Although lightning has been seen on other planets, including Jupiter, polar lightning has been known only on Earth. Optical observations from the New Horizons spacecraft have identified lightning at high latitudes above Jupiter up to 80°N and 74°S. Lightning rates and optical powers were similar at each pole, and the mean optical flux is comparable to that at nonpolar latitudes, which is consistent with the notion that internal heat is the main driver of convection. Both near-infrared and…

Jupiter Cloud Composition, Stratification, Convection, and Wave Motion: A View from New Horizons
Several observations of Jupiter's atmosphere made by instruments on the New Horizons spacecraft have implications for the stability and dynamics of Jupiter's weather layer. Mesoscale waves, first
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
Equatorial winds on Saturn and the stratospheric oscillation
The zonal jets on the giant planets have been thought to be stable in time. A decline in the velocity of Saturn’s equatorial jet has been identified, on the basis of a comparison of cloud-tracking
Prevalent lightning sferics at 600 megahertz near Jupiter’s poles
Observations of broadband emission from lightning on Jupiter at 600 megahertz show a lightning discharge mechanism similar to that of terrestrial lightning and indicate increased moist convection near Jupiter’s poles.
Three-dimensional modeling of lightning-induced electromagnetic pulses on Venus, Jupiter and Saturn
While lightning activity in Venus is still controversial, its existence in Jupiter and Saturn was first detected by the Voyager missions and later on confirmed by Cassini and New Horizons optical
How Well Do We Understand the Belt/Zone Circulation of Giant Planet Atmospheres?
This review is an attempt to reconcile the observed properties of belts and zones with (i) the meridional overturning inferred from the convergence of eddy angular momentum into the eastward zonal jets at the cloud level on Jupiter and Saturn and the prevalence of moist convective activity in belts; and (ii) the opposingMeridional motions inferredfrom the upper tropospheric temperature structure, which implies decay and dissipation of the zonal Jets with altitude above the clouds.
Storm clouds on Saturn: Lightning-induced chemistry and associated materials consistent with Cassini/VIMS spectra
Abstract Thunderstorm activity on Saturn is associated with optically detectable clouds that are atypically dark throughout the near-infrared. As observed by Cassini/VIMS, these clouds are ~20% less
Atmospheric Electricity at Saturn
The Cassini mission provides a great opportunity to enlarge our knowledge of atmospheric electricity at the gas giant Saturn. Following Voyager studies, the RPWS (Radio and Plasma Wave Science)
Jupiter’s Atmospheric Variability from Long-term Ground-based Observations at 5 μm
Jupiter's banded structure undergoes strong temporal variations, changing the visible and infrared appearance of the belts and zones in a complex and turbulent way due to physical processes that are
Cassini Exploration of the Planet Saturn: A Comprehensive Review
Before Cassini, scientists viewed Saturn’s unique features only from Earth and from three spacecraft flying by. During more than a decade orbiting the gas giant, Cassini studied the planet from its

Spatial distribution of visible lightning on Jupiter
SPACECRAFT observations have provided evidence for the existence of lightning on Venus1–3, Jupiter4,5, Saturn6,7 and Uranus8. Little is known, however, about the global distribution of lightning on
Galileo Images of Lightning on Jupiter
In October and November of 1997 the Galileo Solid State Imager (SSI) detected lightning from 26 storms on the night side of Jupiter. More than half the surface area of the planet was surveyed. The
Observation of moist convection in Jupiter's atmosphere
It is concluded that moist convection—similar to large clusters of thunderstorm cells on the Earth—is a dominant factor in converting heat flow into kinetic energy in the jovian atmosphere.
