Cathedral City's air quality reflects the Coachella Valley's enclosed desert basin between the San Jacinto and Little San Bernardino mountains in the Palm Springs corridor, with vehicle emissions from SR-111 the primary local source. The Banning Pass wind provides powerful periodic ventilation from the west, while under calm conditions the valley's near-complete mountain enclosure creates persistent temperature inversion episodes and windblown desert dust contributes elevated PM10 throughout the year.
