Cloud‐aerosol interactions for boundary layer stratocumulus in the Lagrangian Cloud Model
Journal of Geophysical Research: Atmospheres, 2010 Lagrangian Cloud Model (LCM) is a mixed Eulerian/Lagrangian approach to atmospheric large eddy simulation (LES), with two‐way coupling between Eulerian dynamics and thermodynamics and Lagrangian microphysics. Since Lagrangian representation of microphysics does not suffer from numerical diffusion in the radius space and solves full droplet growth ...

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. This is caused by the formulation of the turbulent length scale / in terms of the moist Richardson number, which gives unrealistic results in the case of low ...

Coupled Map Modeling for Cloud Dynamics [PDF]
, 1996 A coupled map model for cloud dynamics is proposed, which consists of the successive operations of the physical processes; buoyancy, diffusion, viscosity, adiabatic expansion, fall of a droplet by gravity, descent flow dragged by the falling droplet, and

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 ...

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 ...

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 ...
