TLDR
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

The 2009–2010 fade of Jupiter’s South Equatorial Belt: Vertical cloud structure models and zonal winds from visible imaging
Santiago Pérez-Hoyos,J. F. Sanz-Requena,N. Barrado-Izagirre,Jose Félix Rojas,Agustín Sánchez-Lavega +4 more
TL;DR: In this paper, the authors focus on the near ultraviolet to near infrared reflected sunlight (255-953-nm) to address two issues: the nature of the change in the upper clouds and hazes and whether or not this reflectivity change is accompanied by a change in winds at the upper cloud level.

Jupiter’s Unearthly Jets: A New Turbulent Model Exhibiting Statistical Steadiness without Large-Scale Dissipation*
TL;DR: In this article, the Dowling-Ingersoll (DI) 1½-layer scenario and its supporting observational evidence were taken seriously, pointing toward deep, massive, zonally symmetric zonal jets in the underlying dry-convective layer.

Power spectral analysis of Jupiter's clouds and kinetic energy from Cassini
David S. Choi,Adam P. Showman +1 more
TL;DR: In this article, the authors present evidence for an inverse energy cascade within Jupiter's atmosphere through a calculation of the power spectrum of its kinetic energy and its cloud patterns using Cassini observations, with power-law slopes near −5/3 and −3 at low and high wavenumbers, respectively.

Anelastic spherical dynamos with radially variable electrical conductivity
Wieland Dietrich,Chris A. Jones +1 more
TL;DR: In this article, a series of numerical simulations of the dynamo process operating inside gas giant planets has been performed using an anelastic, fully nonlinear, three-dimensional, benchmarked MHD code to evolve the flow, entropy and magnetic field.

On the long-term variability of Jupiter’s winds and brightness as observed from Hubble
TL;DR: In this article, the authors combined Wide Field Planetary Camera 2 imaging data of Jupiter with wind profiles from Voyager and Cassini data to study long-term variability in Jupiter's winds and cloud brightness and found that the most significant periods were found nearly symmetrically about the equator at 0 deg., 10-12 deg. N, and 14-18 deg. S planetographic latitude.

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.

The Vertical Profile of Radar Reflectivity of Convective Cells: A Strong Indicator of Storm Intensity and Lightning Probability?
Edward J. Zipser,Kurt R. Lutz +1 more
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.
