 Abstract: The climatic system contains a number of interacting subsystems with natural time scales varying over many orders of magnitude. Deterministic models with realistic spatial resolution can cover only a relatively small band of the total spectrum. Thus a sequence of models is needed for different time-scale ranges, and strategies for coupling together models for different time scales must be devised. A simple example shows that climatic response experiments carried out with models designed only for a single time-scale range (for example an atmospheric GCM) can be quite misleading. A technique for coupling models in which the natural time scales are separated by a spectral gap is described. The theory yields natural climatic variance spectra of approximately the right shape and order of magnitude and provides a basis for designing climatic response experiments with proper consideration of the signal-to-noise problem.
