Cloudy atmospheres produce electric discharges, including lightning. Lightning, in turn, provides sufficient energy to break down air molecules into reactive species and thereby affects the atmospheric composition.

Biogenic Sulfur Gases As Biosignatures On Temperate Sub-Neptune Waterworlds
Theoretical predictions and observational data indicate a class of sub-Neptune exoplanets may have water-rich interiors covered by hydrogen-dominated atmospheres. Provided suitable climate conditions, such planets could host surface liquid oceans.

Cloud Behaviour On Tidally Locked Rocky Planets From Global High-resolution Modeling
Determining the behaviour of convection and clouds is one of the biggest challenges in our understanding of exoplanetary climates.

The Effect of Substellar Continent Size on Ocean Dynamics of Proxima Centauri b
The potential habitability of tidally locked planets orbiting M-dwarf stars has been widely investigated in recent work, typically with a non-dynamic ocean and without continents. On Earth, ocean dynamics are […]
