RISHigh-Resolution Simulation of Shallow-to-Deep Convection Transition over Land
Publisher: American Meteorological Society
Abstract: Results are presented from a high-resolution three-dimensional simulation of shallow-to-deep convection transition based on idealization of observations made during the Large-Scale Biosphere?Atmosphere (LBA) experiment in ...
A New Cloud Physics Parameterization in a Large-Eddy Simulation Model of Marine Stratocumulus
Publisher: American Meteorological Society
Abstract: A new bulk microphysical parameterization for large-eddy simulation (LES) models of the stratocumulus-topped boundary layer has been developed using an explicit (drop spectrum resolving) microphysical model as a data source ...
Thermodynamic Constraints on the Morphology of Simulated Midlatitude Squall Lines
Publisher: American Meteorological Society
Abstract: his study examines how environmental thermodynamics constrain the morphology of simulated idealized midlatitude squall lines (SLs). The thermodynamic soundings used for simulating various SLs are specified primarily by ...

Publisher: American Meteorological Society
Abstract: AbstractSubdaily temperature and precipitation extremes in response to warmer SSTs are investigated on a global scale using the superparameterized (SP) Community Atmosphere Model (CAM), in which a cloud-resolving model is ...
Evaluation of the Simulated Interannual and Subseasonal Variability in an AMIP-Style Simulation Using the CSU Multiscale Modeling Framework
Publisher: American Meteorological Society
Abstract: The Colorado State University (CSU) Multiscale Modeling Framework (MMF) is a new type of general circulation model (GCM) that replaces the conventional parameterizations of convection, clouds, and boundary layer with a ...
Similarity of Deep Continental Cumulus Convection as Revealed by a Three-Dimensional Cloud-Resolving Model
Publisher: American Meteorological Society
Abstract: A three-dimensional cloud-resolving simulation of midlatitude continental convection during the Atmospheric Radiation Measurement (ARM) program summer 1997 intensive observation period (IOP) is used to study the similarity ...
Cloud Resolving Modeling of the ARM Summer 1997 IOP: Model Formulation, Results, Uncertainties, and Sensitivities
Publisher: American Meteorological Society
Abstract: A new three-dimensional cloud resolving model (CRM) has been developed to study the statistical properties of cumulus convection. The model was applied to simulate a 28-day evolution of clouds over the Atmospheric Radiation ...
Simulations of the Atmospheric General Circulation Using a Cloud-Resolving Model as a Superparameterization of Physical Processes
Publisher: American Meteorological Society
Abstract: Traditionally, the effects of clouds in GCMs have been represented by semiempirical parameterizations. Recently, a cloud-resolving model (CRM) was embedded into each grid column of a realistic GCM, the NCAR Community ...
A Large Eddy Simulation Model with Explicit Microphysics: Validation against Aircraft Observations of a Stratocumulus-Topped Boundary Layer
Publisher: American Meteorological Society
Abstract: A new dynamical framework for the Cooperative Institute for Mesoscale Meteorological Studies large eddy simulation model (CIMMS LES) with an explicit microphysics scheme is developed. It is shown that simulation results ...
Virtual Field Campaigns on Deep Tropical Convection in Climate Models
Publisher: American Meteorological Society
Abstract: High-resolution time?height data over warm tropical oceans are examined, from three global atmosphere models [GFDL?s Atmosphere Model 2 (AM2), NCAR?s Community Atmosphere Model, version 3 (CAM3), and a NASA Global Modeling ...
