Effects of a Vertical Cloud Condensation Nuclei Concentration Explosion in an Idealized Hailstorm Simulation

Geophysical Research Letters
Determination of the key vertical level for cloud condensation nuclei concentration (CCNC) explosions has been a long‐term issue in CCN‐cloud interaction studies.

A Deep‐Learning‐Based Wind Gust Estimation Scheme in Complex Terrain

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Accurate prediction of gusts is critical for risk mitigation, but the turbulent processes that generate gusts are unresolved in conventional numerical weather prediction models. Here we introduce a deep‐learning‐based wind gust estimation scheme (DL‐GUST) that uses archived diagnostics from the Weather Research and Forecasting (WRF) model ...

Morphological and Size‐Dependent Enrichment of Endotoxins in Coastal Spray Aerosols: Implications for Regional Respiratory Health Risks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Sea spray aerosols (SSA) transport bioactive substances that affect the Earth's environmental and climate system. We investigated the enrichment of endotoxins (LPS), characterized their influence on the SSA morphologies, and evaluated the respiratory tract deposition.

Microphysical Characteristics of a Squall Line Modulated by the Northeast China Cold Vortex Using Polarimetric Radar and Disdrometer Observations

Remote Sensing
Heavy precipitation in Northeast China is frequently modulated by the Northeast China Cold Vortex (NCCV), although the microphysical processes within squall lines under such conditions remain insufficiently understood. This study presents a comprehensive

Lidar Ratios and Fluorescence Properties of Stratospheric Volcanic Sulfate

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract From January to June 2025, a stratospheric sulfate layer originating from the eruptions of the Ruang volcano in April 2024 could be observed with a multi‐wavelength Raman and fluorescence lidar over Leipzig, Germany. The aerosol‐optical depth of the stratospheric volcanic sulfate was <0.02 ${< } 0.02$, decreasing with time.

On WRF hybrid-dynamic regression approach in heavy rainfall forecasting over the Northern of Thailand

Frontiers in Environmental Science
Rainfall forecasting in Northern Thailand presents considerable challenges due to the complex topography of the region and its highly variable climatic conditions, particularly during periods of heavy rainfall in August. This is compounded by limitations

Unifying Observations, Simulations, and Theory for Drizzle Size Distribution Tails

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The onset and rate of drizzle remain open problems in atmospheric physics. This study brings together theory, simulations, and observations to analyze the emergence of power‐law tails in droplet size distributions as a signature of a dynamic steady state with coalescence growth balanced by sedimentation removal.

The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

The Microphysics of Deportation

, 2019
In the paper, I argue there is a whole political logistics to deportation. This is made visible by bringing the concept of microphysics to bear on the topic. Taking the case of enforced and escorted removals from the UK, I show that this logistics is vividly and graphically documented in the inspection reports.

Regional and Seasonal Variability in Decreasing Contrail Cirrus Cloudiness Using Sustainable Aviation Fuel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract The impact of aviation induced contrail cirrus on Earth's radiation budget depends on the optical depth (OD) and the life time of these clouds. Their tendency to enhance global warming may be mitigated by replacing conventional kerosene with fuels that form fewer soot particles, such as sustainable aviation fuels (SAF). The resulting reduction
