Sažetak
The Atmospheric Lagrangian Particle Stochastic (ALPS) dispersion model was created as an experimental student project and tested under idealized and complex atmospheric and topographic conditions. The model is based on statistical approach and uses an Eulerian meteorological model output fields to estimate Lagrangian scales and turbulence. Dispersion of a passive scalar in the atmosphere is simulated by calculating a large number of Lagrangian particle trajectories. ALPS was built based on the same set of basic equations as in the LAP model from Koracin et al. (1998, 1999). All other issues in the model were left for the students to research and implement. Series of idealized tests were conducted and it has been shown that ALPS correctly responds to different atmospheric stability conditions and their respective level of turbulence. The well-mixed criterion was met by adding a drift correction term to the vertical component of the subgrid-scale velocity. In the future developments of this model complete solution for all conditions in the convective PBL must be solved prior to its applications to experiments in such conditions.
