摘要
The principal variability patterns (EOF) of the anomalies of total heat transfer from ocean to atmosphere computed from 30 years’ monthly averaged data over the North Pacific Ocean (20-60°N) showed variability was dominated by two patterns : a bipolar pattern and a dominantiy positive or negative pattern depending on the sign of the time series coefficients . The atmosphere contributes greatly to the marine heating anomalies in most of the North Pacific in all seasons. In winter, a positive feedback is formed between the Aleutian Low and the marine heating anomalies; in summer ,the marine heating anomalies are controlled by the heating on the Qinghai - Tibetan Plateau. Both patterns have a winter correlation with the Southern Oscillation Index.
