  "term": "Inversion",
  "field": "Environment",
  "definition": "1. An atmospheric condition caused by increasing temperature with elevation, resulting in a layer of warm air preventing the rise of cooler air trapped beneath. This condition prevents the rise of pollutants that might otherwise be dispersed. Trapping pollutants near the ground increases ozone to harmful levels.\n\n2. A layer of warm air that prevents the rise of cooling air and traps pollutants beneath it; can cause an air pollution episode.\n\n3. An atmospheric condition where a layer of cooler air is trapped near the ground by a layer of warmer air above. When the air cannot rise, pollution at the surface also is trapped and can accumulate, leading to higher concentrations of ozone and particle pollution.",
