The aim of this research was to detect cold‐air pool (CAP) days during winter and quantify the synoptic situations that produce decoupling between free air and valley bottom temperatures in the Cerdanya basin in the eastern Pyrenees (Spain). Patterns prone to CAP (see figure) are defined by an anticyclonic ridge over the Iberian Peninsula and absence of surface wind in Cerdanya, especially in December and January. Warm air advection from the south is also associated with some of the patterns.
