Tropical - Midlatitude Interactions and Significant Summertime Weather in the Australian Region

Abstract
In the Australian region during summer, Rossby waves preferentially break anticyclonically around the latitudes of eastern Australia, and in the process, cyclonic potential vorticity is transported equatorward and anticyclonic potential vorticity is transported poleward. Much of the significant weather in the region can be attributed to this kind of stirring of the potential vorticity field and the potential vorticity anomalies so produced. This talk will examine the main ingredients for such processes in the region.
