The suppressed monsoon over Darwin is due to a deep low over central Australia (Fig. 11F1.11). Such deep lows are referred to colloquially as ?landfoons?. The MSLP/vorticity chart shows that the monsoon trough is well to the south of Darwin, together with the associated convergence. The flow is southwesterly rather than west to northwesterly flow associated with an active monsoon.
