Eddy formations in the ROMS simulation. Snapshots of the plane view for (a–c) SST [°C] in color and SSH as black contours, (d–f) relative vorticity (ζ) at surface and SSH as black contours, and (g–i) density [kg m−3] at 100 m depth in color with horizontal buoyancy gradient (|∇hb|) as black contours. Shading in (a–f) represents the geostrophic velocity higher than 0.5 ms−1, and vertical line remarks 131° E. Three snapshots are for (a, d, g) November 2nd 23:00 h for Eddy-A; (b, e, h) November 13th 19:00 h for Eddy-B; and, (c, f, i) November 17th 08:00 h for Eddy-C. Shorelines extracted from Global Self-consistent, Hierarchical, High-resolution Geography Database (GSHHG).
