Approved for public release, distribution is unlimited / Empirical Orthogonal Function (EOF) and cross-correlation analysis were used to examine the interrelationship between anomalous wind forcing and anomalous sea surface temperature (SST) over the North Pacific Ocean for the period January 1969 through December 1978. Wind forcing was represented by u*3, friction velocity cubed, and curlzt, wind stress curl, as computed from: a) high-pass filtered (periods less than ten days) wind components only, b) a combination of high- and low-pass (periods greater than ten days) filtered wind components, and c) the unfiltered (total) wind components. EOF analysis was applied to the monthly anomalies to extract "signal" from "noise". Lag correlation analysis was used to investigate the relations between anomalous wind values and SST. Its was found that both u*3 and curlzt correlation maps show significant increases in correlations at zero and plus-one-month lag..(Large areas of the North Pacific Ocean were correlated at the 32% significance level and several smaller for u*3 than for curlzt and stronger for the storm-related (filtered) parameters.
