Surface Air Enrichment of Cosmogenic 35S at a Subtropical Site During the May 2024 Solar Superstorm

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Cosmogenic radiosulfur (35S) is produced in the atmosphere by high‐energy particle interactions and serves as a sensitive tracer of stratospheric intrusions. In May 2024, an extreme solar storm provided a rare opportunity to examine atmospheric 35S responses to intense solar activity.

Elliptical Orbit Representation for the Annual Evolution of the Northern Hemisphere Stratospheric Polar Vortex. Part I: Diagnosing Interannual Variability

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Using a single annual frequency with each year defined from July 1 to June 30 of the following calendar year, this study fits an ellipse to the yearly phase space trajectory of the daily time series of MU (stratospheric mass‐weighted zonally integrated zonal wind at 60°N) and M (total polar stratospheric air mass over 60–90°N) to represent the

Elliptical Orbit Representation for the Annual Evolution of the Northern Hemisphere Stratospheric Polar Vortex. Part II: Long‐Lead Forecasts of Wintertime S2S Anomalies

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In Part I, we represent the annual evolution of the Northern Hemisphere stratospheric polar vortex (SPV) in individual years using an ellipse, defined through six ellipse parameters, for the phase‐space trajectory of the daily time series of MU (mass‐weighted zonally integrated zonal wind at 60°N above 400 K) and M (stratospheric air mass over

Rainfall and Rain‐on‐Snow Events Over Greenland in Summer: Climatology, Trends, Synoptics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Rain‐on‐snow (ROS) events in the Arctic can lead to major impacts on the snow cover, cryosphere and environment. During the last decades, these events have significantly increased, mostly due to climate change. Here, we use outputs from the regional climate model MAR (version 3.14) driven by the ERA5 reanalysis at 10‐km resolution over ...

Attribution of Interdecadal Changes in the Spatial Structure of the Spring AO

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The Arctic Oscillation (AO) is one of the key atmospheric circulation modes in the mid‐to‐high latitudes of the Northern Hemisphere. The spatial structure of the spring AO exhibits pronounced interdecadal variation, primarily characterized by a shift of the midlatitude circulation center from the North Pacific Center (NPC) to the North ...

EP‐ENSO Transition Facilitated the Kuroshio‐Oyashio Extension SST Anomalies to Reverse in Early and Late Autumn

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Kuroshio‐Oyashio extension sea surface temperature (SSTKOE) anomalies modulate local marine ecosystems and nearby climate extremes. Recent studies have preliminarily revealed that the SSTKOE anomalies reverse in early and late autumn, but its precursor drivers are still unclear.

An actionable framework for AI‐ready data

AI Magazine, Volume 47, Issue 1, Spring 2026.
Abstract Data is the foundation of AI. Poor‐quality data drive up costs and can lead to hidden problems for AI models, especially in complex fields such as healthcare and manufacturing. Meanwhile, biased data negatively affect the performance of AI models, and untested evaluation datasets can result in false positives or overestimates of model accuracy.

Weakening of Western Disturbances in Response to Polar Sea Ice Melt in Climate Model Simulations

Atmospheric Science Letters, Volume 27, Issue 3, March 2026.
We investigate how polar sea ice loss influences western disturbances over South Asia using climate model experiments. The simulations reveal a robust weakening of western disturbance activity in response to Polar Sea ice melt. These results highlight a critical teleconnection pathway through which high‐latitude cryospheric changes may impact South ...

Investigating the Role of Climate Change in the 3 May 2025 Western Europe Hailstorm Using Atmospheric Analogs

Atmospheric Science Letters, Volume 27, Issue 3, March 2026.
We analyzed the 3 May 2025 Paris hailstorm to assess climate change's influence using ERA5 data and analogue‐based attribution. Comparing present and past atmospheric patterns, we found that today's warmer climate shows stronger instability and energy, favoring large hail formation.
