On Tropical Cyclone Fullness

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract A series of recent papers in Geophysical Research Letters and the Journal of Geophysical Research Atmospheres have explored the usefulness of a new “fullness” metric characterizing the ratio of the inner and outer core size of tropical cyclones and suggesting that this metric is better correlated with tropical cyclone intensity, and even ...

Do Eclipse‐Induced Thermospheric TADs Originate From Above or Below?

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar eclipses generate significant wave activity in the Earth's upper atmosphere. The source region of eclipse‐induced Traveling Atmospheric Disturbances (TADs) in the upper thermosphere—particularly the relative contributions of gravity waves from the thermosphere itself versus the lower atmosphere—remains unknown. Using the Whole Atmosphere

DMS Uplift by Tropical Cyclones as a Source of SO2 in the Upper Troposphere

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Airborne observations from ACCLIP on 2 August 2022, combined with Lagrangian particle dispersion model back trajectories, reveal that SO2 mixing ratios at 14–16 km were enhanced by a factor of 4–6 in regions influenced by tropical cyclones (TCs).

Characterizing the Unique Chemical Imprint of On‐Axis, Lower‐Temperature Hydrothermal Flow to the Deep Ocean (Southern East Pacific Rise, 16.5°–18.0°S)

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract In addition to high‐temperature vents, lower‐temperature flow (LTF) (<300°C) is abundant along mid‐ocean ridges and contributes globally‐important fluxes of heat and water along with largely‐unconstrained geochemical influences on the ocean. We examined the impact of on‐axis LTF on the chemical composition of the overlying water column (<40 m ...
