Presentations of EOF – Correlation Map
q Another way to present EOF is to correlate the principal
component of an EOF with the original time series at each
data point.
q This way, present the EOF structure in a correlation map.
q  In this way, the correlation map tells you what are the co-
varying part of the variable (for example, SST) in the
spatial domain.
q In this presentation, the EOF has no unit and is non-
dimensional.
