# Model

From Glossary of Meteorology

## model

A tool for simulating or predicting the behavior of a dynamical system like the atmosphere.

Models can be based on subjective heuristic methods, statistics (

*see*statistical dynamical model, model output statistics), numerical methods (*see*numerical forecasting), simplified physical systems (*see*dishpan experiments), analogy (*see*analogs), etc. The term is now most commonly applied to numerical models.
