Prognostic equation

From Wikipedia, the free encyclopedia

Prognostic equation - in a physical (and especially geophysical) simulation context is a prognostic equation predicts variables for some time in the future on the basis of the values at the current or previous times.

For instance, the well-known Navier-Stokes equations that describe the time evolution of a fluid are prognostic equations that predict the future distribution of velocities in that fluid on the basis of current fields such as the pressure gradient.
