This animation runs at a quarter of the speed as Clip 1 and has twice the temporal resolution that allows for  a careful examination of the high-latitude, high-frequency fluctuations. The period corresponds to that of the double Kelvin wave that preceded the El Nino/La Nina event (See Clip 1 caption for details.)
What appears as "flickering" in Clip 1 can now be seen as a continuous fluctuation. Variations in the Southern Ocean display a tendency of eastward propagation reflecting the predominant pathway of storms. Topographic influence is evidenced by abrupt changes near topographic boundaries, such as near the Mid Ocean Ridge   south of New Zealand and Australia. Coherent changes are also evident over the Bellingshausen Basin.
Although not as energetic (fast oscillating) as the model, it is interesting to note some evidence of coherence between the model's high frequency fluctuations and anomalies mapped from TOPEX/POSEIDON. Particular examples can be seen in the southern Indian Ocean (February '97) and the Bellingshausen Sea (January '97).
