Long's Equation in Terrain Following Coordinates
Long’s equation describes two dimensional stratified atmospheric flow over terrain which is represented by the geometry of the domain. The solutions of this equation over simple topography were investigated analytically and numerically by many authors. In this paper we derive a new terrain following formulation of this equation which incorporates the terrain as part of the differential equation...
متن کاملOcean forecasting in terrain-following coordinates: Formulation and skill assessment of the Regional Ocean Modeling System
Systematic improvements in algorithmic design of regional ocean circulation models have led to significant enhancement in simulation ability across a wide range of space/time scales and marine system types. As an example, we briefly review the Regional Ocean Modeling System, a member of a general class of three-dimensional, free-surface, terrain-following numerical models. Noteworthy characteri...
متن کاملPotential vorticity 1
LTEX source, defined here to print as italic. Possible cross-references to other articles are flagged \crossref{...}. For visibility, \crossref{...} is temporarily defined to print as sans-serif. Therefore, sans-serif italic signals both a new term and a possible cross-reference. I have used \openingscarequote...\closingscarequote in a few places. This bends the house-style rules, but unfortuna...
متن کاملExplicitly computing geodetic coordinates from Cartesian coordinates
This paper presents a new form of quartic equation based on Lagrange’s extremum law and a Groebner basis under the constraint that the geodetic height is the shortest distance between a given point and the reference ellipsoid. A very explicit and concise formulae of the quartic equation by Ferrari’s line is found, which avoids the need of a good starting guess for iterative methods. A new expli...
متن کاملPotential Vorticity as Meridional Coordinate
The dynamical equations of atmospheric flow are written using potential vorticity as the meridional coordinate and potential temperature as the vertical coordinate. Within this system, the atmosphere is divided into undulating tubes bounded by isentropic and constant potential vorticity surfaces, and, under adiabatic and frictionless conditions, the air moves through the tubes without penetrati...
