In recent years, much progress has been made in our understanding of the large-scale physical dynamics of Pacific climate variability and change. New modes of ocean and atmospheric variability over the Pacific have been recognized and shown to influence ecosystem processes. The impact that these modes have on marine biophysical interactions in upwelling systems has also become a research focus under a new collaboration between CLIVAR and IMBER, to which PICES is contributing. Diagnosing the mechanisms underlying the statistical correlations between the physical forcing and the ecosystem response strongly relies on our ability to model and synthesize the processes controlling the variability in the climate system, and unveiling the dominant set of physical controls on marine ecosystem dynamics. This synthesis activity is a core component of FUTURE and involves developing low-order (e.g., low number of dimensions) process-models of the climate system, which reduce the complex processes to their most basic and dominant mechanics. Process-models such as these can be used statistically to provide uncertainty estimates of decadal variability in recent historical climate and ecosystem time series, and to provide improved metrics to test the mechanisms of climate variability and change in IPCC models.

This session invites contributions that combine model and observational methods to provide syntheses of the mechanisms controlling North Pacific climate variability, and that show how these improved syntheses enable better diagnosing and predicting of the dynamics of Pacific climate and of the marine ecosystem responses to climate forcing. We also welcome contributions that explore new mechanisms of physical-biological linkages that can only be partially tested with currently available observations, yet provide the theoretical foundation to understand the dynamics of Pacific climate variability and its impact on marine populations, and develop new observational programs. During the session there will be discussion time where the contributors will be asked to participate in developing a synthesis paper on North Pacific climate variability as part of the PICES WG27 activities (http://wg27.pices.int).
