Large‐eddy simulation of subtropical cloud‐topped boundary layers: 1. A forcing framework with closed surface energy balance

Journal of Advances in Modeling Earth Systems, 2016
Large‐eddy simulation (LES) of clouds has the potential to resolve a central question in climate dynamics, namely, how subtropical marine boundary layer (MBL) clouds respond to global warming.

Attributing Long‐Term Trends in Marine Low Cloud Morphologies to Aerosols and Large‐Scale Meteorology With Deep Learning

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The response of marine low‐cloud mesoscale morphologies to climate change and emission reductions remains poorly understood. Here, we link long‐term trends in six cloud morphologies to variations in large‐scale meteorology and aerosols. The trends show strong spatial heterogeneity, with closed and disorganized mesoscale cellular convection ...

Pivotal Role of Cloud‐Planetary Boundary Layer Coupling to Explain Contrasting Aerosol‐Cloud Relationships

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The radiative effect of aerosol on cloud albedo via altering cloud droplet effective radius (re) is a major uncertainty in the Earth's climate system. Remote sensing studies have reported either negative or positive relationships between re and aerosol number concentration (Na) or other aerosol proxies.

On the relationship between responses in cloud water and precipitation to changes in aerosol [PDF]

Atmospheric Chemistry and Physics, 2014
Climate models continue to exhibit strong sensitivity to the representation of aerosol effects on cloud reflectance and cloud amount. This paper evaluates a proposed method to constrain modeled cloud liquid water path (LWP) adjustments in response to ...

Low Cloud Dispersion Effects by Anthropogenic Aerosols in Polluted Air

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Aerosol–cloud interactions (ACI) are a major source of uncertainty in anthropogenic climate forcing. Anthropogenic aerosols modulate the cloud albedo by impacting the relative dispersion (ε) of cloud droplet size distributions (CDSDs), known as the dispersion effect.

Kernel‐Based Estimation of Stratospheric Aerosol Radiative Effects From Volcanic and Wildfire Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract To facilitate the quantification of the stratospheric aerosol direct radiative effect (ARE), this study develops a suite of aerosol kernels based on Modern‐Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data. The kernels comprise a five‐dimensional data set that includes latitude, longitude, time, wavelength ...

Resolving Droplet Sedimentation Effects in Stratocumulus Clouds

Journal of Advances in Modeling Earth Systems
AbstractWe use direct numerical simulations to quantify the effects that droplet sedimentation has on the stratocumulus‐topped boundary layer. Our analysis includes both ends of the length‐scale spectrum that are deemed important for representing turbulence in stratocumulus clouds, spanning from meter scales at the cloud top to large energy‐containing ...

Biases in Southern Ocean Precipitation From Shallow Convection: The Role of Cloud Morphology

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Precipitation from marine boundary layer clouds is a critical yet highly uncertain feature of post‐frontal conditions over the Southern Ocean (SO), where shallow convection dominates. This study evaluates whether satellite retrievals (GPM‐IMERG and CloudSat) and reanalysis (ERA5) represent the contrasting precipitation between open and closed ...

Exposing and Reducing Biases of Simulating Mixed‐Phase Clouds in the Convection‐Permitting E3SM Atmosphere Model: Lessons From an Arctic Cold‐Air Outbreak

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Mixed‐phase clouds modulate the water and energy cycles of high‐latitude regions, yet their liquid‐ice phase partitioning has long been poorly simulated in climate models. Here, simulations of Arctic mixed‐phase clouds by the Simple Cloud‐Resolving E3SM Atmosphere Model (SCREAM) are assessed against large‐eddy simulations, satellite data, and ...
