Evolution of the water cluster in pore condensation

Droplet, Volume 5, Issue 2, April 2026.
In pore condensation, lower contact angles reduce molecular displacement (60%) and potential energy (10%), enhancing vapor capture tenfold. Pores restrict water molecule mobility, promoting condensation. On hydrophobic surfaces (124∘$^\circ$), pores stabilize embryos, ensuring uniform condensation within pores, boosting nucleation efficiency.

Numerical simulations of contrail-to-cirrus transition – Part 2: Impact of initial ice crystal number, radiation, stratification, secondary nucleation and layer depth [PDF]

Atmospheric Chemistry and Physics, 2010
Simulations of contrail-to-cirrus transition were performed with an LES model. In Part 1 the impact of relative humidity, temperature and vertical wind shear was explored in a detailed parametric study.

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Influence of temperature and humidity on contrail formation regions in the general circulation model EMAC: a spring case study [PDF]

Atmospheric Chemistry and Physics
While carbon dioxide emissions from aviation often dominate climate change discussions, non-CO2 effects such as contrails and contrail cirrus must also be considered.

Modeling the Impact of Alternative Fuels and Hydrogen Propulsion on Contrail‐Cirrus: A Parameter Study

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Line‐shaped contrails formed behind aircraft can evolve into broadly spread and long‐living cirrus clouds under favorable conditions. These contrail‐cirrus contribute significantly to the aviation‐induced radiative forcing. While past modeling studies have examined contrail‐cirrus across various atmospheric and aircraft‐type dependent ...

Formation of Hole Punch Clouds

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Hole‐punch clouds (HPCs) are circular or oval cloudless holes in thin supercooled cloud layers. They are believed to be generated by aircraft passing through supercooled cloud layers; however, the exact formation mechanisms remain poorly understood due to the scarcity of observations.

Freshly Generated Super Sunrise Plasma Bubbles During the Geomagnetic Storm on November 5–6, 2023

Space Weather, Volume 24, Issue 1, January 2026.
Abstract During the geomagnetic storm on November 5–6, 2023, freshly generated super sunrise equatorial plasma bubbles (EPBs) and associated irregularities over the 80°–140°E sector were observed combining ground‐based and space observations from GNSS, ionosondes, HF Doppler records, and several satellite missions (COSMIC2, Swarm, and DMSP).

An adaptive segmentation approach for contrail detection in meteosat second generation satellite imagery [PDF]

Atmospheric Measurement Techniques
Line-shaped ice clouds known as contrails are produced by aircraft and play a notable role in aviation’s contribution to climate change. One promising and cost-effective approach to mitigating this impact is the operational avoidance of contrail ...
