1. A turbulence sensor comprising:

  • thermal anemometer airspeed transducer means providing fast response airspeed signal output;

    said airspeed signal output operatively connected to bandpass filter means thereby providing defined bandwidth turbulence component signal;

    said turbulence component signal operatively connected to root-mean-square signal measurement means thereby providing measurement of turbulence eddy kinetic energy;

    said airspeed signal output operatively connected to lowpass filter means thereby providing mean airspeed component signal, anddivision means whereby said measurement of turbulence eddy kinetic energy is divided by said mean airspeed component signal thereby providing measurement of turbulence intensity.
