The role of wave–wave interactions in sudden stratospheric warming formation [PDF]
Weather and Climate Dynamics, 2020 The effects of wave–wave interactions on sudden stratospheric warming formation are investigated using an idealized atmospheric general circulation model, in which tropospheric heating perturbations of zonal wave numbers 1 and 2 are used to produce ...

Oceanic fronts shape hemispheric contrasts in polar stratospheric extremes [PDF]
Nature CommunicationsSudden Stratospheric Warmings (SSWs) and Polar Stratospheric Clouds (PSCs) exhibit striking inter-hemispheric asymmetries: SSWs are frequent in the Arctic but rare in the Antarctic, while PSCs are more persistent in the Antarctic.

The sudden stratospheric warming in January 2021
Environmental Research Letters, 2021 Using the ERA5 reanalysis, sea surface temperature and sea ice observations, and the real-time multivariate Madden–Julian index, this study explores a sudden stratospheric warming (SSW) in January 2021, its favorable conditions, and the near surface ...

Stratospheric impacts on Eurasian soil moisture on subseasonal timescales [PDF]
Nature CommunicationsSudden stratospheric warming (SSW) events and soil moisture are both key sources of subseasonal-to-seasonal predictability, raising the possibility that SSWs could enhance hydroclimate predictability through soil moisture.

Local and remote response of ozone to Arctic stratospheric circulation extremes [PDF]
Atmospheric Chemistry and Physics, 2021 Intense natural circulation variability associated with stratospheric sudden warmings, vortex intensifications, and final warmings is a typical feature of the winter Arctic stratosphere.

Stratosphere-troposphere coupling during stratospheric extremes in the 2022/23 winter
Weather and Climate Extremes, 2023 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.

Influences of Sudden Stratospheric Warming Events on Tropopause Based on GNSS Radio Occultation Data
Atmosphere, 2023 Sudden Stratospheric Warming (SSW) events have a strong impact on the tropospheric weather and climate. Past researchers have carried out extensive studies investigating the theories of interactions between the stratosphere and the troposphere.

Tropospheric forcing of the boreal polar vortex splitting in January 2003 [PDF]
Annales Geophysicae, 2010 The dynamical evolution of the relatively warm stratospheric winter season 2002–2003 in the Northern Hemisphere was studied and compared with the cold winter 2004–2005 based on NCEP-Reanalyses.

Identifying Perturbations That Tipped the Stratosphere Into a Sudden Warming During January 2013
Geophysical Research Letters, 2023 We present a new methodology demonstrating that specific small‐magnitude regional perturbations can cause large systematic responses in subseasonal predictions.
