Particle Dispersion vs. Concentration Results +3 hr Particle Dispersion +3 hr Particle Concentration To the right is the resulting concentration pattern associated with the Top-Hat Puff / Particle distribution from the previous example over Florida. Note the concentration pattern is very similar to the particle pattern and, as expected, the highest concentrations are over the same area that has the highest density of particles. Over central Florida, where the particles are spaced farther apart, the concentrations are less. 7
