Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...

The impact of polar stratospheric ozone loss on Southern Hemisphere stratospheric circulation and climate [PDF]

Atmospheric Chemistry and Physics, 2014
The impact of polar stratospheric ozone loss resulting from chlorine activation on polar stratospheric clouds is examined using a pair of model integrations run with the fully coupled chemistry climate model UM-UKCA.

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 ...

An inter‐hemisphere comparison of the persistent stratospheric polar vortex [PDF]

Geophysical Research Letters, 2000
Based on 19 years (1979–1998) of NCEP/NCAR reanalyses data and potential vorticity (PV) area diagnostics, we found that in the southern hemisphere (SH) the polar vortex has lasted about two weeks longer in the 1990s than in the early 1980s and the northern hemisphere (NH) polar vortex has lasted four weeks longer.

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 ...

Intercomparison of Stratospheric Chemistry Models under Polar Vortex Conditions

Journal of Atmospheric Chemistry, 2003
Several stratospheric chemistry modules from box, 2-D or 3-D models, have been intercompared. The intercomparison was focused on the ozone loss and associated reactive species under the conditions found in the cold, wintertime Arctic and Antarctic vortices.

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.

Stratospheric and tropospheric contributions to North American cold temperatures and subsequent North Atlantic jet stream anomalies

Weather and Climate Extremes
Stratospheric variability can modulate tropospheric circulation and surface weather, yet its contribution relative to tropospheric drivers remains difficult to quantify. We address this by applying quantile generalized additive models (QGAMs) to flexibly

Stratospheric response to Arctic sea ice retreat and associated planetary wave propagation changes

Tellus: Series A, Dynamic Meteorology and Oceanography, 2013
The stratospheric response to the observed Arctic sea ice retreat is analysed based on European Centre for Medium-Range Weather Forecast (ECMWF) Re-Analysis Interim (ERA-Interim) atmospheric data from 1979–2012.

Intra‐Seasonal Variability of Serial Clustering of Severe European Winter Windstorms

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Clustering of severe European winter windstorms causes large economic loss and social‐environmental impacts. We present a detailed analysis of the intra‐seasonal variability of clustering of severe European winter windstorms based on ERA5 reanalysis, with the focus on impact‐relevant footprints of storm systems for the extended winter season ...
