Acceleration of daily land temperature extremes and correlations with surface energy fluxes
(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
(Elsevier, 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
(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 ... -
Temperature-reducing shocks in optically thin radiative MHD - Analytical and numerical results
(AIP Publishing, 15 July 2024)Shocks are often invoked as heating mechanisms in astrophysical systems, with both adiabatic compression and dissipative heating that leading to the increase in temperature. While shocks are reasonably well understood for ... -
Effects of stratification on overshooting and waves atop the convective core of M⊙ main-sequence stars
(Oxford University Press / Royal Astronomical Society, 9 July 2024)As a massive star evolves along the main sequence, its core contracts, leaving behind a stable stratification in helium. We simulate two-dimensional convection in the core at three different stages of evolution of a [Formula ...
