A three‐dimensional second‐order closure dispersion model is used to simulate the plume behaviour of a passive contaminant in a convective boundary layer. A time‐splitting finite element method together with a non‐linear filtering scheme is used to solve the three‐dimensional second‐order closure transport equations. The model results show good agreement with laboratory data for a ground level source.
