A retrospective analysis or re-analysis of the state of a dynamical system with the aid of a numerical model. In contrast to forecasts where observations are available only for the initialization of the forecast, they are generally known for the entire hindcast period and may assimilated any time in the course of the production of the hindcast. Hindcast are sometimes also referred to as reconstructions.

A technique to answer question of the type “What happens if ….?” Usually some assumptions such as about e.g. the development of future greenhouse gas concentrations are made and the subsequently the consequences of these developments are studied with the aid of numerical models. The latter process is frequently called projections. Scenarios are thus tools to study the sensitivity of a system to a range of prescribed future developments.
