RISA Mixed Scheme for Subgrid-Scale Fluxes in Cloud-Resolving Models
Publisher: American Meteorological Society
Abstract: A large-domain large-eddy simulation of a tropical deep convection system is used as a benchmark to derive and test a mixed subgrid-scale (SGS) scheme for scalar and momentum fluxes in cloud-resolving models (CRMs). The ...
Sensitivity of Climate to Changes in NDVI
Publisher: American Meteorological Society
Abstract: The sensitivity of global and regional climate to changes in vegetation density is investigated using a coupled biosphere?atmosphere model. The magnitude of the vegetation changes and their spatial distribution are based ...
Effects of Implementing the Simple Biosphere Model in a General Circulation Model
Publisher: American Meteorological Society
Abstract: The Simple Biosphere Model (SiB) of Sellers et al. was designed to simulate the interactions between the Earth's land surface and the atmosphere by treating the vegetation explicitly and realistically, thereby incorporating ...
A Revised Land Surface Parameterization (SiB2) for Atmospheric GCMS. Part I: Model Formulation
Publisher: American Meteorological Society
Abstract: The formulation of a revised land surface parameterization for use within atmospheric general circulation models (GCMs) is presented. The model (SiB2) incorporates several significant improvements over the first version ...
Modeling a Stratocumulus-Topped PBL: Intercomparison among Different One-Dimensional Codes and with Large Eddy Simulation
Publisher: American Meteorological Society
Abstract: Several one-dimensional (1D) cloud/turbulence ensemble modeling results of an idealized nighttime marine stratocumulus case are compared to large eddy simulation (LES). This type of model intercomparison was one of the ...
Scientific Investigations Planned for the Lidar In-Space Technology Experiment (LITE)
Publisher: American Meteorological Society
Abstract: The Lidar In-Space Technology Experiment (LITE) is being developed by NASA/Langley Research Center for a series of flights on the space shuttle beginning in 1994. Employing a three-wave-length Nd:YAG laser and a 1-m-diameter ...
A Revised Land Surface Parameterization (SiB2) for GCMS. Part III: The Greening of the Colorado State University General Circulation Model
Publisher: American Meteorological Society
Abstract: SiB2, the second-generation land-surface parameterization developed by Sellers et al., has been incorporated into the Colorado State University general circulation model and tested in multidecade simulation. The control ...
