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...

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. ...

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...

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...

Very rare Sudden Stratospheric Warming (SSW) event continues unfolding above the South Pole. This SSW could go down in history as the strongest warming event on record, NIWA said, adding there is increased risk for southerlies in New Zealand into October. SSW...

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...

A rare weather phenomenon for the southern hemisphere - Sudden Stratospheric Warming (SSW) - is amassing in the polar stratosphere. This may lead to unusual or extreme weather in parts of the southern hemisphere (potentially New Zealand) during September and October...

Following the occasional colder snap so far this winter, there are now signs that cold winter weather resulting from a sudden stratospheric warming (SSW) is on the way for the UK, the UK Met Office said January 11, 2019. Sudden stratospheric warming started around...
January 11, 2019
A major Sudden Stratospheric Warming (SSW) event is currently underway in the stratosphere above the Arctic. While not every SSW event is the same and it takes some time for it to show its effects in the troposphere, meteorologists say we can expect colder air move...

At least 11 people have been found frozen to death across Europe over the past couple of days as very cold Arctic air engulfed the continent. This event is its peak today and is currently producing below freezing daytime temperatures across entire Europe except for...

A blast of increasingly cold Arctic air, dubbed 'Beast from the East,' is arriving to Europe and is expected to hang over a large part of the continent through February and engulf all of it from March 5 for at least a couple of days. Very cold Arctic air...
February 20, 2018
Recent Sudden Stratospheric Warming (SSW) event above the North Pole is about to channel in very cold Arctic air into large parts of Europe starting early next week. Very cold weather could extend into early March. "Global models are trending into a powerful...

On February 7, 2018, the Copernicus Atmosphere Monitoring Service or CAMS, has successfully predicted the appearance of an ozone mini-hole over western Canada on February 12 or 13. Sudden stratospheric warmings like the one currently in progress have been shown to...
February 15, 2018
Weather models are suggesting a very high probability of a rare North Pole weather phenomenon called Sudden Stratospheric Warming (SSW) taking place later this month and bringing prolonged bitterly-cold temperatures to the United Kingdom and parts of Europe. Such...
February 08, 2018
Meteorologists from the UK Met Office have predicted a sudden stratospheric warming (SSW) will occur in early March 2016. The phenomena could affect the surface weather, increasing the risk of prolonged wintry conditions over parts of northern Europe and the UK. The...
