Abstract: | 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 dominantly 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.
