Windblown Diatoms for Reconstructing Westerly Wind Variability in the South Atlantic Sector of the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Southern Hemisphere westerly winds are important drivers of Antarctic and sub‐Antarctic environmental change. Short observational wind records prevent us from fully understanding the scope of their variability. Proxy records provide valuable tools to extend environmental records. Here we present a novel wind study based on the use of windblown

Land‐Feedbacks‐Driven Dry‐Hot Mutual Reinforcement Extends Global Compound Drought‐Heatwave Durations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Under global warming, numerous compound events have emerged, yet the physical linkages between the two factors often remain unclear. The increasing frequency of droughts and heatwaves has raised the likelihood of compound drought and heatwave events (CDHE) worldwide, accompanied by frequent long‐lasting mega‐CDHE posing serious exposure risks.

Large Eddy Simulations of the Atmospheric Boundary Layer Over Satellite‐Sensed Sea Ice Maps

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Surface heterogeneity in the marginal ice zone (MIZ) causes multiscale secondary atmospheric circulations that are challenging to model or observe. The absence or inadequate representation of these circulations in ocean‐atmosphere exchange schemes in climate models is partially responsible for the underestimation of Arctic sea ice loss ...

Mechanisms for Meridional Propagation of Global Mesoscale Ocean Eddies Within a PV‐Based Dynamic Framework

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Mesoscale eddies are crucial for global heat and tracer transport, yet the mechanisms underlying their meridional movement remain unclear. Here, we combine satellite observations, idealized numerical experiments, and theoretical modeling to investigate these mechanisms. We demonstrate that the meridional eddy movement is strongly linked to the

Global Glacial Rock Weathering Signature Depends on Competing Contributions From Ice Sheets and Alpine Glaciers

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Rock weathering influences Earth's atmosphere and climate. The dissolution of silicate minerals draws down atmospheric CO2 while sulfide oxidation coupled with carbonate dissolution releases CO2. Alpine glacier rock weathering causes high sulfide oxidation and carbonate dissolution.
