Idealized model for stratocumulus cloud layer thickness

Tellus A: Dynamic Meteorology and Oceanography, 1989
Equilibrium solutions are constructed using an idealized model for mixed and partially mixed boundary layers to show the dependence of the equilibrium cloud layer thickness on different physical processes. The condition when a mixed layer becomes cloud-free is reduced to a comparison between three pressure scales, associated with the surface wind and ...

Investigating the sign of stratocumulus adjustments to aerosols in the ICON global storm-resolving model [PDF]

Atmospheric Chemistry and Physics
Aerosols can cause brightening of stratocumulus clouds, thereby cooling the climate. Observations and models disagree on the magnitude of this cooling, partly because of the aerosol-induced liquid water path (LWP) adjustment, with climate models ...

CGILS: Results from the First Phase of an International Project to Understand the Physical Mechanisms of Low Cloud Feedbacks in Single Column Models [PDF]

1] CGILS-the CFMIP-GASS Intercomparison of Large Eddy Models (LESs) and single column models (SCMs)-investigates the mechanisms of cloud feedback in SCMs and LESs under idealized climate change perturbation. This paper describes the CGILS results from 15

Microphysical properties of stratocumulus clouds during ACE-2

Tellus B, 2000
Microphysical measurements performed during 8 flights of the CLOUDYCOLUMN component of ACE-2, with the Meteo-France Merlin-IV, are analyzed in terms of droplet number concentration and size. The droplet concentration is dependent upon the aerosol properties within the boundary layer.

DNS and LES for Simulating Stratocumulus: Better Together

Journal of Advances in Modeling Earth Systems, 2018
We argue that combining direct numerical simulation (DNS) with large‐eddy simulation (LES) and field studies could accelerate current lines of stratocumulus research.

Competing Effects of Droplet Sedimentation and Wind Shear on Entrainment in Stratocumulus

Journal of Advances in Modeling Earth Systems, 2019
The joint effect of droplet sedimentation and wind shear on cloud top entrainment in stratocumulus is investigated with direct numerical simulations. Although it is well understood that droplet sedimentation weakens entrainment while wind shear enhances ...

Low cloud investigations for project FIRE: Island studies of cloud properties, surface radiation, and boundary layer dynamics. A simulation of the reflectivity over a stratocumulus cloud deck by the Monte Carlo method [PDF]

The radiation field over a broken stratocumulus cloud deck is simulated by the Monte Carlo method. We conducted four experiments to investigate the main factor for the observed shortwave reflectively over the FIRE flight 2 leg 5, in which reflectivity ...

A modeling study of marine boundary layer clouds [PDF]

Marine boundary layer (MBL) clouds are important components of the earth's climate system. These clouds drastically reduce the amount of solar radiation absorbed by the earth, but have little effect on the emitted infrared radiation on top of the ...
