The persistent cold-air pool study
Webb1 sep. 2024 · Modelling studies of several persistent Salt Lake Valley cold-air pools during PCAPS were also conducted by Wei et al. (2013), Lu and Zhong (2014), and Foster et al. (2024), but these simulations were run at typical mesoscale model resolutions (1–3 km Δx) and did not occur during a prolonged period of turbulent erosion on the upper boundary … Webb1 dec. 2010 · Research Goals: * identify fundamental processes that lead to complete evolutionary cycle of persistent cold-air pools in the Salt Lake basin, * perform …
