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

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.

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.

Stratosphere–Troposphere Coupling During Cold Air Outbreaks in the Eastern United States

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Cold air outbreaks (CAOs) are extreme weather events characterized by the equatorward displacement of polar air. This study investigates CAOs occurring along the East Coast of the US and establishes that approximately 16% are driven by stratosphere‐troposphere coupling through wave dynamics.

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, Volume 98, Issue 8, Page 514-524, August 2026.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Overview of Aerosols in the E3SM Version 3: New Model Features and Their Impacts

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Accurate and comprehensive representation of aerosols in Earth system models (ESMs) is critical for modeling radiative forcing and seasonal‐to‐decadal variability. With increasing computing power, detailed physical and chemical processes representing aerosols and their interactions with other components of the Earth system can be treated more ...

Atmospheric Constituent Data Assimilation in NASA's Goddard Earth Observing System

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Many of today's most significant and urgent scientific questions, including those about the impact of human activity on air quality and radiative forcing, require the synthesis of observations of atmospheric constituents and scientific theory.

The preconditioning of major sudden stratospheric warmings [PDF]

Journal of Geophysical Research: Atmospheres, 2012
The preconditioning of major sudden stratospheric warmings (SSWs) is investigated with two long time series using reanalysis (ERA‐40) and model (MAECHAM5/MPI‐OM) data. Applying planetary wave analysis, we distinguish between wavenumber‐1 and wavenumber‐2 major SSWs based on the wave activity of zonal wavenumbers 1 and 2 during the prewarming phase. For

Antarctic Ozone Enhancement During the 2019 Sudden Stratospheric Warming Event

Geophysical Research Letters, 2020
We analyze the 2019 sudden stratospheric warming event that occurred in the Southern Hemisphere through its impact on the Antarctic ozone. Using temperature, ozone, and nitric acid data from the Infrared Atmospheric Sounding Interferometer (IASI), our ...

Ionospheric F‐Layer Scintillation Variabilities Over the American Sector During Sudden Stratospheric Warming Events

Space Weather, 2021
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.
