'Sudden Stratospheric Warmings' in 2023 could trigger winter

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?

Major Warming Disrupts Polar Vortex Cold West, 6 Weeks of Extreme WX for U.S. Ahead

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).

A Sudden Stratospheric Warming is coming, collapsing the Polar Vortex and potentially impacting

The Sudden Stratospheric Warming event (SSW) has left a strong mark on the Polar weather circulation and the atmosphere. As a result, a significant high-pressure blocking system is building over Greenland and will impact the entire North American region and Europe in the coming weeks.. El Nino event signal is getting stronger for 2023. When.

Sudden Stratospheric Warming Universal Group Of Institutions

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).

'Polar vortex' may blanket US with arctic weather in January WTTE

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.

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 Warmings' in 2023 could trigger winter

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

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.

Winter 2023/24 Chat and Discussion Page 91  Winter Weather Discussion

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.

Major sudden stratospheric warming likely, raising risk of severe UK cold

What’s going on with the polar vortex, and is an Arctic outbreak on the

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.
