Numerical simulation of "an American haboob"
A dust storm of fearful proportions hit Phoenix in the early evening hours of 5 July 2011. This storm, an American haboob, was predicted hours in advance because numerical,...- publication PDF

Improved techniques for evaluating GCM cloudiness applied to the NCAR CCM3
Evaluations of GCM cloudiness typically compare climatological output with observations, but averaging over time can obscure the presence of compensating errors. A more...- publication PDF

Multimodel assessment of the factors driving stratospheric ozone evolution...
The evolution of stratospheric ozone from 1960 to 2100 is examined in simulations from 14 chemistry-climate models, driven by prescribed levels of halogens and greenhouse gases....- publication PDF

A nonoscillatory discontinuous Galerkin transport scheme on the cubed sphere
The discontinuous Galerkin (DG) method is high order, conservative, and offers excellent parallel efficiency. However, when there are discontinuities in the solution, the DG...- publication PDF
