The three leading EOFs of the global OHCA and their principle components. (a–c) The three leading EOFs of the global upper ocean (top 700 m) heat content, respectively. The maps were created by using the m-map toolbox (https://www.eoas.ubc.ca/~rich/map.html) for Matlab (version R2016b). (d) The PCs (normalized by their respective standard deviations) of the three leading EOFs.
