The persistent cold-air pool study
Webbmultiday cold-air pools that affect air quality in urban basins. A cold-air pool (CAP), defined as a topographic depression filled with cold air, occurs when atmospheric processes favor cooling of the air near the surface, warming of the air aloft, or both. The resulting stable stratification prevents the air within the basin from mixing with ...
