Kate Middleton and Prince William's 'stark contrast' to Prince Harry
Sudden stratospheric warming events can be caused by large atmospheric waves in either the stratosphere or the troposphere. Planetary waves have ridges and troughs like ocean waves, but span huge distances in the atmosphere. And just like waves crash at the beach, atmospheric waves can "crash" too, both in the horizontal and vertical directions.

2.3 Specification of Sudden Stratospheric Warming and Final Warming Events We identify SSW events that occurred in the real atmosphere using the criterion from Charlton and Polvani ( 2007 ), who specify the SSW onset day via the reversal of the zonal mean zonal wind at 60°N and 10 hPa ( , a measure for the polar vortex strength).

Will a Sudden Stratospheric Warming Event Save a SnowStarved North
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 Warmings' in 2023 could trigger winter
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).
Sudden stratospheric warming takes place, with signs of UK cold on horizon
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?
What’s going on with the polar vortex, and is an Arctic outbreak on the
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.
'Sudden Stratospheric Warmings' in 2023 could trigger winter
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.
Major Warming Disrupts Polar Vortex Cold West, 6 Weeks of Extreme WX for U.S. Ahead
» 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
'Polar vortex' may blanket US with arctic weather in January WTTE
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.
Met Office verdict on 'Beast from the East snow blast' tipped to return
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 Universal Group Of Institutions
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.
