The stratospheric polar vortex and sudden stratospheric warmings [PDF]
Weather, 2020 The polar vortex is the dominant feature of the wintertime stratosphere. Sometimes, it is unusually strong, while at others it is very weak or destroyed in an event known as a sudden stratospheric warming (SSW). Both can play an important role in driving the type and predictability of the weather we experience at the surface.

Equatorial counter electrojets and polar stratospheric sudden warmings – a classical example of high latitude-low latitude coupling? [PDF]
Annales Geophysicae, 2009 Favored occurrences of Equatorial Counter Electrojets (CEJs) with a quasi 16-day periodicity over Trivandrum (8.5° N, 76.5° E, 0.5° N diplat.) in association with the polar Stratospheric Sudden Warming (SSW) events are presented.

A Continuum of Sudden Stratospheric Warmings
Journal of the Atmospheric Sciences, 2009 Abstract The k-means cluster technique is used to examine 43 yr of daily winter Northern Hemisphere (NH) polar stratospheric data from the 40-yr ECMWF Re-Analysis (ERA-40). The results show that the NH winter stratosphere exists in two natural well-separated states.

The role of convective overshooting clouds in tropical stratosphere–troposphere dynamical coupling [PDF]
Atmospheric Chemistry and Physics, 2015 This paper investigates the role of deep convection and overshooting convective clouds in stratosphere–troposphere dynamical coupling in the tropics during two large major stratospheric sudden warming events in January 2009 and January 2010.

The Major Sudden Stratospheric Warming Impact on Mid-Latitude Surface Weather [PDF]
EPJ Web of Conferences, 2020 The possible relation of a major sudden stratospheric warming (SSW) with the mid-latitude surface weather conditions was investigated using data from the ERA-Interim and NCEP–NCAR reanalyzes.

Defining Sudden Stratospheric Warmings
Bulletin of the American Meteorological Society, 2015 Abstract Sudden stratospheric warmings (SSWs) are large, rapid temperature rises in the winter polar stratosphere, occurring predominantly in the Northern Hemisphere. Major SSWs are also associated with a reversal of the climatological westerly zonal-mean zonal winds.

Arctic Stratosphere Dynamical Processes in the Winter 2021–2022
Atmosphere, 2022 The Arctic stratosphere winter season of 2021–2022 was characterized by a stable, cold stratospheric polar vortex with a volume of polar stratospheric clouds (PSC) close to the maximum values since 1980, before the beginning of minor sudden stratospheric

How Sudden Stratospheric Warming Affects the Whole Atmosphere [PDF]
Eos, 2018 High above Earth’s surface, air temperatures occasionally increase suddenly, producing widespread effects on weather, air chemistry, and telecommunications.

Solar-Terrestrial Physics, 2016 We have considered the influence of the January 23–27, 2009 sudden stratospheric warming (SSW) event on HF radio wave propagation in the equatorial ionosphere. This event took place during extremely low solar and geomagnetic activity.

Scaling turbulence drives the general circulation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous
