Southern Extratropical Cyclone Behavior in ECMWF Analyses during the FROST Special Observing Periods
Publisher: American Meteorological Society
Abstract: The data collected during the three special observing periods (SOPs) of the Antarctic First Regional Observing Study of the Troposphere project provide an excellent base upon which to study the behavior of cyclonic systems ...
A Curvilinear Ocean Model Using a Grid Regionally Compressed in the South Indian Ocean
Publisher: American Meteorological Society
Abstract: It is shown that a global curvilinear grid with variable resolution is an efficient way of providing a high density of grid points in a particular region. In equilibrium experiments using asynchronous time steps, this type ...
Influences of Topography on the Modeling of Abyssal Water Masses. Part I: Effects of Channel Representation
Publisher: American Meteorological Society
Abstract: Connections between basins below 4000 m, which may or may not be resolved in computer-generated model topography, have been found to have a considerable impact on the movement of Antarctic Bottom Water and on deep ocean ...
Influences of Topography on the Modeling of Abyssal Water Masses. Part II: Spurious Extrema
Publisher: American Meteorological Society
Abstract: Unphysical extrema are found in ocean simulations employing space-centered advection even when horizontal mixing coefficients are sufficient to suppress checkerboard behavior. They are mostly found as isolated spurious ...
