Turbulence Kinetic Energy (TKE) Calculator

Introduction : This calculator calculates the intensity of turbulence. Turbulent energy continuously drives eddies from the greatest to the least by wind shear (mechanical) and thermals (buoyant). The TKE equation requires the standard deviations of air gust, vertical velocity, and . The standard deviations require the fricton velocity which uses the drag coeffiecent in order to solve. In this calculator, you have five input values:
  1. Aerodynamic Roughness Length (zo)
  2. Wind Speed (M10)
  3. Height of Air (z)
  4. Depth of Air (h)
  5. Stability of the air (statically stable, statically neutral, statically unstable)

The algorithm for the whatever it is is:
