RISThe Primitive Equations in the Stochastic Theory of Adiabatic Stratified Turbulence
Publisher: American Meteorological Society
Abstract: The stochastic theory of compressible turbulent fluid transport recently developed by Dukowicz and Smith is applied to the ensemble-mean primitive equations (PEs) for adiabatic stratified flow. The theory predicts a ...
Multiscale Overview of a Violent Tornado Outbreak with Attendant Flash Flooding
Publisher: American Meteorological Society
Abstract: On 1 March 1997 violent tornadoes caused numerous fatalities and widespread damage across portions of central and eastern Arkansas and western Tennessee. In addition, the associated thunderstorms produced very heavy rainfall ...
Anisotropic Gent–McWilliams Parameterization for Ocean Models
Publisher: American Meteorological Society
Abstract: An anisotropic generalization of the Gent?McWilliams (GM) parameterization is presented for eddy-induced tracer transport and diffusion in ocean models, and it is implemented in an ocean general circulation model using a ...
Global Ocean Circulation from Satellite Altimetry and High-Resolution Computer Simulation
Publisher: American Meteorological Society
Abstract: The sea surface elevation relative to the geoid, a dynamic boundary condition for the three-dimensional oceanic pressure field, is being determined over the global ocean every 10 days by a precision radar altimeter aboard ...
A Reformulation and Implementation of the Bryan-Cox-Semtner Ocean Model on the Connection Machine
Publisher: American Meteorological Society
Abstract: Certain aspects of the Semtner-Chervin version of the Bryan-Cox-Semtner global ocean model are reformulated for improved efficiency on parallel computer architectures and on the Connection Machine CM-2 in particular. These ...
On the Mixing Coefficient in the Parameterization of Bolus Velocity
Publisher: American Meteorological Society
Abstract: Mesoscale eddies in the ocean play an important role in the ocean circulation. In order to simulate the ocean circulation, mesoscale eddies must be included explicitly or parameterized. The eddy permitting calculations of ...
Numerical Simulation of the North Atlantic Ocean at 1/10°
Publisher: American Meteorological Society
Abstract: In this paper an initial analysis of an 0.1° simulation of the North Atlantic Ocean using a level-coordinate ocean general circulation model forced with realistic winds covering the period 1985?96 is presented. Results are ...
Isoneutral Diffusion in a z-Coordinate Ocean Model
Publisher: American Meteorological Society
Abstract: This paper considers the requirements that must be satisfied in order to provide a stable and physically based isoneutral tracer diffusion scheme in a z-coordinate ocean model. Two properties are emphasized: 1) downgradient ...
The Evolution and Impact of a Meteorological Outreach Program for Public Safety Officials: An Update on the Oklahoma Mesonet’s OK-First Program
Publisher: American Meteorological Society
Abstract: AbstractSince 1997, the Oklahoma Mesonet (the state?s automated mesoscale weather station network) has served a community of more than 1,400 public safety officials (emergency managers, fire officials, law enforcement, ...
The Community Climate System Model Version 3 (CCSM3)
Publisher: American Meteorological Society
Abstract: The Community Climate System Model version 3 (CCSM3) has recently been developed and released to the climate community. CCSM3 is a coupled climate model with components representing the atmosphere, ocean, sea ice, and land ...
