Changes in the local atmospheric circulation are analyzed by calculating three different cases: the circulation regime for the actual topography, and the resulting flows for two different modifications on the southwestern mountains of the city (Ajusco zone) . INTRODUCTION Mexico City's air pollution problem has recently
