Stochastic wind is generally modelled as white noise, which theoretically contains components of all the frequency in a given bandwidth. You can not assign a particular frequency for the wind.
If you really want to know the frequency components, you can take FFT of the wind time history then you can understand.
I am working on methods in improving the wind turbine power curves. One of the methods is to separate the dynamics of a wind turbine output power into deterministic (actual behavior of a wind turbine) and stochastic (external influences such as turbulence of the wind) behavior of a wind turbine. Attached might be a good reference and starting point for you on studying the stochastic part of the wind turbine output power that considers the turbulence in the wind. The sampling frequency of the data is 1 Hz in this study that seemed to be reasonable for the purpose of output power estimation. Please let me know if it helps. I also am interested to know how far you have done research on this topic.
