High resolution numerical models for smoke transport in plumes from wildland fires - poster

A high-resolution large-eddy simulation model is employed to examine the fundamental dynamics of buoyant plumes arising from heat sources representative of wildland fires in the presence of a vertically sheared ambient atmospheric crosswind. Time-averaged plume trajectories…

Present-day climate forcing and response from black carbon in snow

We apply our Snow, Ice, and Aerosol Radiative (SNICAR) model, coupled to a general circulation model with prognostic carbon aerosol transport, to improve understanding of climate forcing and response from black carbon (BC) in snow. Building on two previous studies, we account…

Numerical simulations of grass fires using a coupled atmosphere-fire model: dynamics of fire spread

Numerical simulations using a coupled atmosphere-fire model (called HIGRAD/ FIRETEC) are examined to investigate the dynamics of fire behavior in grasslands, focusing specifically on the relative roles and contributions of radiative and convective heat transfer and the…
