Polar vortex. It's a phrase that becomes very popular has achieved buzzword status and is often used frequently during the winter as the Northern Hemisphere endures its coldest months of the year ...
Zooplankton, for example, grow to a larger body size and produce larger eggs in greater numbers than in other regions. [2]: 42–43 Aside from the polar desert conditions of much of the island, there are remarkably productive ecological zones in the arctic oasis of the Lake Hazen area and the polynyas of the island's coastal waters.

Hearing about the polar vortex in May is a little bit like running into your dentist at the circus, so don’t feel bad if you need a reminder of how it all works.
Prior to the events of January 2014, several studies on the connection between extreme weather and the polar vortex were published suggesting a link between climate change and increasingly extreme temperatures experienced by mid-latitudes (e.g., central North America). [89]
On December 6, the continued deterioration of the polar vortex led to the jet stream pushing southward, bringing record cold temperatures across the Eastern U.S. During the cold wave, which extended from December 6–10, over 150 daily precipitation records [ 24 ] and close to 100 daily snowfall records were broken across the northeastern ...
In late January 2019, a severe cold wave caused by a weakened jet stream around the Arctic polar vortex [5] hit the Midwestern United States and Eastern Canada, killing at least 22 people. [3] [4] It came after a winter storm brought up to 13 inches (33 cm) of snow in some regions from January 27–29, and brought the coldest temperatures in ...
Northern lights activity on rise amid solar maximum The aurora borealis, a natural light display in Earth's sky famously best seen near our planet's poles, spent 2024 cropping up in a wider swath ...
The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex. The stratospheric and tropospheric polar vortices both rotate in the direction of the Earth's spin, but they are distinct phenomena that have different sizes, structures, seasonal cycles, and impacts on weather.
