Spatial heterogeneity of cloud hydrometeors during extreme monsoon rainfall over India

Environmental Research Communications
Cloud feedback mechanisms remain a major source of uncertainty in weather prediction, particularly over monsoon dominated regions like India where rainfall exhibits strong spatial and temporal variability.

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Satellite‐Based Diagnostics of Precipitation Process in Mixed‐Phase Clouds: Extension From Warm Rain Process Statistics

Geophysical Research Letters
This study proposes a methodology for analyzing the precipitation process in mixed‐phase clouds using multisensor satellite data, including radar, lidar, and imager. By leveraging a specific multivariate statistic, we elucidate the vertical microphysical

No Guide to Ground: Right‐Making and Right‐Makers

Noûs, Volume 60, Issue 3, Page 606-618, September 2026.
ABSTRACT It is often taken for granted that right‐makers, that is, the things that make something—say, an action—right, do so by explaining why it is right. This view can be spelled out in terms of metaphysical ground: right‐making just is grounding of rightness facts.

Unstructured Purity

Noûs, Volume 60, Issue 3, Page 685-697, September 2026.
ABSTRACT Purity is the principle that fundamental facts only have fundamental constituents. In recent years, it has played a significant (if sometimes implicit) role in metaphysical theorizing. A philosopher will argue that a fact [p]$[p]$ contains a derivative entity and cite Purity as a reason to deny that [p]$[p]$ is fundamental. I argue that recent

Significance of Size‐Dependent Hygroscopicity Parameterization for Aerosol‐Cloud Interactions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Aerosol‐cloud interactions (aerosol indirect effects) are the most significant source of uncertainties in the effective radiative forcing (ERF) due to aerosols which can act as cloud condensation nuclei (CCN). Uncertainties in the indirect effect can result from systematic uncertainties in aerosol water uptake (hygroscopicity).

Development and Evaluation of an Urban Atmospheric Inverse Modeling Framework for the Washington, DC and Baltimore, MD Metropolitan Area: Initial Results From an Inert Tracer Case Study

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Accurate quantification of hazardous material releases in cities is critical for emergency managers aiming to mitigate health impacts and mortality in the population. Here, a study on the development and evaluation of a high‐resolution (1‐km, 1‐hr) urban‐scale atmospheric inverse modeling system for the Washington, DC, and Baltimore, MD ...

Microphysical Simulation of the 2022 Hunga Volcano Eruption Using a Sectional Aerosol Model

Geophysical Research Letters
Approximately 150 Tg of water vapor and 0.42 Tg of sulfur dioxide were injected directly into the stratosphere by the January 2022 Hunga volcanic eruption, which represents the largest water vapor injection in the satellite era. A comparison of numerical

Unveiling the Shortwave Absorption Spectra of Alumina Aerosols: Radiative Implications for Solar Radiation Modification

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Alumina is proposed for Stratospheric Aerosol Injection (SAI)‐based solar radiation modification due to its presumed ability to scatter sunlight strongly while absorbing weakly. Alumina is assigned negligible solar shortwave absorption in climate models; this assumption is not validated owing to technological challenges in quantifying its weak

Sea Surface Temperature Feedbacks and Convective Organization Mediate the Tropical Circulation Response to Aerosols

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Coupling between aerosols, atmospheric circulation, and tropical sea surface temperature (SST) patterns is an important part of anthropogenic influence on climate but is not well understood. Using idealized, cloud‐resolving simulations with a slab ocean, we examine the hydrologic and circulation responses to uniform and spatially varying ...
