Subsurface Equatorial Pacific Temperatures
section of ocean temperature (top) and ocean temperature anomalies
(bottom). Contour interval is 1C. Dashed contours in bottom panel
indicate negative anomalies. Data are derived from the NCEP's global
ocean data assimilation system which assimilates oceanic observations
into an oceanic GCM (Behringer, D. W., and Y. Xue, 2004: Evaluation of the global
ocean data assimilation system at NCEP:
The Pacific Ocean. AMS 84th Annual Meeting, Seattle, Washington, 11-15).
Anomalies are departures from the 1991-2020 base period means.
