A historical background on research in CBL turbulence

Turbulence studies rely heavily in experimental data, and that data is almost always presented in terms of dimensionless variables. Results become ‘universal’ (applicable to all flows in a specified class) when properly scaled. In boundary layer meteorology we currently have two approaches to scaling: one based on the conceptual model provided by the statistical fluid mechanics model; and the other based on concepts from complex dynamical systems (CDS). This lecture will give an historical account of how this division arose, and present some new results from a convective boundary layer using the CDS conception of turbulence.
