Figure 1. (a) Bottom topography map and (b) schematic circulation map in the Northwestern Pacific Ocean, the color shading in Figure 1b corresponds to the annual mean net surface heat flux from the NCEP-NCAR reanalysis data. Labels a–f in Figure 1a represents: a, Shikoku; b, Izu-Ogasawara Ridge; c, Honshu; d, Hokkaido; e, Shatsky Ridge; and f, Emperor Seamounts. The Kuril-Kamchatka Trench (KKT) and the Japan Trench (JT) are represented by white dashed lines. Circula- tion features shown in Figure 1b are the Oyashio current (OY), the Tsugaru Warm Current (TWC), the southward intrusion of the Oyashio (OYI), the Kuroshio Extension (KE), the Kuroshio Bifurcation Front (KBF), and the Shikoku Recirculation Gyre (SRG), the Subarctic Front (SAF), and the Subarctic Boundary (SAB).
