Re‐Evaluation of Low Cloud Amount Relationships With Lower‐Tropospheric Stability and Estimated Inversion Strength

Geophysical Research Letters, 2022
Lower‐tropospheric stability (LTS) and estimated inversion strength (EIS) have a widely accepted relationship with low cloud amount and are key observational foundations for understanding and modeling low‐level stratiform clouds.

Study of the Aerosol Indirect Effect by Large-Eddy Simulation of Marine Stratocumulus [PDF]

, 2005
A total of 98 three-dimensional large-eddy simulations (LESs) of marine stratocumulus clouds covering both nighttime and daytime conditions were performed to explore the response of cloud optical depth (τ) to various aerosol number concentrations (Na ...

Scaling of Drizzle Virga Depth With Cloud Thickness for Marine Stratocumulus Clouds

Geophysical Research Letters, 2018
Drizzle is frequently observed in marine stratocumulus clouds and plays a crucial role in cloud lifetime and the radiation budget. Most drizzling stratocumulus clouds form drizzle virga below cloud base, where subcloud scavenging and evaporative cooling ...

Influences of an entrainment–mixing parameterization on numerical simulations of cumulus and stratocumulus clouds [PDF]

Atmospheric Chemistry and Physics, 2022
Different entrainment–mixing processes can occur in clouds; however, a homogeneous mixing mechanism is often implicitly assumed in most commonly used microphysics schemes.

Turbulent dispersion in cloud-topped boundary layers [PDF]

, 2009
Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form of Lagrangian particles for four kinds of atmospheric

Factors Controlling Rapid Stratocumulus Cloud Thinning

Journal of the Atmospheric Sciences, 2014
Abstract The relationship between the inversion stability and the liquid water path (LWP) tendency of a vertically well-mixed, adiabatic stratocumulus cloud layer is investigated in this study through the analysis of the budget equation for the LWP.

Multiple‐scale simulations of stratocumulus clouds [PDF]

Journal of Geophysical Research: Atmospheres, 2010
This study introduces a flexible multiple nested modeling framework developed from the Weather Research and Forecasting (WRF) model for boundary layer cloud research. It features a nested large‐eddy simulation in a hindcasting mode that allows a direct comparison between simulations and observations.

Impacts of solar-absorbing aerosol layers on the transition of stratocumulus to trade cumulus clouds [PDF]

Atmospheric Chemistry and Physics, 2017
The effects of an initially overlying layer of solar-absorbing aerosol on the transition of stratocumulus to trade cumulus clouds are examined using large-eddy simulations.

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.

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 ...
