Plate 2 (a) TOPEX/POSEIDON sea surface height anomaly. Horizontal axis is time and the scale is the same for all the panels of Plate 2. (b) Time series of NSCAT zonal wind speed at 147°E. (c) Zonal current at 147°E. Low pass filter of cutoff period at 10 days were applied to the data for this and following panels except (h) and (i). (d) Isotherm at 147°E. Contour interval is l℃. (e) Meridional current at 147°E. (f) Zonal current at 156°E. (g) Isotherm at 156°E. (h) Pseudo zonal wind stress observed by NSCAT and averaged from December 15 through 31 1996. (i) Same as (h) except it is averaged from March 1 through 20 1997.
