We show that variations in GS position, strength, and meandering status are the dominant spatiotemporal modes in regional SSH variability as they explain over 50% of the total variance. In particular, meridional shift of the GS associated with the large-scale wind variation over the North Atlantic contributes to approximately 30% of SSH variability. We further find that this path displacement mode can drive approximately 15% of regional mesoscale variability in eddy kinetic energy and divergent eddy heat flux. This observational-based evidence of ocean mesoscale response to GS shift infers a potentially important forcing mechanism that could drive eddy-scale ocean variability and has far-reaching implications for regional ocean and ecosystem dynamics in response to climate variation.
