Repeated Cyclogenesis on Hot-Exoplanet Atmospheres with Deep Heating

We study the effect of deep heating (stellar irradiation deposited at the ~10^5 Pa level, as well as in the shallow region at the ~10^3 level) in hot-exoplanet atmospheres. Unlike with shallow heating (only), the atmosphere with deep heating exhibits a single equilibrium state, characterized by repeated generation of giant cyclonic vortices that move away westward from the point of emergence. The generation is accompanied by a burst of heightened turbulence activity, leading to the production of small-scale structures and large-scale mixing of temperature on a timescale of ~3 planetary rotations.
