In this study, two different parameterisations for wind velocity-component standard deviations are compared. The results of model simulations using these parameterisations are compared in terms of mean concentration and concentration standard deviation, using statistical indexes and scatter- and qq-plots.
In this work, we compare two different parameterisations for the wind velocity-component standard deviations. The first one is the (Hanna 1982) parameterisation, while the second is the (Scire et al. 2000) parameterisation, which provide the proper values and vertical structure for the wind standard deviations in the convective, neutral and stable layers, needed as input the Lagrangian stochastic model SPRAYWEB. The results of the model simulations carried out using the two parameterisations are compared, in terms of both mean concentration and concentration standard deviation, by evaluating some statistical indexes and trough scatter- and qq-plots.
