| Abstract | The significance of year-round relationships between synoptic storm activity and sea-surface temperature (SST) over the North Pacific Ocean for the period January 1969 through December 1978, were examined using cross-correlation analysis. The possible existence of a seasonal dependence in the SST-wind relationships was examined using sub-sample record cross-correlation analysis and model tests with both a constant and a variable mixed-layer depth, respectively. Wind forcing data was repre3 sented by (U,), friction velocity cubed, and wind stress curl (CURL ZT), as computed from: (a) High-pass filtered wind components only (periods less than ten days), (b) Highand Low-pass filtered wind components which includes the interaction terms and (c) the unfiltered (total) wind components.. 3 3 The correlation maps of SST with both (U*)H and (U*)HL, calculated from the ten-year record, showed large areas of significant negative values in the midlatitude North Pacific Ocean when the SST was lagged by 3 any amount from zeroto three-months. Lag correlations involving (U*) from (c) and (CURL zT) were considerably less significant. Zero lag correlations between a/;t SST and the various wind parameters generally substantiated the above results except for revealing a large and significant positive correlation between @/at SST and the (CURL zT) (from (c) off the West Coast of North America. The sub-sample record examination resulted in generally low significance levels and no statistical confidence as to the existence of a seasonal variation in the relationships. Model tests involving a prescribed, seasonally varying, mixed-layer depth showed that there was no detectable seasonal variation in the SST-wind relationships. |
