Observations of forced flow over the highly asymmetric topography of the Darling Scarp, Western Australia, are presented. These are typified by shallow surface gradient winds of 10-20 m s-1 with an inherent critical level aloft and a stable layer produced through nocturnal radiational cooling. The observations highlight a topographically induced hydraulic jump, lee waves or vertically propagating hydrostatic waves depending on the upwind stability and wind profile. The vertically propagating waves and hydraulic jump are observed to produce accelerated flow down the escarpment.
