""Deep model simulation of polar vortices in gas giant atmospheres"", by Garcia, Chambers & Watts. <LINK> We've been working on convection in neutron star oceans (rapid rotation, pattern formation etc).

Quite an excursion from my normal research track! But it's been really fun. And a fluid is a fluid is a fluid..... @ThomsLrn Thanks! Equatorially asymmetric waves develop from the onset in the selected regime (see also our 2019 PRF paper) which may explain the lack of symmetry in our models. Opposite symmetry is also possible, as equations are invariant with respect to reflections in equatorial plane. Plus the figures are gorgeous. <LINK>",https://arxiv.org/abs/2006.14817,"The Cassini and Juno probes have revealed large coherent cyclonic vortices in the polar regions of Saturn and Jupiter, a dramatic contrast from the east-west banded jet structure seen at lower latitudes. Debate has centered on whether the jets are shallow, or extend to greater depths in the planetary envelope. Recent experiments and observations have demonstrated the relevance of deep convection models to a successful explanation of jet structure and cyclonic coherent vortices away from the polar regions have been simulated recently including an additional stratified shallow layer. Here we present new convective models able to produce long-lived polar vortices. Using simulation parameters relevant for giant planet atmospheres we find flow regimes that are in agreement with geostrophic turbulence (GT) theory in rotating convection for the formation of large scale coherent structures via an upscale energy transfer fully three-dimensional. Our simulations generate polar characteristics qualitatively similar to those seen by Juno and Cassini: they match the structure of cyclonic vortices seen on Jupiter; or can account for the existence of a strong polar vortex extending downwards to lower latitudes with a marked spiral morphology and the hexagonal pattern seen on Saturn. Our findings indicate that these vortices can be generated deep in the planetary interior. A transition differentiating these two polar flows regimes is described, interpreted in terms of different force balances and compared with previous shallow atmospheric models which characterised polar vortex dynamics in giant planets. In addition, the heat transport properties are investigated confirming recent scaling laws obtained in the context of reduced models of GT.
