Abstract: This paper shows how to obtain accurate and efficient trajectory calculations for spherical geodesic grids in Cartesian space. Determination of the departure points is essential to characteristic-based methods that trace ...

Abstract: A new dynamical core for numerical weather prediction (NWP) based on the spectral element method is presented. This paper represents a departure from previously published work on solving the atmospheric primitive equations ...

Abstract: nonhydrostatic, fully compressible spectral element (SE) model is evaluated in a series of two-dimensional idealized simulations. A dry formulation of the model is evaluated for a linear hydrostatic mountain-wave case, and ...

Abstract: he fundamental pathways for tropical cyclone (TC) intensification are explored by considering axisymmetric and asymmetric impulsive thermal perturbations to balanced, TC-like vortices using the dynamic cores of three ...
