Gaussian plume models

From Glossary of Meteorology



Gaussian plume models

Models for the dispersion of gases or particles, usually from a point source.

The concentration inside the plume is predicted using Gaussian statistics, with the center line of the plume (the point source advected by the mean flow) at the maximum of the Gaussian distribution, and with the standard deviation of the Gaussian distribution an increasing function of time or downwind distance.
