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

Taylor's Frozen Turbulence for converting temporal to spatial measurements. Convert time derivatives to spatial gradients along the direction of profiling using
[math]\displaystyle{ \frac{\partial}{\partial x} = \frac{1}{U_P} \frac{\partial}{\partial t} }[/math] .
Convert frequency spectra into wavenumber spectra using
[math]\displaystyle{ k = f/U_P }[/math] and [math]\displaystyle{ \Psi(k) = U_P \Psi(f) }[/math] .
- Missing the y-axi variables
- Lowest frequency and wavenumber resolvable
