متن کاملA Semi-lagrangian Approach to the Shallow Water Equations
We present a formulation of the shallow water equations that emphasizes the conservation of potential vorticity. A locally conservative semi-Lagrangian time-stepping scheme is developed, which leads to a 593 https://ntrs.nasa.gov/search.jsp?R=19940017007 2017-12-03T14:09:29+00:00Z
متن کاملA Semi-implicit Semi-lagrangian Shallow-water Model for Massively Parallel Processors
The formulation of a grid point shallow-water model proposed by C^ ot e and Stan-iforth is described. The model employs a hybrid nite-volume//nite-element spatial discretisation on a staggered Arakawa B type grid, where the geopoten-tial is computed at grid points and the wind u is found at grid cell centers. Time integration is based upon a two-time-level semi-implicit, semi-Lagrangian scheme....
متن کاملA Semi-Implicit Semi-Lagrangian Finite-Element Shallow-Water Ocean Model
The nite-element, semi-implicit, and semi-Lagrangian methods are combined together to solve the shallow-water equations using unstructured triangular meshes. Triangular nite elements are attractive for ocean modeling because of their exibility for representing irregular boundaries and for local mesh re nement. A \kriging" interpolator is used for the semi-Lagrangian advection, leading to an acc...
