WebbAbstract. Air pollutant accumulations during wintertime persistent cold air pool (PCAP) events in mountain valleys are of great concern for public health worldwide. … WebbCold-air pools (CAPs) occur when cold air is topo-graphically trapped within a valley or basin and with warmer air aloft. CAPs are associated with limited mixing and weak …
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 … Webb17 dec. 2024 · Processes of cold-air pool (CAP) erosion in an Alpine valley during south foehn are investigated based on a real-case large-eddy simulation (LES).
