Now on arXiv: novel method of simulating #convection on #exoplanets: a global 3D climate model with a stretched mesh. Tidally locked exoplanets are an excellent use case for this! We used the new Met Office model, #LFRic-Atmosphere. Paper in review: arxiv.org/abs/2402.19277

Key takeaways:
* at CH4/CO2=0.1 -> thin haze -> changes in water vapour and clouds -> global warming of ~10.6 K
* at CH4/CO2>0.1 -> thick haze -> reduction in the amount of SW radiation reaching the deeper atmosphere -> global cooling
* 3D models are key to capture the warming/cooling effect of haze

We are currently working on adapting LFRic for hot gaseous exoplanets, so expect even more exciting results to come!

LFRic also reproduces the THAI scenarios within the spread of the existing models across a range of key climatic variables
October 10, 2023 at 11:38 AM
Importantly, LFRic has excellent conservation properties in terms of total mass, angular momentum, and kinetic energy
