Evaluation of the E3SM Version 3 Stratosphere Performance

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract The interactions between the stratosphere and the troposphere have significant impacts on human activities and Earth system variability. In the third release version of the low‐resolution Energy Exascale Earth System Model (E3SMv3), the representation of the stratosphere is improved through vertical grid refinement in the lower stratosphere ...

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.

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.

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 ...

Construction of a Global Atmospheric Refractivity Model for Optical Wavelengths Based on Temporal Evolution Characteristics

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Atmospheric refractivity model accuracy is important for refraction correction, starlight refraction navigation, and related optoelectronic applications. To address the insufficient understanding of refractivity temporal evolution and the lack of clear criteria for selecting model temporal resolution, this study constructs a global four ...

Estimation of Mesoscale Momentum Flux Frequency Spectra in the Mesosphere and Lower Thermosphere Using Multistatic Specular Meteor Radar Wind Fields

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract A spectrally resolved observational methodology is introduced to estimate mesoscale momentum flux frequency spectra in the mesosphere and lower thermosphere (MLT). The method is applied to four‐dimensional wind fields reconstructed with the physics‐informed neural network approach called the Hydrodynamic Point‐wise Environment Reconstructor ...

AI Emulation of Stochastic Sudden Stratospheric Warming With Interpretable Latent Structure

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Rare weather regime transitions pose a challenge for data‐driven modeling due to class imbalance. In this study, we develop a probabilistic deep learning emulator for a prototypical system with regime transitions, the stochastic Holton–Mass (HM) model of stratospheric variability, and analyze the structure of its learned latent space.

The Asynchronous Evolution of Cold Waves Over China Revealed by 3D Spatiotemporal Tracking

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Cold waves pose substantial risks to ecosystems, infrastructure, and society. While most studies have examined their station‐level frequency or regional intensity, the joint behaviors in both time and space remain largely unexplored. Here, we apply a three‐dimensional connected‐component labeling algorithm to daily temperature observations ...

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-
