Annual mean variations in the upper main pycnocline depth forced by variations in the wind stress (solid line) and the in situ halocline depth (dashed line) at station K2. The main pycnocline depth is indicated by the pressure level of the potential density of 26.8 σθ and the halocline depth is the pressure level of the isohaline (33.8) estimated from the ship-board CTD and Argo data by Wakita et al. (2017)
