Neptune receives only 1/900th of the earth's solar energy, but has wind speeds of nearly 600 meters per second. How the near-supersonic winds can be maintained has been a puzzle. A plausible mechanism, based on principles of angular momentum and energy conservation in conjunction with deep convection, leads to a regime of uniform angular momentum at low latitudes. In this model, the rapid retrograde winds observed are a manifestation of deep convection, and the high efficiency of the planet's… 
Interior Structure of Neptune: Comparison with Uranus
TLDR
Comparison of shock data with inferred pressure-density profiles for both Uranus and Neptune shows substantial similarity through most of the mass of both planets.
Atmospheric confinement of jet streams on Uranus and Neptune
TLDR
It is reported that on Uranus and Neptune the depth of the atmospheric dynamics can be revealed by the planets’ respective gravity fields, and that the dynamics are confined to a thin weather layer no more than about 1,000 kilometres deep on both planets.
Radiation-Hydrodynamics of Hot Jupiter Atmospheres
Radiative transfer in planetary atmospheres is usually treated in the static limit, i.e., neglecting atmospheric motions. We argue that hot Jupiter atmospheres, with possibly fast (sonic) wind

Neptune's Wind Speeds Obtained by Tracking Clouds in Voyager Images
TLDR
Images of Neptune obtained by the narrow-angle camera of the Voyager 2 spacecraft reveal large-scale cloud features that persist for several months or longer, and wind speeds computed with respect to this radio period are roughly the same for all the planets ranging from Venus to Neptune.
Atmospheric Dynamics of the Outer Planets
Despite major differences in the solar and internal energy inputs, the atmospheres of the four Jovian planets all exhibit latitudinal banding and high-speed jet streams. Neptune and Saturn are the
Voyager 2 at Neptune: Imaging Science Results
Voyager 2 images of Neptune reveal a windy planet characterized by bright clouds of methane ice suspended in an exceptionally clear atmosphere above a lower deck of hydrogen sulfide or ammonia ices.
Voyager Planetary Radio Astronomy at Neptune
TLDR
This experiment detected the foreshock of Neptune's magnetosphere and the impacts of dust at the times of ring-plane crossings and also near the time of closest approach, and found no evidence for Neptunian electrostatic discharges.
Nylon Production: An Unknown Source of Atmospheric Nitrous Oxide
TLDR
Characterization of the reaction N2O stoichiometry and its isotopic composition with a simulated industrial adipic acid synthesis indicates that because of high rates of global adipic Acid production, this N2o may account for ∼10 percent of the increase observed for atmospheric N2 O.
On the irreversible production of entropy
The importance of irreversible entropy production is emphasized. The first and second laws of thermodynamics are both expressed by equalities by giving due recognition to the irreversible production
