14. The measured sea-surface temperature is obtained as a monthly average of accumulated buoy data from the El Niño 3.4 region. The annual cycle (average) sea-surface temperature data represent the long term monthly average over all observed years. The sea-surface temperature anomaly is therefore the difference between average and measured sea-surface temperature.

28. If a single-fluid model of the ocean with depth H=4000 m had been assumed throughout, then c=√gH≈ 200 m/s. This Tsunami-like speed is clearly absurd for the purposes of this project, and hence the need for the more sophisticated two-fluid model.
