A Terrain-Following Coordinate System-Derivation of Diagnostic Relationships

نویسنده

  • R. A. Pielke
چکیده

Generalized hydrostatic and geostrophic equations can be derived from the equations in the terrain-following framework. The generalized hydrostatic equation permits some non-hydrostatic motions (as obtained from a Cartesian framework) to remain when a non-zero slope exists. Correspondingly, the generalized geostrophic wind permits a horizontal divergent component (in addition to divergence caused by the change of Coriolis parameter with latitude) to occur when the slope angle is not zero.

An analysis of the orthogonal terrain-following vertical grids on reducing the advection errors in the terrain-following coordinate

An orthogonal terrain-following coordinate (OS coordinate) was proposed by Li et al. (2013) to reduce the advection errors in the classic σ-coordinate. The OS coordinate can smooth the vertical layers above the steep terrain as well as create the orthogonal terrain-following grids in the vertical. The idealized advection experiments in Li et al. (2013) validated that the OS coordinate can signi...

Derivation of turbulent energy in a rotating system

Energy equation for turbulent flow in a rotating system was derived in terms of second order correlation tensors, where the correlation tensors were functions of space coordinates, distance between two points and time. To reveal the relationship of turbulent energy between two points, one point was taken as origin of the coordinate system. Due to rotation, the Coriolis force played an important...

Extending the Qualitative Trajectory Calculus Based on the Concept of Accessibility of Moving Objects in the Paths

Qualitative spatial representation and reasoning are among the important capabilities in intelligent geospatial information system development. Although a large contribution to the study of moving objects has been attributed to the quantitative use and analysis of data, such calculations are ineffective when there is little inaccurate data on position and geometry or when explicitly explaining ...

Three-dimensional Magneto-thermo-elastic Analysis of Functionally Graded Truncated Conical Shells

This work deals with the three-dimensional magneto-thermo-elastic problem of a functionally graded truncated conical shell under non-uniform internal pressure and subjected to magnetic and thermal fields. The material properties are assumed to obey the power law form that depends on the thickness coordinate of the shell. The formulation of the problem begins with the derivation of fundamental r...

Derivation of Equation of Motion for the Pillow-Shape Seismic Base Isolation System

Rolling-based seismic isolation systems, in which rollers of circular or non-circular section are used, are less expensive and easier to manufacture. However, this type of isolation suffers from either lack of restoring or re-centering capability, or weakness against uplift forces. To resolve the first shortcoming the use of elliptical as well as pillow-shape rolling parts has been suggested, a...
