10 Day Weather Explainers A Polar Vortex Weakening May Lie Ahead. Here's What That Could Mean The Rest Of This Winter. By Jonathan Erdman December 28, 2023 At a Glance A wrinkle in the winter. 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.
What’s going on with the polar vortex, and is an Arctic outbreak on the
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. 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].

(WeatherBell) Temperatures at the high altitudes above the North Pole are soaring, jumping up to 50 degrees in barely a week. The so-called "sudden stratospheric warming" is disturbing the. SSW phenomenon is linked to polar vortex, an area of low pressure across the North Pole. Meanwhile, Argentina has been gripped by a heatwave Fri 17 Feb 2023 04.38 EST There has been keen interest. A sudden stratospheric warming event may disrupt the polar vortex Feb 10, 2023 - Energy & Environment An event high above the Arctic may turn winter sharply colder in U.S., Europe Andrew Freedman , author of Axios Generate Air temperature anomalies in the stratosphere Feb. 17 as simulated by the American GFS ensemble. Image: WeatherBell.com 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.

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. Sudden Stratospheric Warming becoming likely, could slip us back into winter Publish Dates: 06 Feb 2023 Sources: Michigan Live (Mark Torregrossa) Resource Link: https://www.mlive.com/weather/2023/02/sudden-stratospheric-warming-becoming-likely-could-slip-us-back-into-winter.html
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 warmings (SSWs), breakdowns of the winter stratospheric polar vortex, are one such event.. (2023) Extreme stratospheric wave activity as harbingers of cold events over.
Sudden stratospheric warming takes place, with signs of UK cold on horizon
Published December 5, 2023 Comments: 65 We are excited to announce that NOAA Climate.gov, home of the highly popular ENSO Blog, is venturing into a colder, darker, and windier corner of the atmosphere with the new Polar Vortex Blog. 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.
