The seasonal-to-decadal (s2d) experiments comprise two sets of simulations: the so-called Stream 1 and Stream 2 simulations. For both streams, coordinated forecast experiments over seasonal, interannual and decadal timescales have been performed. Three different approaches are being pursued to represent model uncertainties: the multi-model approach, the perturbed physical parameter approach and the stochastic physics approach.
The European-funded ENSEMBLES project defined two experimental protocols:
The first (stream 1), is essentially a set of test integrations, covering the 11 years 1991-2001 and with May and November start dates only. The second, stream 2, is essentially equivalent to the CHFP protocol.
