Abstract |
The research presented concerns the development of a simulation model for smog. The preparation and conversion to digital form of contour maps of surface wind speed and direction (isotachs and streamlines, respectively) and of the height of a temperature inversion base--in each case hourly representations, were achieved. Several approaches to the calculation of the wind field aloft, one of which appears to be a useful method for the automatic generation of these wind fields were also explored. For inversions, surface wind fields, winds aloft, and turbulent diffusivities for the days of validation, the following are described: the computational and data requirements; the nature of the available data base; efforts in satisfying the stated requirements; and the deficiencies in approach and, thus, recommended future efforts.
