Short definition of Turbulence spectrum
Turbulence energy cascade and its expected spectral representation

This is the common definition for Turbulence spectrum, but other definitions maybe discussed within the wiki.

---- MERGE WITH THE SPECTRUM IN FUNDEMENTALS ---

Taylor's Frozen Turbulence for converting temporal to spatial measurements. Convert time derivatives to spatial gradients along the direction of profiling using

<math> \frac{\partial}{\partial x} = \frac{1}{U_P} \frac{\partial}{\partial t} </math> .

Convert frequency spectra into wavenumber spectra using

<math> k = f/U_P </math> and <math> \Psi(k) = U_P \Psi(f) </math> .


  • Missing the y-axi variables
  • Lowest frequency and wavenumber resolvable
