Model chain for buoyant plume dispersion

A new original software interface between the WRF mesoscale meteorological model and the SPRAYWEB dispersion model has been developed. The model chain was designed an highly responsive tool for risk assessment and emergency-response purposes. The model interface reads the wind and temperature field provided by WRF and interpolate them on a fixed-in-time grid, which is the input to the dispersion model. Furthermore, it calculates the turbulence-parameter vertical profiles, based on the surface-layer data provided by WRF. In this work we simulate the dispersion of a high- buoyancy plume. The model chain performances were tested against the Bull-Run dataset.
