The Ionospheric Lunar Tidal Response to the 2020–2021 Sudden Stratospheric Warming Observed by COSMIC‐2, ICON and Modeled by SD‐WACCMX, TIE‐GCM

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract This study examines how the breakdown of the stratospheric polar vortex influences lunar semidiurnal (M2) tides in F‐region electron density using Global Ionospheric Specification (GIS) data from the Constellation Observing System for Meteorology, Ionosphere, and Climate‐2 (COSMIC‐2).

Constraining the Stratospheric Sulfate Budget in Global Models: Insights From In Situ OCS Measurements During 2023 SABRE and Comparison With Satellite, Balloon and Surface Data

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract In situ carbonyl sulfide (OCS) measurements from the Stratospheric Aerosol processes, Budget and Radiative Effects (SABRE) 2023 airborne campaign are used to evaluate the sulfate budget in the Arctic stratosphere during boreal winter. The strong correspondence between these measurements and remote retrievals from the Atmospheric Chemistry ...

Opposite spectral properties of Rossby waves during weak and strong stratospheric polar vortex events [PDF]

Weather and Climate Dynamics
In this study we provide a systematic characterization of Rossby wave activity during the 25 sudden stratospheric warming (SSW) and 31 strong polar vortex (SPV) events that occurred in the period 1979–2021, identifying the specific tropospheric and ...

Descent from the polar mesosphere and anomalously high stratopause observed in 8 years of water vapor and temperature satellite observations by the Odin Sub-Millimeter Radiometer [PDF]

, 2010
Using newly analyzed mesospheric water vapor and temperature observations from the Sub-Millimeter Radiometer instrument aboard the Odin research satellite over the period 2001-2009, we present evidence for an anomalously strong descent of dry mesospheric

The Effect of Zonally Asymmetric Ozone Heating on the Northern Hemisphere Winter Polar Stratosphere [PDF]

, 2011
[1] Previous modeling studies have found significant differences in winter extratropical stratospheric temperatures depending on the presence or absence of zonally asymmetric ozone heating (ZAOH), yet the physical mechanism causing these differences has ...

Comparison of Antarctic total ozone behavior in pre-SSW, SSW, and post-SSW years

Український антарктичний журнал
Sudden stratospheric warmings (SSWs) are dramatic events characterized by sudden and sharp changes in the distribution of polar stratospheric temperatures, zonal winds, total ozone column, and other atmospheric parameters.
