Professor Emeritus

Research Interests

Theory of ocean modeling and forecasting; analysis of oceanic data using statistical and dynamic methods; prediction of transient currents in the mid-latitude ocean; interannual variation in the tropical ocean and its effect on climate.

Current Research

Application of methods developed in meteorology and engineering to ocean prediction; validation of these methods with observed and computer-synthesized data; application to prediction of transient currents in the North Pacific.
