This paper presents some dynamic characteristics of an opto-electronic cup anemometer model in relation to its response to the wind turbulence.It is based on experimental data of the natural wind turbulence measured both by an ultrasonic anemometer and two samples of the mentioned cup anemometer.The distance constants of the latter devices measured
