Abstract:

We first describe a recent field experiment which is intended to develop a climatology for sea state and sea ice in the Beaufort-and Chukchi Seas, to identify factors affecting the spatial and temporal variability of sea state, and to improve forecasting of waves and the marginal ice zone. We then provide adevelopment and applications of improved theory and models for wave-ice interactions, for use in marine synoptic forecast models and Arctic system models. Finally, on seasonal time scales, we provide a description of the linkage between atmospheric and oceanic dynamics, and how these processes can relate to summer sea ice retreat and autumn ice advance.

Biography:

Prof. William Perrie is Senior Research Scientist at Bedford Institute of Oceanography and Adjunct Professor of Dalhousie University, Canada. He graduated from MIT with a Ph.D. degree in Meteorology & Oceanography in 1979. His research involves processes at the atmosphere-ocean interface: numerical modeling of wind waves, air-sea interactions, surface currents, wave-ice and wave-current interactions, coupled wave-atmosphere-ocean models, and remote sensing of wind, waves, sea ice and ocean surface features. Regions of interest are the Northwest Atlantic, and the Arctic.
