latitudes, bringing polar air farther south.
Will it be a cold winter 2022?
There will be snow and cold temperatures as 2021 comes to an end, and more snow and even colder temperatures as 2022 begins, according to the National Weather Service. And it will get really cold on New Year’s Eve — an overnight low of 11 is expected.
How do jet streams affect climate?
How Do Jet Streams Affect Weather? The fast-moving air currents in a jet stream can transport weather systems across the United States, affecting temperature and precipitation. However, if a weather system is far away from a jet stream, it might stay in one place, causing heat waves or floods.
Is the jet stream changing?
A new study finds that the jet stream could shift outside the bounds of its historic range within just a few decades — by the year 2060 or so — under a strong warming scenario. Many scientists believe rising air temperatures can affect the jet stream’s flow.
Why the polar vortex keeps breaking out of the Arctic?
It’s an area of cold air with low atmospheric pressure over the Arctic. As with all areas with low pressure in the northern hemisphere, the winds of the polar vortex swirl counterclockwise and inward towards the North Pole.
