Abstract: We developed a fluctuating plume model able to evaluate all the higher order moments of concentration only requiring the knowledge of the first one. The simple algorithm used to calculate the meander centroid component is independent of the method used to obtain the mean concentration field and makes the computational time lower than most meandering plume model versions. Thus, it is especially suitable for practical applications.

Keywords: atmospheric dispersion modelling; fluctuating plume model; concentration fluctuations; environmental pollution; air pollution; air quality.
