Investigating Inherent Numerical Stabilization for the Moist, Compressible, Non‐Hydrostatic Euler Equations on Collocated Grids
Autor: Matthew R. Norman, Christopher Eldred, Muralikrishnan Gopalakrishnan Meena
Publikováno v: Journal of Advances in Modeling Earth Systems, Vol 15, Iss 10, Pp n/a-n/a (2023)
Abstract This study investigates inherent numerical dissipation due to upwind fluxes and reconstruction strategies for collocated Finite‐Volume integration of the Euler equations. Idealized supercell simulations are used without any explicit dissip

An Energy Consistent Discretization of the Nonhydrostatic Equations in Primitive Variables
Autor: Mark A. Taylor, Oksana Guba, Andrew Steyer, Paul A. Ullrich, David M. Hall, Christopher Eldred
Publikováno v: Journal of Advances in Modeling Earth Systems, Vol 12, Iss 1, Pp n/a-n/a (2020)
Abstract We derive a formulation of the nonhydrostatic equations in spherical geometry with a Lorenz staggered vertical discretization. The combination conserves a discrete energy in exact time integration when coupled with a mimetic horizontal discr

Unprecedented cloud resolution in a GPU-enabled full-physics atmospheric climate simulation on OLCF’s summit supercomputer
Autor: Xingqiu Yuan, Walter M. Hannah, L. R. Leung, Christopher Eldred, Isaac Lyngaas, Mark A. Taylor, B. R. Hillman, Sarat Sreepathi, David A Bader, Matthew R. Norman, Kyle G. Pressel, J. Lee, C. R. Jones
Publikováno v: The International Journal of High Performance Computing Applications. 36:93-105
Clouds represent a key uncertainty in future climate projection. While explicit cloud resolution remains beyond our computational grasp for global climate, we can incorporate important cloud effects through a computational middle ground called the Mu

Fourier Analyses of High-Order Continuous and Discontinuous Galerkin Methods
Autor: Daniel Y. Le Roux, Mark A. Taylor, Christopher Eldred
Publikováno v: SIAM Journal on Numerical Analysis. 58:1845-1866
We present a Fourier analysis of wave propagation problems subject to a class of continuous and discontinuous discretizations using high-degree Lagrange polynomials. This allows us to obtain explic...
