    • State‐Dependence of the Equilibrium Climate Sensitivity in a Clear‐Sky GCM 

      Henry, M; Vallis, GK; Lutsko, NJ; et al. (Wiley / American Geophysical Union (AGU), 29 November 2023)
      The climate sensitivity peaks around 310 K in a wide variety of climate models, ranging from idealized single column models to fully comprehensive climate models. Here, we increase CO2 using a clear-sky three-dimensional ...

    • Reduction in the Tropical High Cloud Fraction in Response to an Indirect Weakening of the Hadley Cell 

      Natchiar, SRM; Webb, MJ; Lambert, FH; et al. (Wiley / American Geophysical Union (AGU), 28 May 2024)
      Tropical high cloud cover decreases with surface warming in most general circulation models. This reduction, according to the “stability-iris” hypothesis, is thermodynamically controlled and linked to a decrease in the ...

    • Acceleration of daily land temperature extremes and correlations with surface energy fluxes 

      Huntingford, C; Cox, PM; Ritchie, PDL; et al. (Nature Research, 4 April 2024)
      Assessment of climate reanalysis data for land (ECMWF Re-Analysis v5; ERA5-Land) covering the last seven decades reveals regions where extreme daily mean temperatures are rising faster than the average rate of temperature ...

    • Arbitrary sensitive transitions in recurrent neural networks 

      Fadera, M; Ashwin, P (Elsevier, 11 September 2024)
      An Excitable Network Attractor (ENA) is a forward-invariant set in phase space that can be used to explain input-driven behaviour of Recurrent Neural Networks (RNNs) trained on tasks involving switching between a discrete ...

    • Numerical validation of scaling laws for stratified turbulence 

      Garaud, P; Chini, GP; Cope, L; et al. (Cambridge University Press, 25 July 2024)
      Recent theoretical progress using multiscale asymptotic analysis has revealed various possible regimes of stratified turbulence. Notably, buoyancy transport can either be dominated by advection or diffusion, depending on ...
