Abstract

A stochastic Lagrangian model for concept fluctuations is tested by comparing simulation results with data measured in a small-scale dispersion experiment. To account for the scale of the experiment, the parameterisations of standard deviations and Lagrangian timescales are varied with appropriate constants. The results show a fairly good agreement between the simulated and observed values for the stable cases while discrepancies are observed for the neutral and stable cases.
