The Juno mission observed that both poles of Jupiter have polar cyclones that are surrounded by a ring of circumpolar cyclones (CPCs). The north pole holds eight CPCs and the south pole possesses five, with both circumpolar rings positioned along latitude ~84° N/S. Here we explain the location, stability and number of the Jovian CPCs by establishing the primary forces that act on them, which develop because of vorticity gradients in the background of a cyclone. In the meridional direction, the… 
Moist convection drives an upscale energy transfer at Jovian high latitudes
Jupiter’s atmosphere is one of the most turbulent places in the solar system. Whereas observations of lightning and thunderstorms point to moist convection as a small-scale energy source for
Polar vortex crystals: Emergence and structure.
SignificanceVortex crystals, geometric arrays of like-signed vortices, are observed in natural systems with vastly different space and time scales: at the poles of Jupiter (∼10,000-km radius and
Dynamical Regimes of Polar Vortices on Terrestrial Planets with a Seasonal Cycle
Polar vortices are common planetary-scale flows that encircle the pole in the middle or high latitudes and are observed in most of the solar system’s planetary atmospheres. The polar vortices on


Clusters of cyclones encircling Jupiter’s poles
It is reported that visible and infrared images obtained from above each pole by the Juno spacecraft during its first five orbits reveal persistent polygonal patterns of large cyclones.
Some Aspects of Vortex Structure Related to Tropical Cyclone Motion
Abstract Some effect of tropical cyclone structure on the vortex motion are examined in a nondivergent, barotropic numerical model with no basic current. As suggested earlier by DeMaria, the initial
Modeling the stability of polygonal patterns of vortices at the poles of Jupiter as revealed by the Juno spacecraft
This work model the vortices using the shallow water equations, which describe a single layer of fluid that moves horizontally and has a free surface that moves up and down in response to fluid convergence and divergence, and finds that the stability of the pattern depends mostly on shielding—an anticyclonic ring around each cyclone, but also on the depth.
Cyclonic circulation of Saturn’s atmosphere due to tilted convection
Saturn displays cyclonic vortices at its poles and the general atmospheric circulation at other latitudes is dominated by embedded zonal jets that display cyclonic circulation. The abundance of
Weak Jets and Strong Cyclones: Shallow-Water Modeling of Giant Planet Polar Caps
AbstractGiant planet tropospheres lack a solid, frictional bottom boundary. The troposphere instead smoothly transitions to a denser fluid interior below. However, Saturn exhibits a hot, symmetric
A potential vorticity perspective on the motion of a mid‐latitude winter storm
The motion of mid‐latitude surface cyclones relative to the jet streams is of particular interest because of the commonly observed strong and rapid deepening they undergo when they cross the
First Estimate of Wind Fields in the Jupiter Polar Regions From JIRAM‐Juno Images
We present wind speeds at the ~ 1 bar level at both Jovian polar regions inferred from the 5‐μm infrared images acquired by the Jupiter InfraRed Auroral Mapper (JIRAM) instrument on the National
