位于赤道中西太平洋的九个岛屿站的海平面记录显示了 1974-1975 年至 1981 年期间的海平面趋势，这些趋势由观测到的船风所强制的 Busalacchi 和 O'Brien 线性数值模型很好地预测了。这些趋势的空间格局表明，赤道西太平洋正在失水，而赤道中部太平洋正在增水。这些趋势似乎是由于 1974 年至 1981 年期间中太平洋近赤道东风贸易的显着减弱所致。 1977-1978 年赤道以南岛屿站（拉包尔和霍尼亚拉）海平面的趋势逆转似乎是由于大规模东南贸易强度的类似趋势逆转所致。
The sea level records at the nine island stations located in the western and central equatorial Pacific show trends for the period 1974–1975 to 1981 which are well hindcasted by the linear numerical model of Busalacchi and O'Brien forced by the observed ship winds. The spatial pattern of these trends suggests that the western equatorial Pacific was losing water while the central equatorial Pacific was gaining water. These trends appear to be due to the significant weakening of the near-equatorial easterly trades in the central Pacific which took place throughout the period 1974–1981. The trend reversal observed in 1977–1978 in sea level at the island stations located south of the equator (Rabaul and Honiara) appear to be due to a similar trend reversal in the strength of the large-scale southeast trades.
