Abstract
This article examines some general atmospheric circulation and climate models in the context of the notion of “memory”. Two kinds of memories are defined: statistical memory and deterministic memory. The former is defined through the autocorrelation characteristic of the process if it is random (chaotic), while for the latter, a special memory function is introduced. Three of the numerous existing models are selected as examples. For each of the models, asymptotic (att → ∞) expressions are derived. In this way, the transients are filtered out and that which remains concerns the final behaviour of the models.
