摘要: 根据热带印度洋和热带太平洋(22.5°S~22.5°N,42.5°E~77.5°W)1951~1995年逐月5°×5°的海面温度距平资料,首先进行了海面温度距平的平均功率谱分析,获取赤道印度洋和赤道太平洋海面平均温度距平存在准12年和准4年的周期变化;然后,利用多维时间序列的交叉谱分析,进一步分别分析了赤道印度洋和赤道太平洋各格点上海面温度距平在准12年和准4年演变周期各格点之间的演变位相及演变落后时间,获得一些有意义的结论。Abstract: With to the 5°×5°sea surface temperature anomaly data about the tropical India Ocean and the tropical Pacific(22.5°S~22.5°N,42.5°E~77.5°W)from 1951 to 1995, the average power spectral was first analyzed for the sea surface temperature anomaly data. The results show that there are quasi-12-yr. and quasi-4-yr. oscillation periods for the sea surface temperature anomaly data about the tropical India Ocean and the tropical Pacific. Thereafter, the covariant spectral and time-lag spectral in the 12-yr. and 4-yr. oscillation periods are further analyzed with the cross power spectral analysis for multiple dimension time series. Some significant results are obtained.
