Chaos and 'Bursting' in the planetary boundary layer

A one-dimensional, 'flat' terrain planetary boundary layer (PBL), of the form designed by A.K. Blackadar, was studied to examine the inconsistent breakdowns of PBL. The violent burst influence is observed mainly in the lowest tens of meters of PBL, where an alternation between consecutive periods of laminar and turbulent flow direct quick cooling or heating of the near-surface air temperature in some situations. The lack of periodicity of violent bursts and their high responsiveness to the early conditions of the coercion hint that PBL can act as a deterministic chaotic process in certain conditions.
