This memorandum justifies formulas used to analyze wind-driven ocean currents as first-order autoregressive processes forced by the wind. A set of numerical experiments with synthetic data shows that the formulas give accurate results with both white and nonwhite noise forcing and with either filtered or nonfiltered data. The formulas are a significant improvement over those traditionally used in autoregression analysis based on covariances.
