(a) Salinity, (b) stream function of ageostrophic current, and (c) vertical velocity (positive in upward) as a function of depth. Solid isolines indicate σ_θ, whose intervals are 0.1 and 0.5 kg m⁻³ for thin and thick lines, respectively. Intervals of dotted isolines in (b) and (c) are 0.1 m² s⁻¹ and 10 m d⁻¹, respectively. Inversed triangles and red arrows are the same as those in Fig. 5.
