Cold air pools which form in valley bottoms on clear, calm nights intensify diurnal temperature minima and induce strong stability, with the possibility of dangerous build-up of pollutants when cold air pools persist for a long time. Cold air pools within small-scale hills exhibit different dynamical behaviour to those in large mountain-walled valleys. The dynamics of cold air pools, and their effect on cold pool morphology and diurnal cycle, are investigated as a function of atmospheric conditions and changing scale between these limits.
