Lightning activity on a tidally locked terrestrial exoplanet in storm-resolving simulations for a range of surface pressures
Denis E. Sergeev, James W. McDermott, Lottie Woods +3
Cloudy atmospheres produce electric discharges, including lightning. Lightning, in turn, provides sufficient energy to break down air molecules into reactive species and thereby af…
Simulations of idealised 3D atmospheric flows on terrestrial planets using LFRic-Atmosphere
Denis E. Sergeev, Nathan J. Mayne, Thomas Bendall +13
We demonstrate that LFRic-Atmosphere, a model built using the Met Office's GungHo dynamical core, is able to reproduce idealised large-scale atmospheric circulation patterns specif…
3D climate simulations of the Archean find that methane has a strong cooling effect at high concentrations
Jake K. Eager-Nash, Nathan J. Mayne, Arwen E. Nicholson +11
Methane is thought to have been an important greenhouse gas during the Archean, although its potential warming has been found to be limited at high concentrations due to its high s…
A modern-day Mars climate in the Met Office Unified Model: dry simulations
Danny McCulloch, Denis E. Sergeev, Nathan Mayne +5
We present results from the Met Office Unified Model (UM), a world-leading climate and weather model, adapted to simulate a dry Martian climate. We detail the adaptation of the bas…
Bistability of the atmospheric circulation on TRAPPIST-1e
Denis E. Sergeev, Neil T. Lewis, F. Hugo Lambert +4
Using a 3D general circulation model, we demonstrate that a confirmed rocky exoplanet and a primary observational target, TRAPPIST-1e presents an interesting case of climate bistab…
Longitudinally asymmetric stratospheric oscillation on a tidally locked exoplanet
Maureen Cohen, Massimo A. Bollasina, Paul I. Palmer +4
Using a three-dimensional general circulation model, we show that the atmospheric dynamics on a tidally locked Earth-like exoplanet, simulated with the planetary and orbital parame…
The TRAPPIST-1 Habitable Atmosphere Intercomparison (THAI). Part III: Simulated Observables -- The return of the spectrum
Thomas J. Fauchez, Geronimo L. Villanueva, Denis E. Sergeev +11
The TRAPPIST-1 Habitable Atmosphere Intercomparison (THAI) is a community project that aims to quantify how dfferences in general circulation models (GCMs) could impact the climate…
The TRAPPIST-1 Habitable Atmosphere Intercomparison (THAI). Part II: Moist Cases -- The Two Waterworlds
Denis E. Sergeev, Thomas J. Fauchez, Martin Turbet +11
To identify promising exoplanets for atmospheric characterization and to make the best use of observational data, a thorough understanding of their atmospheres is needed. 3D genera…
The TRAPPIST-1 Habitable Atmosphere Intercomparison (THAI). Part I: Dry Cases -- The fellowship of the GCMs
Martin Turbet, Thomas J. Fauchez, Denis E. Sergeev +12
With the commissioning of powerful, new-generation telescopes such as the James Webb Space Telescope (JWST) and the ground-based Extremely Large Telescopes, the first characterizat…
TRAPPIST Habitable Atmosphere Intercomparison (THAI) workshop report
Thomas J. Fauchez, Martin Turbet, Denis E. Sergeev +31
The era of atmospheric characterization of terrestrial exoplanets is just around the corner. Modeling prior to observations is crucial in order to predict the observational challen…
Mineral dust increases the habitability of terrestrial planets but confounds biomarker detection
Ian A. Boutle, Manoj Joshi, F. Hugo Lambert +5
Identification of habitable planets beyond our solar system is a key goal of current and future space missions. Yet habitability depends not only on the stellar irradiance, but equ…
Implications of different stellar spectra for the climate of tidally-locked Earth-like exoplanets
Jake K. Eager, David J. Reichelt, Nathan J. Mayne +7
The majority of potentially habitable exoplanets detected orbit stars cooler than the Sun, and therefore are irradiated by a stellar spectrum peaking at longer wavelengths than tha…
Atmospheric convection plays a key role in the climate of tidally-locked terrestrial exoplanets: insights from high-resolution simulations
Denis E. Sergeev, F. Hugo Lambert, Nathan J. Mayne +3
Using a 3D general circulation model (GCM), we investigate the sensitivity of the climate of tidally-locked Earth-like exoplanets, Trappist-1e and Proxima Centauri b, to the choice…
TRAPPIST-1 Habitable Atmosphere Intercomparison (THAI). Motivations and protocol version 1.0
Thomas J. Fauchez, Martin Turbet, Eric T. Wolf +10
Upcoming telescopes such as the James Webb Space Telescope (JWST), or the Extremely Large Telescope (ELTs), may soon be able to characterize, through transmission, emission or refl…
Ozone chemistry on tidally locked M dwarf planets
Jack S. Yates, Paul I. Palmer, James Manners +4
We use the Met Office Unified Model to explore the potential of a tidally locked M dwarf planet, nominally Proxima Centauri b irradiated by a quiescent version of its host star, to…
The Limits of the Primitive Equations of Dynamics for Warm, Slowly Rotating Small Neptunes and Super Earths
N. J. Mayne, B. Drummond, F. Debras +5
We present significant differences in the simulated atmospheric flow for warm, tidally-locked small Neptunes and super Earths (based on a nominal GJ 1214b) when solving the simplif…
