FIGURE T15. Mean (top) and anomalous
(bottom) depth of the 20°C isotherm for 5°N–5°S in the Pacific
Ocean. Data are derived from the NCEP’s global ocean data assimilation
system which assimilates oceanic observations into an oceanic GCM (Behringer
and Xue, Proceedings of Eighth Symposium on Integrated Observing and
Assimilation Systems for Atmosphere, Oceans, and Land Surface,
Seattle, Washington, 11-15 January 2004). The contour interval is 10 m.
Dashed contours in bottom panel indicate negative anomalies. Anomalies
are departures from the 1981-2010 base period means.
