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.Abstract:
The Cassini Imaging Science Subsystem acquired about 26,000 images of the Jupiter system as the spacecraft encountered the giant planet en route to Saturn. We report findings on Jupiter's zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora. We also describe previously unseen emissions arising from Io and Europa in eclipse, a giant volcanic plume over Io's north pole, disk-resolved images of the satellite Himalia, circumstantial evidence for a causal relation between the satellites Metis and Adrastea and the main jovian ring, and information on the nature of the ring particles.read more

Dynamical implications of Jupiter's tropospheric ammonia abundance
Adam P. Showman,Imke de Pater +1 more
TL;DR: In this article, the authors show that both the global depletion and its belt-zone variation can be explained by a simple model for the interaction of moist convection with Jupiter's cloud-layer circulation.

A strong decrease in Saturn's equatorial jet at cloud level
Agustín Sánchez-Lavega,Santiago Pérez-Hoyos,Jose Félix Rojas,Ricardo Hueso,Richard G. French +4 more
TL;DR: Saturn's winds show a large drop in the velocity of the equatorial jet of about 200 m s-1 from 1996 to 2002, and the other measured jets appear stable when compared to the Voyager wind profile of 1980–81.

TL;DR: In this paper, the authors present five epochs of WFC3 HST HST Jupiter observations taken between 2009-2016 and extract global zonal wind profiles for each epoch, finding that the largest uncertainties in the wind field are due to vortices or hot-spots.

Jupiter’s shrinking Great Red Spot and steady Oval BA: Velocity measurements with the ‘Advection Corrected Correlation Image Velocimetry’ automated cloud-tracking method
TL;DR: In this article, the authors show that between 1996 and 2006, the area circumscribed by the high-speed collar of the Great Red Spot (GRS) shrunk by 15% while the peak velocities within its collar remained constant.

Formation of Jets by Baroclinic Instability on Gas Planet Atmospheres
Yohai Kaspi,Glenn R. Flierl +1 more
TL;DR: In this paper, a nonlinear analytical model is developed that is truncated to one growing mode that exhibits a multiple jet meridional structure, driven by the nonlinear interaction between the eddies.

Capabilities and limitations of a current FORTRAN implementation of the T-matrix method for randomly oriented, rotationally symmetric scatterers
TL;DR: A detailed description of modern ¹-matrix FORTRAN codes which incorporate all recent developments, are publicly available on the World Wide Web, and are, apparently, the most efficient and powerful tool for accurately computing light scattering by randomly oriented rotationally symmetric particles is provided.

TL;DR: The cameras aboard Voyager 1 have provided a closeup view of the Jupiter system, revealing heretofore unknown characteristics and phenomena associated with the planet's atmosphere and the surfaces of its five major satellites.

The Vertical Profile of Radar Reflectivity of Convective Cells: A Strong Indicator of Storm Intensity and Lightning Probability?

TL;DR: In this article, reflectivity data from Doppler radars are used to construct vertical profiles of radar reflectivity (VPRR) of convective cells in mesoscale convective systems (MCSs) in three different environmental regimes.

New models of Jupiter's magnetic field constrained by the Io flux tube footprint
TL;DR: In this paper, a spherical harmonic model of the magnetic field of Jupiter was derived from in situ magnetic field measurements and remote observations of the position of the foot of the Io flux tube in Jupiter's ionosphere.

Origin of the main auroral oval in Jupiter's coupled magnetosphere–ionosphere system
TL;DR: In this article, a simple empirical model of the field and flow in the middle magnetosphere is used to estimate the field-aligned currents flowing into and out of the equatorial current sheet associated with the breakdown of corotation.
