Correlation between temperature at surface layer (0m, 100m, 200m and 400m depth) and sea sm～ face dynamic height is examined in the western North Pacific and its adjacent seas. Multiple correlation coefficients calculated from available hydrographic data exceed 0.9 in the Japan Sea and at the south of 40N in the Pacific, while correlation is lower in the Okhotsk Sea and at the north of 40N in the Pacific. It is found that variation of sea surface dynamic height is almost explained with variation of temperature at surface layer in the Japan Sea and in the western subtropical gyre of the Pacific. Residuals in sea surface dynamic height estimated with multiple linear regression of temperature at surface layer are 4-5cm at 20 35N, 7cm at 35-40N in the Pacific and 2cm in the Japan Sea. It is shown that sea surface dynamic height could be reliably calculated with multiple linear regression of temperature at surface layer for these regions Published
