Fig. 5From: Wind-driven decadal sea surface height and main pycnocline depth changes in the western subarctic North PacificLongitudinal distributions of a the mean value and b the standard deviation of Wm (10−6 m s−1) in Eq. (6). Values of the first (m=1), second (m=2), third (m=3), and fourth (m=4) modes are shown by black, red, green, and blue lines, respectively. In panel a, the mean residual error (10−6 m s−1) of the Ekman pumping velocity, wE, for the four meridional modes is indicated by a dashed lineBack to article page
