Abstract	Air flow over regions of complex terrain is of both local (e.g. wind speed up precipitation enhancement) and large-scale (e.g. gravity-wave drag) importance. Although it is widely recognised that many of the flow processes are unsteady, theories and models generally assume a steady state. We will use unique datasets gathered by our group during the course of several field experiments in regions of mesoscale complex terrain. New diagnostic techniques will be developed for the interpretation of unsteady processes such as eddy shedding, rotor formation and transient gravity wave activity. Linear and nonlinear numerical models will be compared with the observations, leading to interpretation of flow regimes and improvement of models.
