The persistent cold-air pool study
Webb12 sep. 2014 · We examine the influence of a passing weather system on a persistent cold-air pool (CAP) during the Persistent Cold-Air Pool Study in the Salt Lake Valley, Utah, USA. The CAP experiences a sequence of along-valley displacements that temporarily and partially remove the cold air in response to increasing along-valley winds aloft. The … Webb15 feb. 2024 · The Arve river valley airshed in the French Alps experiences particularly severe air pollution during wintertime stable atmospheric conditions associated with persistent cold-air pools. PM 10 data recorded in the region indicate that the urbanised area of the central basin-shape section of the valley is generally the most polluted, with a …

WebbIn this study, we use data collected in the Salt Lake Valley of northern Utah during the Persistent Cold-Air Pool Study (PCAPS, Lareau et al. 2013) to examine the passage of a shortwave trough during a multi-day CAP. This trough–CAP interaction produced a variety of waves, displacement and fronts that disrupted the otherwise quiescent CAP. In the
