Using the Sensitivity of Large-Eddy Simulations to Evaluate Atmospheric Boundary Layer Models
Publisher: American Meteorological Society
Abstract: simple framework to study the sensitivity of atmospheric boundary layer (ABL) models to the large-scale conditions and forcings is introduced. This framework minimizes the number of parameters necessary to describe the ...
Time Scales of the Trade Wind Boundary Layer Adjustment
Publisher: American Meteorological Society
Abstract: he adjustment of the trade wind atmospheric boundary layer to an abrupt sea surface warming is investigated using a large-eddy simulation (LES) and two simple bulk models: a mixed-layer model (MLM), and a model based on ...
Convective Entrainment and Large-Scale Organization of Tropical Precipitation: Sensitivity of the CNRM-CM5 Hierarchy of Models
Publisher: American Meteorological Society
Abstract: he spurious double intertropical convergence zone (ITCZ) is a systematic bias affecting state-of-the-art coupled general circulation models (GCMs). Modeling studies show that the ITCZ structure is very sensitive to moist ...
On Bulk Models of Shallow Cumulus Convection
Publisher: American Meteorological Society
Abstract: Two-layer bulk models of the cloudy boundary layer are investigated, focusing on the consistency issues between common assumptions on the turbulent mixing and the thermodynamic profiles. Simplifications of the vertical ...

Poleward-Propagating Intraseasonal Monsoon Disturbances in an Intermediate-Complexity Axisymmetric Model
Publisher: American Meteorological Society
Abstract: A model of intermediate complexity based on quasi-equilibrium theory?a version of the quasi-equilibrium tropical circulation model with a prognostic atmospheric boundary layer, as well as two free-tropospheric modes in ...
Scale Sensitivity of the Gill Circulation. Part II: Off-Equatorial Case

The Effect of Imposed Drying on Parameterized Deep Convection
Publisher: American Meteorological Society
Abstract: This paper examines the influence of imposed drying, intended to represent horizontal advection of dry air, on parameterized deep convection interacting with large-scale dynamics in a single-column model framework. Two ...
Multiple Equilibria of the Hadley Circulation in an Intermediate-Complexity Axisymmetric Model
Publisher: American Meteorological Society
Abstract: A model of intermediate complexity based on quasi-equilibrium theory?a version of the Quasi-Equilibrium Tropical Circulation Model with a prognostic atmospheric boundary layer, as well as two free-tropospheric modes in ...
