From Glossary of Meteorology
The study of the evolution of a time-dependent dynamic system from an equilibrium state A to another equilibrium state B.
The different equilibrium states may be two different equilibrium states of a dynamical system having multiequilibrium states, or different equilibrium states that are due to change(s) in either the internal or the external characteristics of the dynamical system.
