dc.description.abstract
This dataset contains statistics of resolved-turbulence simulation for turbulent Ekman flow,
the flow over a flat rotating plate. The five simulation cases differ by the strength of stable
density stratification imposed as a Dirichlet boundary condition at the surface, quantified
by a Froude and Richardson numbers. Here, cases are labelled by their Froude numbers as fr02, fr05, fr07, fr09, fr18. The choice of Re_Λ = 5 × 10^5 corresponds to an Ekman-based Reynolds-number of 1000 and a friction Reynolds number Re_τ ≈ 1400 for the neutrally stratified case. The turbulent flow is simulated with tLab using a computational grid with dimensions of 3072 x 512 x 6144 and a spatial resolution at the surface of approximately 4.1 × 4.1 × 1.05 wall units. The horizontal domain size is scaled to 1.08 in terms of Rossby radius. This dataset contains a PDF file outlining the simulation setup and description of the variables contained in the netCDF files.
