Observation-OGCM simulation comparison for the annual cycle:
Zonal section of the annual harmonic of vertical isotherm displacement at 4N for the observations and at 2N for the simulation. The phase (top panel) is labelled in months. The amplitude (bottom panel) is in meter and contour interval is every 5 meters. The heavy contour is for January, then dashed contours are February through June, and line contours are July through December. The heavy dashed lines crossing the domain from top to bottom and from east to west are WKB ray paths of the l=1 (or l=2,3) Rossby wave in the background stratification.
