Adiabatic Rearrangement of Hollow PV Towers

Diabatic heating from deep moist convection in the hurricane eyewall produces a towering annular structure of elevated potential vorticity (PV).This structure has been referred to as a hollow PV tower.The sign reversal of the radial gradient of PV satisfies the Charney-Stern necessary condition for combined barotropic-baroclinic instability.For thi
