Hurricane‐Like Vortices in Conditionally Unstable Moist Convection

Abstract This study investigates the emergence of hurricane‐like vortices in idealized simulations rotating moist convection. A Boussinesq atmosphere with simplified thermodynamics for phase transitions is forced by prescribing temperature and humidity at upper lower boundaries. The governing equations are solved numerically using a variable‐density incompressible Navier‐Stokes solver adaptive mesh refinement to explore behavior convection under broad range conditions. In absence rotation, aggregates into active patches separated large unsaturated regions. Rotation modulates this statistical equilibrium state so that self‐aggregated organizes vortices. warm saturated air converges center vortices, latent heat released through upwelling, forms core structure. These share characteristics similar tropical cyclones earth's atmosphere. occur conditionally unstable conditions where potential energy given boundaries enough, corresponding moderate rate rotation. regime shares many indicating formation intense meso‐scale general characteristic model used here does not include any interactions radiation, wind‐evaporation feedback, or cloud microphysics, that, while these processes may be relevant cyclogenesis Earth atmosphere, they its primary cause. Instead, our results confirm maintenance involve combination atmospheric dynamics presence rotation transitions.
