Isentropic zonal average formalism and the near-surface circulation
Hoskins (1991) proposed dividing the atmosphere into 3 regions: Overworld, Middleworld and Underworld, using potential temperature θ and potential vorticity (PV) as reference (Fig. 1). In the Underworld (θ < 300 K), isentropes intercept the Earth’s surface and a direct isentropic zonal aver...
