    Catastrophic and violent tornadoes: a detailed review of physical-mathematical models by Sergey A. Arsen’yev, Lev V. Eppelbaum

    Published 2024-11-01
    “…Second, the wind in the upper atmosphere and nonlinearity amplifies the resulting gravity nonlinear wave, which propagates at the speed of the initial tidal wave. When a gravity wave reaches a thunderstorm supercell that has already formed inside the atmospheric front, it is captured by the supercell because upward air movements destroy its inversion. …”

    Error Analysis of an Implicit Spectral Scheme Applied to the Schrödinger-Benjamin-Ono System by Juan Carlos Muñoz Grajales

    Published 2016-01-01
    “…We develop error estimates of the semidiscrete and fully discrete formulations of a Fourier-Galerkin numerical scheme to approximate solutions of a coupled nonlinear Schrödinger-Benjamin-Ono system that describes the motion of two fluids with different densities under capillary-gravity waves in a deep water regime. The accuracy of the numerical solver is checked using some exact travelling wave solutions of the system.…”

    Published 2025-01-01
    “…A single number is usually employed to classify trans-criticality namely the local depth Froude number which is the ratio between the local current speed and the local celerity of long gravity waves analogous to the light celerity. When the former reaches one, water waves are no more able to propagate upstream: the hydraulic black hole is a river of no return for them. …”
