A new look at the problem of tropical cyclones in vertical shear flow: Vortex resiliency

Montgomery et al present a new paradigm for the resiliency of tropical cyclone (TC) vortices in vertical shear flow. It is argued that the diabatically driven secondary circulation of the TC is not directly responsible for maintaining the vertical alignment of the vortex. Rather, an inviscid damping...

Summary:Montgomery et al present a new paradigm for the resiliency of tropical cyclone (TC) vortices in vertical shear flow. It is argued that the diabatically driven secondary circulation of the TC is not directly responsible for maintaining the vertical alignment of the vortex. Rather, an inviscid damping mechanism intrinsic to the dry adiabatic dynamics of the TC vortex suppresses departures from the upright state.
