Potential for disrupted polar vortex in January 2024

Potential for disrupted polar vortex in January 2024

Current forecasts indicate a strong Stratospheric Warming event in January 2024, potentially leading to a weakened Polar Vortex and a significant weather pattern shift across the United States and Europe.

Polar vortex forming over North Pole: What it means for winter 2023/24

As the winter season of 2023/2024 approaches, a newly forming Polar Vortex is drawing attention in the Stratosphere over the North Pole. Its rapid intensification could lead to significant weather impacts for parts of North America and Europe.

Stratospheric temperature rise signals weakened polar vortex and Arctic air outbreaks in the northern hemisphere

Stratospheric temperature rise signals weakened polar vortex and Arctic air outbreaks in the northern hemisphere

The polar vortex, a large area of low pressure in the upper atmosphere that typically sits over the poles, is set to weaken as a sudden stratospheric warming (SSW) event unfolds in the northern hemisphere. This event has the potential to have a significant impact on winter weather, as it allows cold Arctic air to escape and cause outbreaks in Europe, Asia, Canada, and the United States.

Europe braces for significant continent-wide cold outbreak

Europe braces for significant continent-wide cold outbreak

After the Sudden Stratospheric Warming (SSW) event at the beginning of January 2021 and the Polar Vortex collapse, weather patterns across the northern hemisphere became very dynamic and progressive. This has set the stage for a potentially quite significant cold…

Sudden Stratospheric Warming (SSW) event started over the weekend

Sudden Stratospheric Warming (SSW) event started over the weekend

A Sudden Stratospheric Warming event started over the weekend in association with a significant weakening or reversal of westerly winds circulating around the North Pole — between 10 and 50 km (6 – 31 miles) above the ground — the stratospheric polar vortex. …

Major Sudden Stratospheric Warming (SSW) event expected as we enter 2021

Major Sudden Stratospheric Warming (SSW) event expected as we enter 2021

A major Sudden Stratospheric Warming (SSW) event is predicted to occur as we start the new year. If the models are correct, we can expect prolonged extremely cold temperatures to affect parts of the northern hemisphere by mid-January. SSW refers to a rapid rise in…

Potential major stratospheric warming event

Potential major stratospheric warming event

Forecast models suggest a major stratospheric warming event might develop in December 2019, possibly initiating a collapse sequence of the polar vortex. Main cooling effects are expected across Eurasia and the United States. "This might have important…

Sudden Stratospheric Warming (SSW) event in progress over the South Pole

Sudden Stratospheric Warming (SSW) event in progress over the South Pole

Sudden Stratospheric Warming (SSW) event is in progress over the South Pole, with temperatures rising more than 40 °C (72 °F) above normal. "These events are significant, as the warming and the disruption of the polar vortex eventually makes its way…
