Modes of Southern Hemisphere Climate Variability & Southern Ocean Panel meeting

Meeting date: June 27-30, 2005
Meeting venue: Scott Polar Research Institute, Cambridge, UK

Modes of southern hemisphere climate variability workshop:

The goals of the workshop were to review the present understanding of the major modes of variability in southern hemisphere climate, the potential for predictability of the climate at mid- to high-latitudes of the southern hemisphere, to identify gaps in our understanding and to discuss field and modelling efforts to fill these gaps.

The talks given at the workshop will be made available as and when permission is given by the speakers. Please ask the speakers before using any material from these presentations and acknowledge as appropriate.
