On internal wave whispering gallery modes in channels and critical-slope wave attractors Open
Internal waves are an important feature of stratified fluids, both in oceanic and lake basins and in other settings. Many works have been published on the generic feature of internal wave trapping onto planar wave attractors and super-attr…

Fire weather indices tailored to regional patterns outperform global models Open
Fire weather indices (FWIs) are widely used to assess wildfire risk, but are typically designed for specific regions and not adapted globally. Here, we present a systematic effort to generate country-specific FWIs that capture regional fir…

A novel non-specular mechanism for chaotic ray scattering of internal waves in 3D anisotropic stadiums Open
Fluids, subject to symmetry breaking by stratification support propagation of anisotropic internal waves - IWs. In the vertical plane, rays representing energy paths obey a non-specular reflection law, as their inclination is solely dictat…
