A Sudden Stratospheric Warming is coming, collapsing the Polar Vortex and potentially impacting
Sudden stratospheric warmings (SSWs), breakdowns of the winter stratospheric polar vortex, are one such event.. (2023) Extreme stratospheric wave activity as harbingers of cold events over.
Winter 2023/24 Chat and Discussion Page 91 Winter Weather Discussion
Stratospheric sudden warmings (SSWs) are global-scale meteorological events driven by the dissipation of vertically propagating planetary waves originating in the troposphere (Butler et al., 2015; Matsuno, 1971). SSW events are characterized based on the changes that occur in the stratosphere, including a rapid increase in polar temperatures.
Sudden Stratospheric Warming Likely, What Does it Mean For Our Weather? CW Weather
Sudden stratospheric warming (SSW) describes an atmospheric-variability phenomenon at a daily-to-monthly scale where temperature in the middle stratosphere (about 30 km or 10 hPa) increases rapidly ( >30 to 40 K) within a couple of days in sub-polar and polar regions (McInturff, 1978; Butler et al., 2015; Baldwin et al., 2020).

» Yale Climate Connections Eye on the Storm How will El Niño affect the U.S. this winter? Strong El Niño events like this one have classic calling cards, but surprises still happen — especially on a warming planet. by Bob Henson December 12, 2023
Major sudden stratospheric warming likely, raising risk of severe UK cold
Abstract In this investigation, a comparison is presented between variations in temperature and ozone concentration at different altitude levels in the stratosphere for the Northern Hemisphere in the conditions of Sudden Stratospheric Warming (SSW) for the period January-March 2023.
Will a Sudden Stratospheric Warming Event Save a SnowStarved North
Other times, the vortex winds "break down" and reverse direction entirely (aka "sudden stratospheric warming"). However, not every weakening of the vortex or warming over the Arctic can be considered a so-called "major" warming event. Those typically happen once every year or two [footnote #2]. What's your communication style?

The winter of 2023-24 has suddenly shifted from being delayed,. This culminated in what is known as a "Sudden Stratospheric Warming" event around Jan. 6, she told Axios. Rapidly increasing temperatures at around 100,000 feet disrupted the vortex's circulation. This warming event, has helped to reinforce an area of high pressure over.
New Year 2024 news World 2024 with a bang as Sydney
The sudden stratospheric warming event was kicked into gear by planetary waves, or disturbances, in both the troposphere and stratosphere, noted polar vortex experts Amy Butler of NOAA's Chemical Sciences Laboratory and Laura Ciasto of NOAA's Climate Prediction Center.
Strat Watch Will We Get A Sudden Stratospheric Warming For Winter 2023
When we last wrote two weeks ago, the forecasts suggested that the stratospheric polar vortex would continue to weaken and warm into January. Though there were a few days around the end of December where forecasts moved closer to predicting a full reversal of the west-to-east vortex winds that comprise a major "sudden stratospheric warming", the ingredients did not fully come together.

‘Sudden stratospheric warming’ could make for more bitter cold, winter weather chances down the road
The "warming" refers to the dramatic increase in temperature (~50-70 degrees F in a few days!) over the polar stratosphere during these events (see the figure below). These events occur roughly every other year in the Northern Hemisphere.
