Large-Eddy Simulation of PBL Stratocumulus: Comparison of Multi-Dimensional and IPA Longwave Radiative Forcing
نویسنده
چکیده
Marine boundary layer (BL) clouds profoundly influence the global shortwave (SW) radiation budget through their effect on albedo, but a significant source of turbulent energy to the BL and the clouds themselves is longwave (LW) cloud top cooling. Cloudy regions can be thought of as radiating as blackbodies in the LW, with a net radiative flux of nearly zero inside the cloud itself and a significant radiative flux divergence within a few tens of meters of the cloud edge.

Bulletin of the American Meteorological Society rameterization schemes for use in general circulation models (GCMs) and (ii) to develop new parameterization schemes based on numerical data generated from large eddy simulations (LESs) or cloud resolving models (CRMs) (Browning 1993). While 3D LESs can explicitly resolve most of the turbulent eddies, CRMs, which resolve only large cloud elements,...
متن کاملCloud droplet sedimentation, entrainment efficiency, and subtropical stratocumulus albedo
[1] The effect of cloud droplet sedimentation on the entrainment rate and liquid water path of a nocturnal nondrizzling stratocumulus layer is examined using largeeddy simulations (LES) with bulk microphysics. In agreement with a prior study by Ackerman et al. (2004), sedimentation is found to decrease entrainment rate and thereby increase liquid water path. They suggested this is due to reduct...
متن کاملLarge-eddy simulation of subtropical cloud-topped boundary layers: 1. A forcing framework with closed surface energy balance
Large-eddy simulation (LES) of clouds has the potential to resolve a central question in climate dynamics, namely, how subtropical marine boundary layer (MBL) clouds respond to global warming. However, large-scale processes need to be prescribed or represented parameterically in the limited-area LES domains. It is important that the representation of large-scale processes satisfies constraints ...
متن کاملLarge-eddy simulation of subtropical cloud-topped boundary layers: 2. Cloud response to climate change
How subtropical marine boundary layer (MBL) clouds respond to warming is investigated using large-eddy simulations (LES) of a wide range of warmer climates, with CO2 concentrations elevated by factors 2–16. In LES coupled to a slab ocean with interactive sea surface temperatures (SST), the surface latent heat flux (LHF) is constrained by the surface energy balance and only strengthens modestly ...
