Model Sensitivities of Biomass‐Burning Aerosol Chemical Aging, Sulfate Formation, and Cloud Droplet Activation in the Southeastern Atlantic Using CESM and E3SM

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Biomass‐burning smoke drives large uncertainty in climate projections of the Earth's radiative balance. This is due to the chemical and physical evolution of smoke and its impact on clouds and radiation. Here we focus on the southeastern Atlantic region and its inflow of African biomass‐burning smoke during August 2017.

Impact of a Stratocumulus Scheme on Clouds and Feedbacks in MIROC7

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Marine stratocumulus (Sc) clouds exert a strong cooling effect on climate by reflecting solar radiation, yet many climate models underestimate their amount and cause uncertainty in equilibrium climate sensitivity (ECS). Herein, we show that incorporating a physically based Sc parameterization into the seventh version of the Model for ...

The Structure and Mesoscale Organization of Precipitating Stratocumulus

Journal of the Atmospheric Sciences, 2008
Abstract Large-eddy simulations are used to explore the structure and mesoscale organization of precipitating stratocumulus. The simulations incorporate a simple, two-moment, bulk representation of microphysical processes, which by varying specified droplet concentrations allows for comparisons of simulations that do and do not develop ...

High‐Resolution LiDAR Observations for Coupled Effects of Dry‐Air Entrainment and Haze‐Cloud Interactions on Cloud Vertical Structure

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract This study demonstrates the high‐resolution profiling of cloud microphysics in a laboratory chamber using Time‐Correlated Single Photon Counting (TCSPC) LiDAR. We present a novel retrieval method to derive vertical extinction (σ) $(\sigma )$ profiles, constrained by in situ measurements, to diagnose responses to dry‐air entrainment.

Evaluation of the ECHAM4 cloud-turbulence scheme for Stratocumulus

Meteorologische Zeitschrift, 2000
The behavior of the ECHAM4 cloud and turbulence scheme is evaluated for an idealized case of Stratocumulus. It is shown that the E-l turbulence closure that is used is sensitive to instabilities.

The Two‐Energies Turbulence Scheme Coupled to the Assumed PDF Method

Journal of Advances in Modeling Earth Systems, 2022
An update of the two‐energy turbulence scheme is presented, the 2TE + APDF scheme. The original version of the two‐energy scheme is able to successfully model shallow convection without the need of an additional parameterization for non‐local fluxes ...

Strong Diurnal‐Dependent Meteorological Control on Long‐Term Variations of Cloud Droplet Number Concentration

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract While long‐term cloud droplet number concentration (CDNC) changes are commonly attributed to aerosols, the role of meteorological factors remains poorly explored. Here, we perform a time‐resolved contribution analysis of long‐term CDNC variations using nearly two decades of geostationary observations over four Atlantic subtropical regions. The

CGILS Phase 2 LES intercomparison of response of subtropical marine low cloud regimes to CO2 quadrupling and a CMIP3 composite forcing change

Journal of Advances in Modeling Earth Systems, 2016
Phase 1 of the CGILS large‐eddy simulation (LES) intercomparison is extended to understand if subtropical marine boundary‐layer clouds respond to idealized climate perturbations consistently in six LES models.

Assessing Cloud and Precipitation Properties on Temporal Scales Using LASSO Simulations Over the ARM Eastern North Atlantic (ENA) Site

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract The representation of low clouds and precipitation remains a major source of uncertainty in Earth System Models (ESMs), particularly due to challenges in representing their sub‐grid variability and scale‐dependent sampling. This study evaluates the performance of preliminary simulations from the Large‐Eddy Simulation (LES) Atmospheric ...
