SEMINAR: MPO special seminar, Tuesday 3PM

["David S. Nolan" <dnolan@rsmas.miami.edu>]

There will be a special MPO seminar at 3PM on Tuesday in the
SLAB seminar room:


High-resolution Wave Propagation Method applied to Meso- and Micro-scale
Atmospheric Flows

Nash'at N. Ahmad

NASA Langley Research Center,
Hampton, Virginia

The Euler equations are solved for non-hydrostatic atmospheric flow
problems in two dimensions using a high-resolution wave propagation
method.  The design and implementation of the Riemann solver used
for computing the Godunov fluxes is discussed in detail.  The flow
solver is conservative and able to resolve regions of large gradients
without introducing dispersion errors by enforcing the total variation
diminishing property.  The methodology is validated against benchmark
cases for non-hydrostatic atmospheric flows.  Comparisons are made with
solutions obtained from the National Center for Atmospheric Research's
state-of-the-art numerical model.  Examples of computationally
efficiency achieved via adaptive mesh refinement are discussed using
cases of the Euler equations as well as the scalar transport equation.
