Possible influence of sudden stratospheric warmings on the atmospheric environment in the Beijing–Tianjin–Hebei region [PDF]
Using European Centre for Medium-Range Weather Forecasts fifth-generation (ERA5) and second Modern-Era Retrospective analysis for Research and Applications (MERRA-2) reanalysis and surface meteorological observation data, this study explores the possible

Identifying Perturbations That Tipped the Stratosphere Into a Sudden Warming During January 2013
We present a new methodology demonstrating that specific small‐magnitude regional perturbations can cause large systematic responses in subseasonal predictions.

Arctic Stratosphere Dynamical Processes in the Winter 2021–2022
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

The present study investigates the ionospheric F‐layer scintillation responses in the American sector (90°W–0°, ±50° dip latitude) during the Northern Hemisphere winter sudden stratospheric warming events of 2007–2008, 2008–2009, 2009–2010, and 2012–2013.

Stratosphere-troposphere coupling during stratospheric extremes in the 2022/23 winter
Using the ERA5 reanalysis, sea surface temperature, sea ice observations, and the real-time multivariate Madden-Julian Oscillation (MJO) index, the evolution of the stratospheric extreme circulation in the winter of 2022/2023 is explored.

The Major Sudden Stratospheric Warming Impact on Mid-Latitude Surface Weather [PDF]
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.

Equatorial counter electrojets and polar stratospheric sudden warmings – a classical example of high latitude-low latitude coupling? [PDF]
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.

Abstract The influence of stratospheric processes on the troposphere is defined by a multifactorial mechanism containing various geophysical and photochemical processes. This interaction determines the weather and climate of a particular region of the Earth.

Variability of MLT winds and waves over mid-latitude during the 2000/2001 and 2009/2010 winter stratospheric sudden warming [PDF]
The mesosphere and lower thermosphere (MLT) wind structure over Wuhan (30° N, 114° E) in 2000/2001 winter and over Langfang (39.4° N, 116.6° E) in 2009/2010 winter are examined to reveal the effects of stratospheric sudden warming (SSW) in mid-low ...

Mesosphere and lower thermosphere temperature anomalies during the 2002 Antarctic stratospheric warming event [PDF]
We present kinetic temperatures at ~87 km and ~94 km altitudes inferred from OH (6,2) and O2 At(0,1) airglow observations, respectively, at South Pole (90° S), Antarctica in the austral winter of 2002.
