New mathematical and statistical tools were developed, standard techniques were refined, classical problems were varied. Applied to the established conceptual models of GFD we got more clarity on the dynamics of oceans and atmospheres. Furthermore, classical models have been improved without becoming untractable from a theoretical point of view. Last but not least, concepts from other branches of science were introduced. GFD models can describe a wide variety of atmospheric and oceanic flows, ranging from planetary- to small-scale from interdecadal to microturbulence time scales. The session primarily focuses on large scale dynamics, however, it might be a forum for discussion of other aspects of theoretical GFD too. In 2004 we honored Hans Ertel's 100-year jubilee with a number of talks on potential vorticity. Another fundamental quantity in GFD is energy. A year before Ertel's birth, the austrian scientist Max Margules published a seminal paper on the energetics of storms. In 1955, Edward Lorenz has refined Margules' work and implemented available potential energy as a tool for studying atmospheric energetics. In honor of these scientists we particularily encourage contributions on novel aspects of the energy and potential vorticity use in atmospheric and oceanic dynamics.
