Discussion

Set a barotropic geostrophic state from sea-surface height.

ssh is a function handle evaluated on the horizontal grid. The transform converts height to geostrophic streamfunction using \(\psi=g\eta/f\). Set shouldRemoveMeanPressure=true to remove the horizontal mean first; the default is false.

wvt.setSSH(@(x,y)0.1*cos(2*pi*x/wvt.Lx));
