The Influence of Aged Smoke on Urban Ozone: Aircraft Measurements in Chicago During the 2023 Canadian Wildfires

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract As large wildfires become more frequent and severe in North America due to heightened fuel aridity and fire weather conditions driven by anthropogenic climate change, wildfire smoke has an increasingly important influence on air quality. Transported smoke can impact urban boundary layer ozone (O3) directly, via the entrainment of O3 formed in ...

Sudden Variation Effect of Aerodynamic Loads and Safety Analysis of Running Trains When Entering Tunnel Under Crosswind

Applied Sciences, 2020
Sudden variation of aerodynamic loads is a potential source of safety accidents of high-speed trains (HSTs). As a follow-up investigation on the aerodynamic response of a HST that enters a tunnel under crosswind environment, this paper focuses on the ...

Disrupted Skies: How Offshore Wind Farms Alter Flight Behavior of Breeding Seabirds

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Using high‐resolution 1‐s tracking bursts collected every hour, we quantified within‐trajectory flight behavior of breeding Bridled Terns near offshore wind farms. Birds showed increased mean redirection and lower flight altitude when trajectories were more closely aligned with turbine directions from the colony, suggesting localized, direction ...

Neutral Wind Dynamics in High‐Latitude Regions During the 17 March 2013 Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Neutral winds play a critical role in transporting mass, momentum, and energy throughout the upper atmosphere. During geomagnetic storms, momentum is transferred to the thermosphere primarily through ion–neutral collisions, along with other forces. This study investigates high‐latitude neutral wind dynamics during the 17 March 2013 storm using

Migrating and Nonmigrating Neutral Mass Density Tides From GRACE‐FO Observations for Solar Minimum Conditions

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study presents the migrating and nonmigrating thermospheric neutral mass density tides from the Gravity Recovery And Climate Experiment Follow‐On (GRACE‐FO) observations under solar minimum conditions (year 2020). The observed densities are first mapped to a reference altitude of 500 km using an empirical model (NRLMSIS 2.0) to remove the

Field test of assumptions for using line transect distance sampling on rock ptarmigan

Wildlife Biology, Volume 2026, Issue 4, July 2026.
Reliable population estimates are essential for the management of harvested species. Line transect distance sampling using pointing dogs is an established survey method for willow ptarmigan and has also been proposed for the monitoring of rock ptarmigan.

Soil Moisture Impact on Convective Initiation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

Optimized Design and Numerical Analysis of Dust Removal in Blast Furnace Nozzle Based on Air Volume-Structure Coordinated Control

Atmosphere
Blast furnace tuyeres are the primary dust emission source in ironmaking facilities (accounting for over 30% of total pollutants). High-temperature dust plumes with intense thermal energy are prone to dispersion, while China’s steel industry ultra-low ...
