摘要：
The influence of data determining the initial wind field in a diagnostic wind model with spatial subdomains on the accuracy of concentrations calculated by Lagrangian Advanced Micro-scale Model was analysed. Calculations were carried out for an idealised built environment. Three input datasets were considered: (I) a single inlet wind profile, (II) a single inlet wind profile with additional parametrisation of wind flow around buildings and (III) full wind tunnel wind data. Results show that: in case (I) it is not possible to properly map the position of the pollutant plume; in case (II) the application of additional parametrisation leads to increased accuracy of the mapping of the position of the pollutant plume, in particular in the close vicinity of the source; in case (III) correct mapping of the shape and location of the plume within the entire area was achieved.
