Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface. Whether the resulting poroelastic stress changes promote seismicity and larger megathrust events, however, remains unclear.

Air Quality Penalty in Southeast Asia Driven by AMOC Slowdown

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) regulates Earth's climate by redistributing heat and freshwater across the Atlantic Ocean. While accelerating Arctic melt is expected to weaken the AMOC, its implications for atmospheric composition remain poorly understood.

Observed and Modeled Changes in Boundary‐Layer and Surface‐Level Actinic Flux Due To Wildfire Smoke Plumes in the California Central Valley in Summer 2018

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfire smoke is increasingly degrading U.S. air quality via the emission and transport of pollutants. Smoke's direct role as a pollutant is well‐documented; however, smoke also affects pollutant concentration indirectly by changing the shortwave actinic flux necessary for photochemical reactions.

Weather Regime Diversity, Transitions, and Trends Using Hexagonal Self‐Organizing Maps

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Persistent atmospheric circulation patterns, or weather regimes, strongly modulate surface weather and extremes, yet their internal diversity, transitions, and trends remain less understood for North America. We apply a self‐organizing map (SOM) framework to represent North American weather regimes using daily 500‐hPa geopotential height ...

Geostationary Air Quality Monitoring Substantiates Column NO2 as a Better O3 Formation Regime Indicator in China

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract China has become a global hotspot of ozone (O3) pollution, and understanding O3 formation regime is crucial for air quality management. Satellite‐observed formaldehyde‐to‐nitrogen‐dioxide ratio (HCHO/NO2, FNR) has long been demonstrated as an efficient way to infer O3 formation regime.
