  The polar regions of Jupiter host a myriad of dynamically interesting
phenomena including vortex configurations, folded-filamentary regions (FFRs),
and chaotic flows. Juno observations have provided unprecedented views of the
high latitudes, allowing for more constraints to be placed upon the troposphere
and the overall atmospheric energy cycle. Moist convective events are believed
to be the primary drivers of energetic storm behavior as observed on the
planet. Here, we introduce a novel single layer shallow water model to
investigate the effects of polar moist convective events at high resolution,
the presence of dynamical instabilities over long timescales, and the emergence
of FFRs at high latitudes. We use a flexible, highly parallelizable,
finite-difference hydrodynamic code to explore the parameter space set up by
previous models. We study the long term effects of deformation length (Ld),
injected pulse size, and injected geopotential. We find that models with Ld
beyond 1500 km (planetary Burger number, Bu$=4.4\times10^{-4}$) tend to
homogenize their potential vorticity (PV) in the form of dominant stable polar
cyclones, while lower Ld cases tend to show less stability with regards to
Arnol'd-type flows. We also find that large turbulent forcing scales
consistently lead to the formation of high latitude FFRs. Our findings support
the idea that moist convection, occurring at high latitudes, may be sufficient
to produce the dynamical variety seen at the Jovian poles. Additionally,
derived values of localized horizontal shear and Ld may constrain FFR formation
and evolution.
