Over the past decade, concern over potential global warming has focused attention on the emission of greenhouse gases into the atmosphere, and there is an active debate concerning the desirability of reducing emissions. At the heart of this debate is...

The larvae of jewel beetles of the genus Melanophila (Buprestidae) can develop only in the wood of trees freshly killed by fire. To arrange this, the beetles need to approach forest fires from as far as 50 kilometers away. They are the only buprestid...

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...

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...

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-...
