A distinctive difficulty in climatesystem modeling, analysis and prediction is the presence of two or more time scales in the problem. The atmosphere and oceans each support slow Rossby and fast inertiagravity waves, while the characteristic times of atmosphere, oceans, and ice sheets are about a factor of 10 apart. Thus the proper treatment, via slavedvariable and slowmanifold theory of timescale disparity within each subsystem and between subsystems is of the essence. The workshop topics will include
(i) the connection between the slow manifold, averaged descriptions, the quasigeostrophic approximation, and intermediate balanced models;
(ii) models of the coupled oceanatmosphere system; and
(iii) slowmanifold theory. Tools such as asymptotics, averaging, center manifold, inertial manifold, attractors and their approximations are indispensable for dealing with these problems.
Keywords: coupling, ENSO, intermediate models
