Limited surface impacts of the January 2021 sudden stratospheric warming [PDF]

open access: yesNature Communications, 2022
Subseasonal weather prediction can reduce economic disruption and loss of life, especially during “windows of opportunity” when noteworthy events in the Earth system are followed by characteristic weather patterns.

The role of convective overshooting clouds in tropical stratosphere–troposphere dynamical coupling [PDF]

open access: yesAtmospheric 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.

Local and remote response of ozone to Arctic stratospheric circulation extremes [PDF]

open access: yesAtmospheric 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.

The role of wave–wave interactions in sudden stratospheric warming formation [PDF]

open access: yesWeather 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 ...

Stratosphere-troposphere coupling during stratospheric extremes in the 2022/23 winter

open access: yesWeather 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.

The sudden stratospheric warming in January 2021

open access: yesEnvironmental 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 ...

Influences of Sudden Stratospheric Warming Events on Tropopause Based on GNSS Radio Occultation Data

open access: yesAtmosphere, 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.

Composite analysis of a major sudden stratospheric warming [PDF]

open access: yesAnnales Geophysicae, 2015
We present the characteristics of a major sudden stratospheric warming (SSW) by using the composite analysis method and ERA Interim reanalysis data from 1979 to 2014.

Atmospheric Circulation Response to Short-Term Arctic Warming in an Idealized Model [PDF]

open access: yes, 2020
Recent Arctic sea ice loss in fall has been posited to drive midlatitude circulation changes into winter and even spring. Past work has shown that sea ice loss can indeed trigger a weakening of the stratospheric polar vortex, which can lead to delayed ...

Tropospheric forcing of the boreal polar vortex splitting in January 2003 [PDF]

open access: yesAnnales 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.
