## numerical forecasting

(

*Also called*mathematical forecasting, dynamical forecasting, physical forecasting, numerical weather prediction.) The integration of the governing equations of hydrodynamics by numerical methods subject to specified initial conditions.Numerical approximations are fundamental to almost all dynamical weather prediction schemes since the complexity and nonlinearity of the hydrodynamic equations do not allow exact solutions of the continuous equations.
