Process‐Oriented Calibration of a Turbulence Scheme in the DOE's Global Storm‐Resolving Model Using Machine Learning

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract A process‐oriented calibration framework is developed for the Simplified Higher‐Order Closure (SHOC) turbulence scheme in DOE's Simple Cloud Resolving E3SM Atmospheric Model (SCREAM). This framework leverages machine learning surrogates and observational constraints to efficiently calibrate SHOC adjustable parameters across two convective ...

Transport to the Extratropical Stratosphere by Overshooting Storms in Idealized Simulations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Deep convection is a significant source of water to the extratropical stratosphere which can alter radiative properties and contribute to ozone loss. Previous studies find it responsible for 40% of mid‐latitude water vapor above 380K. However, the amount of hydration from individual storms and the mechanisms that initiate mixing is less ...

Wave‐Based Quantification of Ion Composition in the Earth's Magnetosphere‐Ionosphere‐Coupling Region

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Ion composition critically determines the basic kinetic characteristics of plasma and affects energy transmission of the magnetosphere. However, it exhibits significant variations with altitude, latitude, local time, longitude, and also with geomagnetic and solar activity.

Mass Addition to Timpanogos Rock Glacier: Debris‐Covered Snow and the Importance of Interannual Variability in Headwall Erosion and Climate

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The processes of ice incorporation into rock glaciers have been difficult to quantify in both permafrost and non‐permafrost conditions. Here, we develop a numerical model that regardless of the presence of permafrost, reveals how debris eroded from hillslopes and deposited on snow can add ice mass to rock glaciers in pulses.

Could Narrow Bipolar Events Serve as a Distinct Lightning Proxy for Revealing Overshooting Thunderclouds Development?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Narrow bipolar events (NBEs) are often generated in overshooting thunderclouds (OT) penetrating the stratosphere. However, how and under what conditions OT produces such discharges remains unclear. With 3‐year lightning observations and simultaneous cloud top brightness temperature measurements over South China, we developed a more accurate OT
