Gas Measurements Reveal Fractional Degassing and Water Interaction During a Flank Eruption of Pacaya Volcano (Guatemala)

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract SO2 flux and gas composition were measured during the 2021 flank eruption of Pacaya Volcano (Guatemala). The SO2 flux, measured with Tropomi, gradually rose from ∼2 to ∼30 kg/s over a 5 month period before the eruption. Field UV camera data showed that >95% of the SO2 was emitted from the summit crater.

Comparison of Cold and Warm Extremes in the Mediterranean Based on E‐OBS and ERA5‐Land Data Sets

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Accurate characterization of temperature extremes is essential for climate risk assessment, particularly in regions highly sensitive to climate change like the Mediterranean Basin. This study compares near‐surface temperatures from E‐OBS and ERA5‐Land, focusing on warm (>90th percentile) and cold (<10th percentile) extremes.

Impact Craters Reveal a Deeper Rock‐Poor Regolith in the Lunar Highlands

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The only measurements of the highlands regolith occurred at the Apollo 14 and 16 landing sites, finding 10–15 m thick regolith; however, we show that the Apollo landing sites are anomalous due to their proximity to rare, highlands rocky craters and because they landed atop basin ejecta. Through observations of rocky crater populations, we show

Decadal Reversal of Eurasian Winter Temperature Trend Linked to North Atlantic Climate Variability

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The long‐term trend of Eurasian winter surface air temperature has undergone a distinct decadal change, shifting from a pronounced cooling trend between the late 1980s and late 2000s to a subsequent warming trend. This study demonstrates that this trend reversal is partly driven by decadal changes in North Atlantic sea surface temperature (SST)

The Maintenance of the Longitudinal Subtropical Jet Structure During Austral Winter

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The austral winter subtropical jet maintenance is analyzed by comparing the observed upper tropospheric zonal momentum budget with an idealized aquaplanet model simulation with localized tropical heating in the summer hemisphere. The model and observations show great similarity, demonstrating the dominant role of localized tropical convection ...

Stratospheric Quasi‐Biennial Oscillation Modulates Tropical Cyclone Extreme Rainfall Over East Asia via Intraseasonal Oscillation

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Tropical cyclone (TC)‐induced extreme precipitation (TCEP) poses heavy risks, yet its seasonal predictability remains limited by insufficient understanding of cross‐scale climatic drivers. Here, we elucidate a stratosphere‐to‐stratosphere coupling pathway where the quasi‐biennial oscillation (QBO) modulates TC activity and subsequent TCEP over

Escalating Uncertainty Under Increasing Risk in Compound Heat and Precipitation Extremes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Projection uncertainty fundamentally constrains climate adaptation, yet its evolution in compound heat and precipitation extremes (CHPE) remains poorly understood. Here we quantify CHPE uncertainty using 14 CMIP6 models and two single‐model initial‐condition large ensembles.

Spurious Drifts in the ITCZ Location and Associated Atmospheric Circulation in Decadal Climate Predictions

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Decadal predictions are affected by initialization shocks and drift, typically diagnosed in ocean circulation or temperature. It is not known, however, to what extent the drift can affect atmospheric dynamics. Here we investigate how the drift causes spatial shifts in the location of key large‐scale atmospheric circulation features such as the
