Earth-like planets in the circumstellar habitable zone (HZ) may have dramatically different climate outcomes depending on their spin-orbit parameters, altering their habitability for life as we know it.

A Combined 3D Model Applied To Cloudy Warm Saturn Type Exoplanets Around M-dwarfs
Warm Saturn type exoplanets orbiting M-dwarfs are particularly suitable for in-depth cloud characterisation through transmission spectroscopy due to their favourable stellar to planetary radius contrast.

Three-Dimensional Venus Cloud Structure Simulated by a General Circulation Model
The clouds have a great impact on Venus’s energy budget and climate evolution, but its three-dimensional structure is still not well understood. Here we incorporate a simple Venus cloud physics […]

ExoCubed: A Riemann-Solver Based Cubed-Sphere Dynamic Core For Planetary Atmospheres
The computational fluid dynamics on a sphere is relevant to global simulations of geophysical fluid dynamics. Using the conventional spherical-polar (or lat-lon) grid results in a singularity at the poles, […]

3D Simulations Of TRAPPIST-1e With Varying CO2, CH4 And Haze Profiles
Using a 3D General Circulation Model, the Unified Model, we present results from simulations of a tidally-locked TRAPPIST-1e with varying carbon dioxide CO2 and methane CH4 gas concentrations, and their […]

Circumpolar Ocean Stability On Mars 3 Billion Years Ago
What was the nature of the Late Hesperian climate? Warm and wet or cold and dry? Formulated this way the question leads to an apparent paradox since both options seem […]

Interior Dynamics Of Super-Earth 55 Cancri e
The ultra-short-period super-Earth 55 Cancri e has a measured radius of 1.8 Earth radii. Previous thermal phase curve observations suggest a strong temperature contrast between the dayside and nightside of […]

Equatorial Waves And Superrotation In The Stratosphere Of A Titan General Circulation Model
We investigate the characteristics of equatorial waves associated with the maintenance of superrotation in the stratosphere of a Titan general circulation model.

Day-night Transport Induced Chemistry And Clouds On WASP-39b I: Gas-phase Composition
JWST has recently detected the first robust photochemical product on an exoplanet: sulfur dioxide (SO2) on WASP-39b (Rustamkulov et al. 2023; Alderson et al. 2023; Tsai et al. 2023b).
