Modulation of Stratosphere‐to‐Troposphere Transport of Ozone by North Pacific Weather Patterns
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Stratosphere‐to‐troposphere transport (STT) of ozone is a major natural source of tropospheric ozone and is tightly linked to both stratospheric and tropospheric circulations. However, the complex interactions of drivers make it challenging to understand the subseasonal variability of STT.

The Sudden Stratospheric Warming Events in the Antarctic in 2024
Geophysical Research LettersIn 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.

SuPerPoV: Score and Evolution of the Stratospheric Polar Vortex via Persistent Homology
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Classifying the stratospheric polar vortex provides predictability for surface weather on extended‐range timescales. However, all definitions of these events proposed in over 60 years of study depend on empirically chosen parameters and yield different results when they change.

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 ...

Bidirectional infrasonic ducts associated with sudden stratospheric warming events
, 2014 In January 2011, the state of the polar vortex in the midlatitudes changed significantly due to a minor sudden stratospheric warming event. As a result, a bidirectional duct for infrasound propagation developed in the middle atmosphere that persisted for

Analysis of gravity wave activity during stratospheric sudden warmings in the northern hemisphere
Earth and Planetary PhysicsDue 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
