Abstract

A mass-consistent meso-scale wind field model was applied to the complex ter- rain area of Grand Canyon for 1990 Winter Salt River Project's Navajo Gen- erating Station (NGS) Visibility Study. The model interpolates hourly grided mean wind field as an input field for trajectory model to simulate the plume emissions for meso-scale air pollution studies using network measured surface and upper air meteorological data. Three flow types associated with the di- rectly, indirectly, and non transports of the NGS plume emissions towards the Grand Canyon National Park were examined. Predicted plume streaklines from a trajectory model were
