Panels A, C, and E: time-averaged diffusive and nondiffusive parts of the Reynolds stresses vs. vertical direction. The black and blue lines in panel A show the normalized vertical stresses at the equator and a latitude of 30° for set C24, respectively. In panel C the horizontal stresses are shown at a latitude of 30° for set C64. The blue and black lines in panel E show the meridional stresses for sets C06 and C64 at a latitude of 30°, respectively. The vertical lines denotes the z range used for volume averages. Solid, dotted, and dash-dotted lines show , , and , respectively. Panels B, D, and F: Volume averages over −2 ≤ zk₁ ≤ 2, of vs. Ω_⋆ at different latitudes as indicated by the legend.
