Possible Causes of the Occurrence of a Rare Antarctic Sudden Stratospheric Warming in 2019

Atmosphere, 2022
A minor Antarctic sudden stratospheric warming (SSW) with the strongest circulation changes since the first major SSW over the Antarctic was recorded in 2002 occurred in early September 2019.

A Minimal, Adiabatic Example of Sudden Stratospheric Warming

Journal of Advances in Modeling Earth Systems
Sudden Stratospheric Warming (SSW) are extreme weather events that can significantly impact weather patterns on short to subseasonal to seasonal timescales. In this study, we present a new idealized test case of a Sudden Stratospheric Warming (SSW) event

An Explanation of the Poleward Mass Flux in the Stratosphere

Atmosphere
This paper offers a new perspective on the explanation of the poleward mass flux in the stratosphere. This mass flux represents the upper leg of the so-called Brewer–Dobson circulation. This new perspective is based on the following hypothesis.

Influence of stratospheric sudden warming on the tropical intraseasonal convection

Environmental Research Letters, 2020
Madden–Julian oscillation (MJO), the dominant mode of intraseasonal variability in the tropical troposphere, has recently been shown to have a great impact on Northern Hemisphere (NH) extratropical stratosphere.

Surface hazards in North-west Europe following sudden stratospheric warming events

Environmental Research Letters, 2023
Sudden stratospheric warmings (SSWs) have been linked to surface temperature anomalies, but how these connect to changes in the likelihood of specific weather extremes and their associated weather patterns remains uncertain. While, on average, it is true

Impact of Sudden Stratospheric Warmings on the Stratosphere-to-Troposphere Transport of Ozone

Geophysical Research Letters
not-yet-known not-yet-known not-yet-known unknown Sudden stratospheric warmings (SSWs) can significantly impact tropospheric weather systems. Previous studies suggest that SSWs may also influence stratosphere-to-troposphere transport (STT), but their spatial and temporal distribution and

Response of Total Column Ozone at High Latitudes to Sudden Stratospheric Warmings [PDF]

, 2023
The total column ozone (TCO) at northern high latitudes is increased over a course of 1–2 months after a major sudden stratospheric warming as a consequence of enhanced ozone eddy transport and diffusive ozone fluxes.

Arctic sea ice decline, increasing successive sudden stratospheric warmings and cold northern hemisphere continents

Communications Earth & Environment
The frequency of successive sudden stratospheric warming events has markedly increased since 2000s. Using multimodel experiments it is demonstrated that reduced sea ice leads to higher frequencies of successive warming events.

Ozone Changes Due To Sudden Stratospheric Warming‐Induced Variations in the Intensity of Brewer‐Dobson Circulation: A Composite Analysis Using Observations and Chemical‐Transport Model

Geophysical Research Letters, 2023
We quantify the changes in the intensity of Brewer‐Dobson Circulation (BDC) during sudden stratospheric warming (SSW) and its impact on the tropical stratospheric thermal structure and ozone distribution by composite analysis using observations and a ...

STRATOSPHERIC SUDDEN WARMING IN 1989 FROM THE VIEWPOINT OF ATMOSPHERIC ANGULAR MOMENTUM [PDF]

, 1997
P(論文)A major wavenumber-2 stratospheric sudden warming occurred in mid-February of 1989. Using the U. S. National Meteorological Center (NMC) data, an analysis of this event was performed based on the angular momentum equation in the transformed Eulerian-
