Detection and characterization of heavy drizzle cells within subtropical marine stratocumulus using AMSR-E 89-GHz passive microwave measurements [PDF]

Atmospheric Measurement Techniques, 2013
This empirical study demonstrates the feasibility of using 89-GHz Advanced Microwave Scanning Radiometer–Earth Observing System (AMSR-E) passive microwave brightness temperature data to detect heavily drizzling cells within subtropical marine ...

Characteristics of a Multi‐Model Ensemble of Mock‐Walker Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract The Radiative‐Convective Equilibrium Model Intercomparison Project (RCEMIP) phase I provided insights into the tropical radiative‐convective equilibrium state across an unprecedented ensemble of models that includes both those with parameterized and explicit convection.

Simulation of marine stratocumulus using the super-droplet method: numerical convergence and comparison to a double-moment bulk scheme using SCALE-SDM 5.2.6-2.3.1 [PDF]

Geoscientific Model Development
The super-droplet method (SDM) is a Lagrangian particle-based numerical scheme for cloud microphysics. In this work, a series of simulations based on the DYCOMS-II (RF02) setup with different horizontal and vertical resolutions are conducted to explore ...

The effects of turbulent collision–coalescence on precipitation formation and precipitation-dynamical feedbacks in simulations of stratocumulus and shallow cumulus convection [PDF]

Atmospheric Chemistry and Physics, 2014
A double moment warm rain scheme that includes the effects of turbulence on droplet collision rates has been implemented in a large-eddy model to investigate the impact of turbulence effects on clouds and precipitation. Simulations of shallow cumulus and

Invisible Ship Tracks Produce Mean‐State Cloud Microphysics Perturbation in Tropical Trade Cumulus

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Aerosol effects in cumulus‐topped boundary layers remain relatively unconstrained and drive uncertainty in climate modeling. We assess the impacts of shipping aerosol on trade cumulus, combining satellite retrievals and large eddy simulations (LES).

Postfrontal Deep Convection Over the Southern Ocean and Orographic Precipitation Enhancement Over Tasmania

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The orographic precipitation enhancement (OPE) generated within wintertime post‐frontal air masses is a prominent climate feature of Tasmania. This study investigates a passage of a cold sector of a mid‐latitude cyclone over the Southern Ocean (SO) and Western Tasmania (WTAS) observed from 2100 UTC 11 July to 0300 UTC 13 July.

Subseasonal Tropical Convection Characteristics in the Energy Exascale Earth System Model Version 2

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Accurate simulation of subseasonal tropical moist convection remains a key challenge for Earth system models. The difficulties stem from the reliance of cumulus cloud processes on model parameterizations and the need to represent the multiscale nature of interactions among clouds, radiation, moisture, circulation, and surface energy fluxes ...

A First Look at the Global Climatology of Low‐Level Clouds in Storm Resolving Models

Journal of Advances in Modeling Earth Systems
The representation of subtropical stratocumulus and trade‐wind cumulus clouds by preliminary versions of Integrated Forecasting System (IFS) and ICON km‐scale global coupled climate models is explored.

The Role of Sea Breeze in the Coastal Stratocumulus Dissipation Transition in Antofagasta and San Diego

Atmosphere
Coastal Stratocumulus clouds have a diurnal cycle influenced by solar heating and sea-breeze dynamics. These clouds typically thin after sunrise, and some of them fragment and then dissipate, a transition that has proven difficult to predict.

Trends and Sensitivities of Low‐Cloud Cover and Top Height From Spaceborne Lidar Observations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low clouds effectively cool the Earth by reflecting incoming solar radiation. Detecting low‐level clouds with passive satellite sensors can be ambiguous, whereas active remote sensing instruments directly measure cloud‐top height. Here, we analyze 14 years of spaceborne lidar observations to assess trends in the occurrence of low‐level clouds ...
