The Sudden Stratospheric Warming Events in the Antarctic in 2024

Geophysical Research Letters
In July and August 2024, two consecutive stratospheric sudden warming (SSW) events (termed SW07 and SW08) occurred over Antarctic, both featuring a rapid 17°C temperature rise at 10 hPa and significant stratospheric polar vortex (SPV) deceleration.

Understanding the Response of the Quasi‐Biennial Oscillation to Carbon Dioxide and Sea Surface Temperature Increases in Aqua‐Planet Simulations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) of the tropical stratospheric zonal winds influences tracer transport, the stratospheric polar vortex, and extra‐tropical surface variability. However, the response of the QBO to increasing greenhouse gas concentrations is still uncertain.

Dynamical Precursors for Statistical Prediction of Stratospheric Sudden Warming Events

Geophysical Research Letters, 2018
This work explores dynamical arguments for statistical prediction of stratospheric sudden warming events (SSWs). Based on climate model output, it focuses on two predictors, upward wave activity in the lower stratosphere and meridional potential ...

Optimizing the Definition of a Sudden Stratospheric Warming

Journal of Climate, 2018
AbstractVarious criteria exist for determining the occurrence of a major sudden stratospheric warming (SSW), but the most common is based on the reversal of the climatological westerly zonal-mean zonal winds at 60° latitude and 10 hPa in the winter stratosphere. This definition was established at a time when observations of the stratosphere were sparse.

Analysis of gravity wave activity during stratospheric sudden warmings in the northern hemisphere

Earth and Planetary Physics
Due to the significant changes they bring to high latitude stratospheric temperature and wind, stratospheric sudden warmings (SSWs) can have an impact on the propagation and energy distribution of gravity waves (GWs). The variation characteristics of GWs
