Figure S5. Top panel is the BMUs for the climatological
velocity (red line), repeated each year of the time series for
comparison, and the BMUs for the instantaneous velocity (blue line) over
1994–2018. The middle panel is a histogram of the difference between
the two BMUs in the top panel. The bottom panel is each year’s sum of
differences other than zero, the sum of the histogram in the second
panel; the green line is the 1994–2018 average.
Table S1. Correspondence between the HYCOM climatology (HC)
SOMs spatial patterns and the HYCOM instantaneous (HI) SOMs spatial
patterns based on the highest correlation between the directions (angle)
of each spatial pattern with another (see Figure S4).
