Abstract
A high-resolution (3-km horizontal grid spacing) near-cloud-resolving numerical simulation of Hurricane Diana (1984) reveals areas of deep cumulonimbus convection possessing intense vertical vorticity in their cores, and demonstrates that these vortical hot towers are the most important influence in the formation of Diana. Specifically, the towers influence the formation of the tropical storm via preconditioning of the local environment via diabatic production of multiple small-scale lower-tropospheric cyclonic potential vorticity (PV) anomalies, and through multiple mergers and axisymmetrization of these low-level PV anomalies.
