Simulation of short-range diffusion experiment in low-wind convective conditions
(2002)
A previously obtained analytical solution to model the short-range dispersion of pollutants in low winds from surface releases has been used to simulate diffusion tests conducted during winter in weakly convective conditions ...
Surface layer turbulence processess in low wind speeds over land
(1995)
The atmospheric diffusion in the tropics is generally associated with low wind speeds, typically of magnitudes less than 3 m s-1. Low wind speeds would cause significant free convection in the daytime and strong stable, ...
Comparison of sigma schemes for estimation of air pollutant dispersion in low winds
(1995)
The dispersion coefficients are key parameters in most of the air quality models and their use in
low wind speed conditions involves some degree of uncertainty. Various estimates of dispersion parameters are discussed for ...
Statistical evaluations of sigma schemes for estimating dispersion in low wind conditions
(1996)
Previously described sigma schemes for the stimation of dispersion parameters in low wind- speed situations are evaluated statistically with the data obtained in a series of diffusion experiments (conducted by U.S. National ...
