Volcanic Eruptions Reorganize Climate Teleconnections: Detection via Riemannian Covariance Fingerprinting

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

Structure, Propagation and Variability of the 5‐Day Rossby‐Haurwitz Wave

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract The 5‐day wave is the gravest free Rossby mode predicted by the Laplace shallow water equations, with a latitudinally symmetric, zonal wavenumber one theoretical structure in geopotential extending from pole to pole. It propagates westward along the equator at about 98 m s−1 ${\mathrm{s}}^{-1}$ and was first observed in surface pressure data ...

The Predictability of the Downward Versus Non‐Downward Propagation of Sudden Stratospheric Warmings in S2S Hindcasts

Geophysical Research Letters
Roughly one‐third of sudden stratospheric warming (SSW) events lack a strong canonical surface response, and this can lead to a forecast bust if a strong response was predicted.

Agricultural Emissions of Reactive Nitrogen Gases From Constrained Simulations Using the Community Land Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Reactive nitrogen (Nr) gases (NH3, N2O, and NO) emitted from agricultural fields constitute a substantial portion of the Nr flux from land to the atmosphere. Here, we coupled the Flows of Agricultural Nitrogen (FANv3) with a modified version of the Community Land Model (CLM5.1) to produce a model (CLM‐FANv3) that simulates the emissions of NH3,

Overview of Aerosols in the E3SM Version 3: New Model Features and Their Impacts

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Accurate and comprehensive representation of aerosols in Earth system models (ESMs) is critical for modeling radiative forcing and seasonal‐to‐decadal variability. With increasing computing power, detailed physical and chemical processes representing aerosols and their interactions with other components of the Earth system can be treated more ...

Latitudinal Dependence of the Geomagnetic and Solar Activity Effect on Sporadic‐E Layer

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Based on the global COSMIC occultation data, the latitudinal dependence of the geomagnetic and solar activity effect on the sporadic‐E (Es) layer is statically investigated. At middle geomagnetic latitudes, Es occurrence rates generally decrease with increasing solar activity, except during winter and spring in the Southern Hemisphere.

A dataset of Beijing MST radar horizontal wind fields at Xianghe Station in 2012

中国科学数据
The atmospheric horizontal wind is an essential parameter for studying atmospheric dynamic characteristics, processes, and dynamic coupling between the upper and lower atmosphere. MST (Mesosphere Stratosphere and Troposphere) radar plays a unique role in

Prescribing Zonally Asymmetric Ozone Climatologies in Climate Models: Performance Compared to a Chemistry‐Climate Model

Journal of Advances in Modeling Earth Systems, 2019
Three different methods of specifying ozone in an atmosphere‐only version of the HadGEM3‐A global circulation model are compared to the coupled chemistry configuration of this model.

Tertiary‐Ozone‐Maximum‐Like Mesospheric Ozone Increases Driven by Solar Eclipses: Sensitivity Experiments on WACCM‐X

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar eclipses offer natural experiments to isolate the photochemical response of mesospheric ozone to solar radiation. Using the WACCM‐X model, we performed mechanism‐oriented sensitivity experiments for the 14 December 2020 eclipse to quantify the tertiary‐ozone‐maximum‐like (TOM‐like) response.

Replacing Tunable Parameters in Weather and Climate Models With State‐Dependent Functions Using Reinforcement Learning

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Weather and climate models rely on parameterizations to represent unresolved sub‐grid processes. Traditional schemes rely on fixed coefficients that are weakly constrained and tuned offline, contributing to persistent biases that limit their ability to adapt to underlying physics.
