takes no account of horizontal gradients and associated geostrophic shear, as well as advection of WDW and Ekman transport in the IOBL, cannot expect to fully describe changes over three weeks. However, from an heuristic viewpoint, the results for the MaudNESS simulation suggest how some of the otherwise puzzling features encountered in the low stability regimes near Maud Rise come about.
