Professor Ted Shepherd
Department of Meteorology of the University of Reading

will give a talk on

"Climate dynamics: the challenge of atmospheric circulation"

The presentation promises a current insight into climate research in the
area of atmospheric dynamics and the Fluctuation-Dissipation Theorem.

The scientific understanding of climate is based almost entirely upon equilibrium concepts of thermodynamics, notably energy balance. However, regional patterns of climate, and climate variability, depend strongly on atmospheric and oceanic circulation, and thus involve dynamics. These aspects of climate remain highly uncertain. Dynamics brings in two major challenges, both of which reflect the nonlinear nature of the climate system: chaotic variability, and the state-dependence of the circulation response to climate forcing. Because the circulation response to external forcing projects strongly onto the modes of chaotic variability, these two major sources of uncertainty are related. This talk will describe a number of ways in which atmospheric circulation reflects these properties, and will suggest that the Fluctuation-Dissipation Theorem may provide a useful approach to address these challenges.
