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

Substantial Diel Changes of Cloud Adjustments to Aerosols in Ship‐Tracks

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Clouds adjust their albedo, amount and liquid water path to anthropogenic aerosols, and produce a climate forcing. Such cloud adjustments are complex functions of both environmental conditions and interaction time. However, direct observations of temporal changes in cloud adjustments are limited. Here, we develop a method to show observational

Radiocarbon Evidence for the Springtime Injection of South Himalayas Biomass Burning Into the Urban Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Carbonaceous aerosols (CA) on the Tibetan Plateau (TP) accelerate glacial melt, yet decoupling local emissions from transboundary transport remains challenging. We conducted a year‐long radiocarbon (14C) study in Lhasa, identifying it as a CA hotspot. Fossil fuels dominated EC (69%), while non‐fossil sources contributed 54% to OC.

Formation of Shallow Cumulus Patterns Using a Simple Warm Cloud Precipitation Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract A simple model based on predator‐prey‐like dynamics using a system of four nonlinear ordinary differential equations is used to simulate the life cycle of shallow cumulus. By coupling this model across a two‐dimensional array and varying the cloud environment, we can simulate three common patterns of self‐aggregation seen in the maritime ...

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
