Sensitivity of the Simulated Climate to a Diagnostic Formulation for Cloud Liquid Water
Publisher: American Meteorological Society
Abstract: The accurate treatment of clouds and their radiative properties is widely regarded to be among the most important problems facing global climate modeling. A number of the more serious systematic simulation biases in the ...
Analysis of the Improvement in Implied Meridional Ocean Energy Transport as Simulated by the NCAR CCM3
Publisher: American Meteorological Society
Abstract: The implied meridional ocean energy transport diagnosed from uncoupled integrations of two atmospheric general circulation models?the National Center for Atmospheric Research Community Climate Model versions 2 and 3 (CCM2 ...
Lateral Boundary Conditions for Tropical Cyclone Models
Publisher: American Meteorological Society
Abstract: Under certain circumstances a large fraction of the energy generated by the release of latent heat in a tropical cyclone cab be partitioned to gravity-inertia wave motion rather than to balanced flow. In this way most of ...
Nonlinear Response of Atmospheric Vortices to Heating by Organized Cumulus Convection
Publisher: American Meteorological Society
Abstract: Using an axisymmetric primitive tropical cyclone model, we first illustrate the way in which nonlinear processes contribute to the development of an atmospheric vortex. These numerical experiment show that nonlinearities ...
Transformed Eliassen Balanced Vortex Model
Publisher: American Meteorological Society
Abstract: We consider the axisymmetric balanced flow occurring in a thermally forced vortex in which the frictional inflow is confined to a thin boundary layer. Above the boundary layer the absolute angular momentum ½fR2=rv+½fr2 is ...
Inertial Stability and Tropical Cyclone Development
Publisher: American Meteorological Society
Abstract: We consider the frictionless, axisymmetric, balanced flow occurring in a thermally forced vortex on an f-plane. Following Eliassen (1952) we derive the diagnostic equation for the forced secondary circulation. This equation ...
Assessment of Solution Uncertainties in Single-Column Modeling Frameworks
Publisher: American Meteorological Society
Abstract: Single-column models (SCMs) have been extensively promoted in recent years as an effective means to develop and test physical parameterizations targeted for more complex three-dimensional climate models. Although there are ...
Dynamical Aspects of Twin Tropical Cyclones Associated with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: A nonlinear shallow-water model on the sphere is used to study barotropic aspects of the formation of twin tropical disturbances by Madden?Julian oscillation (MJO) convection. In the model, the effect of MJO convection ...
A Spectral Cumulus Parameterization for Use in Numerical Models of the Tropical Atmosphere
Publisher: American Meteorological Society
Abstract: The spectral cumulus parameterization theory of Arakawa and Schubert is presented in the convective flux form as opposed to the original detrainment form. This flux form is more convenient for use in numerical prediction ...
On Using Global Climate Model Simulations to Assess the Accuracy of MSU Retrieval Methods for Tropospheric Warming Trends
Publisher: American Meteorological Society
Abstract: Climate model simulations of the latter part of the twentieth century indicate a warming of the troposphere that is equal to or larger than the warming at the surface, while satellite observations from the Microwave Sounding ...
