Hovmöller zonal–time diagrams at the sea surface of the equator (left panels) and depth–time diagrams at 70°E of the equator (right panels) from OGCM OFES (a, b) and “Year 20” of our climatological model experiments (c–f), respectively. Color shading in the panels (a–d) shows the output of zonal component of velocity based on OGCM (a, b) and LOM (c, d) with a unit of m/s. Color shading in the panels (e–f) shows simulated geopotential anomaly with a unit of m2/s2. Panels (a, c) include the zonal component of wind stress (solid and dotted contours for positive and negative values, respectively, with an interval of 0.1 N/m2) from OGCM and LOM, respectively. Panels (b, d) include the meridional component of velocity based on OGCM and LOM (solid- and dotted-line contours for positive and negative values, respectively, with an interval of 0.02 m/s). Panel (f) includes the vertical component of simulated velocity (solid and dotted contours for positive and negative values, respectively, with an interval of 4 × 10−6 m/s). Solid blue lines in the panels (c, e) indicate the theoretical phase speeds of both Kelvin waves and equatorial long Rossby waves in the second baroclinic mode
