Physical oceanography

numerical stability

Earth science; Physical oceanography

In numerical modeling, a numerical computational scheme is said to be stable if the infinite set of computed solutions of the discrete algebraic equations created by the process of discretization of ...

layer coordinates

Earth science; Physical oceanography

In numerical modeling, a system of vertical coordinates where an arbitrary number of layers are specified in which some fluid property (e.g. density) remains constant, i.e. an independent variable. ...

level coordinates

Earth science; Physical oceanography

In numerical modeling, a vertical coordinate system in which a arbitrary number of height or depth levels are specified at which the changing values of the various dependent variables are calculated. ...

pseudospectral method

Earth science; Physical oceanography

In numerical modeling, an approximation which uses interpolating functions to estimate derivatives of fields represented on a grid in physical space. It is so-called because the interpolating ...

diagnostic

Earth science; Physical oceanography

In numerical modeling, an equation is diagnostic if the present value of a dependent variable is calculated from the present value(s) of one or more dependent variables.

prognostic

Earth science; Physical oceanography

In numerical modeling, an equation is prognostic if the future value of a dependent variable is predicted from the present value(s) of one or more dependent variables.

implicit scheme

Earth science; Physical oceanography

In numerical modeling, an integration algorithmthat temporally advances an approximate solution via discrete steps using information from present as well as from previous time steps. These are ...
