Exploring planetary atmospheric processes from terrestrial worlds to giant planets.

The article summarizes the Royal Astronomical Society Specialist Discussion Meeting titled "Exploring Planetary Atmospheric Processes from Terrestrial Worlds to Giant Planets," held in November 2022. It covers diverse research on planetary atmospheres across the solar system, including terrestrial planets like Venus and Mars, gas giants such as Jupiter, and ice giants Uranus and Neptune, as well as comet 67P. Key topics include atmospheric structure and dynamics, ionosphere-magnetosphere coupling, dust storms, global electric circuits, and novel phenomena like ammonia-rich hail ("mushballs") on Jupiter. The meeting highlighted advances enabled by missions like JWST, Juno, and Rosetta, emphasizing ongoing challenges and the importance of interdisciplinary approaches to understanding planetary atmospheres and their interactions with space environments.
