Summary

Matlab implementation of the solution to the Ekman equations in the atmospheric boundary layer. The flow is assumed horizontal and homogeneous. however, a height-dependant eddy viscosity can be modelled. The solutions are provided in one-dimension.

Content

The submission includes

  • The function EkmanAnalytic that provides analytics solution of Ekman's equations for a constant eddy viscosity in the atmospheric boundary layer.
  • The function solveEkman that numerically solves Ekman's equations with an explicit finite difference scheme and allows the use of height-dependant eddy viscosity. The numerical implementation is partly inspired by [1].
  • An example file Example0.mlx and reproduces some of the figures displayed in ref [2]

Any question, suggestion or comment is welcomed.
