Figure 1

Structure of a modeled plume in a cross wind. The wind blows from left to right causing plume deflection to the right. Flame conditions determine initial flame-tip temperature (T _{p 0}), flame density (ρ _i ). vertical velocities(w _i ), and plume half width (b _i ) (Table 1). Fuel moisture, fuel consumption, and ambient vapor pressure determine plume water vapor content (C _wo ). A Gaussian profile is fit to the top-hat (averaged) output of the plume model and used to calculate average plume vapor pressure deficits at a given height above ground.
