Climate system modeling program. Annual report, September 1, 1991--August 31, 1992

The CSMP proposal to NSF contained a description of a project to examine variability of the climate system on decadal-to-contennial time scales, with an emphasis on eventually understanding the processes which led to climate variability over the past one to two centuries as a basis for validating models of potential future changes. The project thus focused first, on understanding, and second on understanding as a basis for the development of validation procedures for models intended for use in climate change applications. The principal activity of the first year of the project was a workshop on one of the major sources of interdecadal variability-the thermohaline circulation (THC) of the oceans. This workshop was focused on review of the cutting edge science of the THC, and on identification of opportunities for future research. The workshop report is attached
