对Ｇｅｏｓａｔ高度计ＥＲＭＴ２ＣＤＲｓ共２．３ａ的海面高度数据进行了处理，研究区域为西北太平洋１０°～４５°Ｎ、１２０°～１６０°Ｅ，包括整个黑潮流系，时间段为１９８６年１１月至１９８９年３月．经过数据筛选、地球物理、环境因子校正及轨道误差较正后，用客观分析方法得到时空均匀的５０个时间序列的海面高度异常场。Ｇｅｏｓａｔ高度计的海面高度异常与验潮站实测水位高度符合较好，这证明处理结果是可信的。海面高度异常值均方场表示黑潮变异的能量分布，它与黑潮的弯曲及地形有关。
The Geosat altimeter ERMT2CDRs were processed for a total of 2.3 years of sea surface height data from 10 ° ~45 ° N and 120 ° ~160 ° E over the NW Pacific, including the entire Kuroshio current system from November 1986 to 1989 In March. After data screening, geophysical, environmental factor correction and orbit error correction, 50 spatiotemporal sea level anomaly fields obtained by objective analysis are obtained. The sea level anomaly of the Geosat altimeter is in good agreement with the measured water level of the tide gauge, which proves the result of the treatment is credible. The mean square sea level anomalies represent the energy distribution of the Kuroshio variation, which is related to the Kuroshio’s curvature and topography.
