10-15 day forecast: The tropospheric polar vortex breaks down, releasing colder weather down into the United States and Northern Europe

A massive advance of high-pressure systems over the North Pole will help to break down the usual jet stream flow of the polar vortex. The …

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. One of the major drivers …

Sunlight has reached the stratosphere over the South Pole. Combined with the polar stratospheric clouds, the ozone destruction process has now begun, creating an ozone …

Rare event A rare Ozone hole develops over the Arctic/Canadian region, unusually strong for the Northern Hemisphere!

It is a rather rare occurrence to see a larger area of sustained ozone depletion over the Arctic regions during the late winter/early spring season. …

Stratospheric Final Warming The unusually strong Polar Vortex is awaiting judgment! A bi-modal warming wave develops, which could initiate the Final Warming collapse sequence

Every year, a final warming event occurs in the stratosphere, as we head into spring, and the Sun starts warming up the polar regions. Sometimes …

Uncertainties arise for Spring 2020, as the Polar Vortex starts to behave unusually. It turns bizarrely symmetrical and also cold enough to start the rare Ozone destruction process over the North Pole!

We have talked a lot about the polar vortex this season, and its powerful run, which is far from over. Recently, the lower part of …

Stratospheric warming UPDATE The warming phase is about to start this week. It will compress the Polar Vortex, reduce the core power and disconnect it from the troposphere!

The new stratospheric warming phase is set to start this week. It will greatly reduce the strength of the stratospheric polar vortex. Considering that we …

Stratosphere watch A double stratospheric warming wave is starting to develop for the next two weeks, which could have implications for late February and Spring weather patterns!

The polar vortex usually reaches its peak strength in late December and early January. As we head further into January and February, the Polar Vortex …
