WebbAs mechanical turbulence increases, the Richardson number approaches zero, and the dispersion of a smoke plume decreases, approaching neutral stability where (∂θ/∂ z) = 0. Finally, as the Richardson number becomes positive, vertical mixing ceases, and mechanical turbulence is dampened. http://sites.bsyse.wsu.edu/joan/teaching/bsyse556/W5/L5Stu.pdf

WebbThe Bulk Richardson Number (BRN) is an approximation of the Gradient Richardson number. The BRN is a dimensionless ratio in meteorology related to the consumption of turbulence divided by the shear production (the generation of turbulence kinetic energy caused by wind shear) of turbulence.
