Effects of environmental flow on the internal dynamics of tropical cyclones, The
This dissertation focuses on two projects that examine the interaction between the internal dynamics of tropical cyclones and the large-scale environmental flow using a hierarchy of numerical model simulations. Diabatic heating from deep moist convection in the hurricane eyewall produces a towering annular structure of elevated potential vorticity (PV) called a hollow PV tower. For the first project, the three-dimensional rearrangement of hurricane-like hollow PV towers is examined in an idealized framework. For the adiabatic PV tower in the absence of environmental flow, barotropic instability ...
