Available in PDF, EPUB and Kindle. Book excerpt: An existing Lagrangian stochastic model for dispersion in the convective boundary layer (CBL) was extended in two main ways. First, a model for the mean field dispersion in a rapidly-evolving CBL was developed and calculations of the crosswind-integrated concentration (CWIC) were carried out for a range of conditions. Second, a Lagrangian model for the CWIC and the mean and root-mean-square concentrations was developed that uses the velocity fields from large-eddy simulations as input. Calculations of the CWIC fields were made for three source heights and showed good agreement with the convection tank measurements of Willis and Deardorff. (AN).
