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 ...

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...

Mesoscale Soil Moisture Heterogeneity Can Locally Amplify Humid Heat

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Soil moisture is a key ingredient of humid heat through supplying moisture and modifying boundary layer properties. Soil moisture heterogeneity due to for example, antecedent rainfall, can strongly influence weather patterns; yet, its effect on humid heat is poorly understood.
