Land Cover Change Drives River Flow Modifications in Central Chile

Hydrological Processes, Volume 40, Issue 5, May 2026.
This study examines the combined effects of land cover change and ENSO on streamflow dynamics in four coastal catchments of central Chile, using a 45‐year (1979–2023) dataset of remote sensing and hydroclimatic data. Conclusions Native forest loss reduced summer flows and PP–Q relationship; preserved forests enhanced resilience.

Separating Source and Precipitation Effects on Cloud and Rain Pollution Concentrations on Mount Washington, NH

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Precipitation processes are critical for removing pollutants from the atmosphere, yet in many mid‐latitude continental regions, the effects of rainout are difficult to distinguish from the broader influence of atmospheric transport. In this study, we analyze 582 cloud and rain samples collected during summers 1996–2014 from Mount Washington ...

Background Atmospheric CO2 Regulates the Local and Non‐Local Climate Impacts of Amazon Deforestation

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Amazon deforestation has substantial impacts on the local and regional climate system, yet the extent to which future atmospheric CO2 trajectories modulate these impacts remains unclear. Here, we assess the climatic impacts of Amazon deforestation under contrasting atmospheric CO2 scenarios using the Community Earth System Model version 2 ...

Beyond the Training Data: Confidence‐Guided Mixing of Parameterizations in a Hybrid AI‐Climate Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Persistent systematic errors in Earth system models (ESMs) arise from difficulties in representing the full diversity of subgrid, multiscale atmospheric convection and turbulence. Machine learning (ML) parameterizations trained on short high‐resolution simulations show strong potential to reduce these errors.

Roles of Surface Latent Heat Flux and Gravity Waves in Offshore MCS Development in the Coastal Eastern Tropical Pacific

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The eastern tropical Pacific (ETP) coastal region, one of the rainiest places on Earth, is characterized by distinct diurnal offshore rainfall propagation primarily driven by mesoscale convective systems (MCSs). Previous studies have shown that MCS initiation in this region peaks in the early morning, with diurnally generated gravity waves ...

Imputing Missing Long‐Term Spatiotemporal Multivariate Atmospheric Data With CNN‐Transformer Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Continuous physical domains are important for scientific investigations of dynamical processes in the atmosphere. However, missing data—arising from operational constraints and adverse environmental conditions—pose significant challenges to accurate analysis and modeling.

Seismic Stratigraphy of the Peruvian Forearc Drifts from 3° to 7°S: Identification and Influence of Lower Layers of the Humboldt Current System

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The seafloor morphology and subsurface geometry of a late Neogene contourite drift located along the Peru margin is documented for the first time using multibeam bathymetry, two‐dimensional and three‐dimensional seismic data. Along the margin several submarine canyons incise the shelf and slope.
