High potential vorticity
WebJan 1, 2000 · On shallow isopycnals, high potential vorticity is found in the tropics, subpolar gyre, and along the eastern boundary of the subtropical gyre, all associated with Ekman upwelling. Low potential ... WebPotential vorticity (PV) is the atmosphere's best equivalent to a dye in water, and therefore can be used to analyse and track shortwaves aloft (and the frontal disturbances associated with it). It can also be used to explain …
