Cup Anemometer Response to Fluctuating Wind Speeds

An investigation is made into cup anemometer response to fluctuating wind speeds. The anemometer overruns under these conditions and the percentage overrun depends on the wind speed, and the frequency and amplitude of the fluctuations. An estimate of this overrun in the real atmosphere, i.e., the &q...

Zusammenfassung:An investigation is made into cup anemometer response to fluctuating wind speeds. The anemometer overruns under these conditions and the percentage overrun depends on the wind speed, and the frequency and amplitude of the fluctuations. An estimate of this overrun in the real atmosphere, i.e., the "u error", is made and found to be of the order of 1% for a typical micrometeorological anemometer.
