a) Vertical components of first temperature (solid line) and salinity (dashed) EOFs; salinity EOF has been multiplied by 5.
b) Vertical gradients of mean temperature and salinity profiles; salinity gradient has been multiplied by 5.
c) Vertical displacement EOFs, calculated by dividing the principal EOFs by their respective vertical gradients.
d) First three vertical displacement baroclinic modes.
