Improvements to melting snow behavior in a bulk microphysics scheme
Snow falling into a melting layer will eventually consist of a fraction of meltwater and hence change its characteristics in terms of size, shape, density and fall speed. Most...- publication PDF

Ion-neutral coupling effects on low-latitude thermospheric evening winds
We examine the forces that determine zonal wind structure in the low-latitude evening thermosphere and its relation with ion-neutral coupling. These winds drive the evening F...- 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
