The familiar axisymmetric zones and belts that characterize Jupiter’s weather system at lower latitudes give way to pervasive cyclonic activity at higher latitudes. Two-dimensional turbulence in combination with the Coriolis β-effect (that is, the large meridionally varying Coriolis force on the giant planets of the Solar System) produces alternating zonal flows. The zonal flows weaken with rising latitude so that a transition between equatorial jets and polar turbulence on Jupiter can occur… 
The number and location of Jupiter’s circumpolar cyclones explained by vorticity dynamics
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
Polygonal patterns of cyclones on Jupiter: Convective forcing and anticyclonic shielding
From its unique pole-to-pole orbit, the Juno spacecraft discovered cyclones arranged in polygonal patterns around the poles of Jupiter. In a related modeling study the stability of the pattern
The turbulent dynamics of Jupiter’s and Saturn’s weather layers: order out of chaos?
The weather layers of the gas giant planets, Jupiter and Saturn, comprise the shallow atmospheric layers that are influenced energetically by a combination of incoming solar radiation and localised
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
Oscillations and Stability of the Jupiter Polar Cyclones
Juno discovered the circumpolar cyclones polygons on Jupiter in 2017. Fundamental questions regarding Jovian cyclogenesis concern the formation mechanism and whether these cyclones are deep or
Deep model simulation of polar vortices in gas giant atmospheres
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
Deep convection–driven vortex formation on Jupiter and Saturn
Using three-dimensional simulations of turbulent convection in rotating spherical shells, it is proposed that a deep planetary dynamo acts to promote additional anticyclones, some as large as Jupiter’s Great Red Spot, in an overlying atmospheric layer.

The first close‐up images of Jupiter's polar regions: Results from the Juno mission JunoCam instrument
During Juno's first perijove encounter, the JunoCam instrument acquired the first images of Jupiter's polar regions at 50–70 km spatial scale at low emission angles. Poleward of 64–68° planetocentric
Jupiter’s magnetosphere and aurorae observed by the Juno spacecraft during its first polar orbits
Juno swoops around giant Jupiter Jupiter is the largest and most massive planet in the authors' solar system and Juno investigates Jupiter’s magnetosphere and the processes that drive aurorae on the giant planet.
Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
Findings on Jupiter's zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora are reported, including previously unseen emissions arising from Io and Europa in eclipse, and a giant volcanic plume over Io's north pole are described.
Jupiter’s interior and deep atmosphere: The initial pole-to-pole passes with the Juno spacecraft
Juno’s first close pass over Jupiter provides answers and fresh questions about the giant planet, including images of weather in the polar regions and measurements of the magnetic and gravitational fields and microwaves to peer below the visible surface.
