On the Role of Dynamical Uncertainties in the Spread of Arctic Ozone Recovery Projections

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Arctic ozone is projected to recover over the 21st century in compliance with the Montreal Protocol. Chemistry‐climate models show a large spread in recovery rates and future changes in key dynamical features such as the polar vortex and the residual circulation.

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

International Journal of Climatology, Volume 46, Issue 6, May 2026.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical

Wasserstrudel zur Simulation der Planetenbildung: Ein Strudel als protoplanetare Scheibe

Physik in unserer Zeit, Volume 57, Issue 3, Page 124-129, May 2026.
Wie kann man die Dynamik einer protoplanetaren Scheibe studieren, die man sonst nur im All auf gigantischen Größenskalen beobachten kann? Wir stellen ein Laborexperiment als Analogie vor, das sehr einfach nachgebaut werden kann und eine erstaunliche gute Übereinstimmung liefert. Mit Hilfe einer Hochgeschwindigkeitskamera vergleichen wir den Strudel mit

Chemistry–climate feedback of atmospheric methane in a methane-emission-flux-driven chemistry–climate model [PDF]

Atmospheric Chemistry and Physics
The chemical sink of atmospheric methane (CH4) depends on the temperature and on the chemical composition. Here, we assess the feedback on atmospheric CH4 induced by changes in the chemical sink in a warming climate using a CH4-emission-flux-driven set ...

In-flight emission measurements with an autonomous payload behind a turboprop aircraft [PDF]

Atmospheric Measurement Techniques
This paper reports on the successful first deployment of a new, autonomously operating measurement system on a Grob G 520 Egrett aircraft, which was used as a chase aircraft to perform in-flight aerosol and trace gas measurements of engine exhaust from ...

Crowdsourcing the Frontier: Advancing Hybrid Physics‐ML Climate Simulation via a $50,000 Kaggle Competition

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Subgrid machine‐learning (machine learning [ML]) parameterizations have the potential to introduce a new generation of climate models that incorporate the effects of higher‐resolution physics without incurring the prohibitive computational cost associated with more explicit physics‐based simulations.

Contrail Formation Within Cirrus: Contrail Induced Perturbations and Cirrus Adjustments

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Contrail formation constitutes a large fraction of the aviation climate impact. But only part of the effect has been studied in detail, as research focused on contrail formation in cloud‐free air. Even though it is known that the impact of contrail formation within cirrus can be detected in space‐born remote sensing data, little research has ...

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.
