A Cluster Analysis of Pacific Ocean Temperatures and North American Upper Air Temperatures

Abstract

Twenty-two years of summer North Pacific Ocean temperatures were <br /><br />cluster analyzed with fall North American 700 mb air temperatures. Several <br /><br />regional groups were identified on the linkage tree. Most of these groups were <br /><br />aligned in east-west latitudinal bands. One cluster linked both water and air <br /><br />temperatures, suggesting possible teleconnections between ocean and atmosphere.
