This paper explores the feasibility of an experimentation strategy for investigating sensitivities in fast components of atmospheric general circulation models.
Development of a parameterization of black carbon aging for use in general circulation models
parameterization of black carbon aging general circulation models
2014/12/16
A parameterization of black carbon (BC) aging in the atmosphere is developed for use in general circulation models (GCMs) that separately treat hydrophobic BC and hydrophilic BC modes but do not expli...
Stokes Transport by Gravity Waves for Application to Circulation Models
Stokes Transport Circulation Models Gravity Waves
2009/3/24
Stokes mass transport by surface gravity waves is related to the often more interesting Lagrangian transport in a manner that is complicated by the earth's rotation. This paper discusses the condition...
Surface Thermal Boundary Condition for Ocean Circulation Models

Mixed Layers Simple Ocean Circulation Models Fronts
2009/2/9
A three-dimensional regime with a differentially heated mixed layer on top of an ideal fluid interior is considered in a situation which corresponds to the interior of the well-known wind-driven model...
Current meter observations in Lake Ontario covering the 140-day period from 4 November 1982 to 23 March 1983 are used to evaluate the performance of circulation models for different time scales. The m...
