Barotropic results of modelling the Koorin Experiment are presented. The effects of the inertial oscillation on the acceleration of the low-level wind are unable to account for the concentrated low-level jets frequently seen before the sea-breeze arrival when the wind is from south of east. Assuming that the effects of baroclinity are negligible, one is left to conclude that, despite the small scope of the land at Daly Waters, the katabatic effect is probably responsible for these jets. Sea-breezes almost always occur in the dry season, and the model certainly predicts this; but there are two classes of sea-breezes at Daly Waters, determined by the shape of the adjacent coast (280 km distant). The first type occurs when the preexisting wind is from north of east, which the model simulates rather well, except that the modelled sea-breeze is too strong. The second type occurs when the preexisting wind is from south of east. In this case the model fails to adequately predict the strong pre sea-breeze development of the low-level jet, and thus fails to simulate what may be regarded as a somewhat unexpected phenomenon, which was observed on 12 nights: the apparent lifting of the low-level jet by the relatively weak sea-breeze forcing its way beneath the jet.
