Influence of Variations in Gravity Wave Properties on Cirrus Ice Number Concentrations Produced by Homogeneous Freezing in the Tropical Tropopause Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract In this study, we examine the impact of variations in gravity wave properties on the ice crystal number concentrations in the tropical tropopause layer (TTL). Analysis of quasi‐Lagrangian superpressure balloon measurements from the Stratéole‐2 campaign shows that high‐frequency waves dominate the occurrence of relatively large vertical wind ...

Laboratory Experiments on Savannah and European Boreal Forest Fire Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Landscape fire is among the largest sources of aerosols and trace gases globally. However, the emissions are highly variable and strongly affected by the type of biomass and combustion characteristics. We investigated the effect of combustion characteristics on the burning emissions from three biomass types: woody plants and grasses from ...

An Evaluation of WRF‐Chem's Performance in Simulating PM2.5 in West African Cities

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract West Africa experiences some of the highest particulate pollution levels globally due to Saharan dust, biomass burning and urban emissions. Despite the severe health burden, air quality monitoring remains sparse. This study evaluates WRF‐Chem's performance in simulating PM2.5 levels across seven West African cities in 2021 using newly ...

Roles of Surface Latent Heat Flux and Gravity Waves in Offshore MCS Development in the Coastal Eastern Tropical Pacific

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The eastern tropical Pacific (ETP) coastal region, one of the rainiest places on Earth, is characterized by distinct diurnal offshore rainfall propagation primarily driven by mesoscale convective systems (MCSs). Previous studies have shown that MCS initiation in this region peaks in the early morning, with diurnally generated gravity waves ...
