Abstract

The power spectrum of the wind is estimated from independent wind measurements taken at an altitude of 1,500 ft above the ground in the frequency band from 0.0625 to 1.5 cycles hr–1. Wind data were obtained simultaneously from radar tracking equipment and from wind sensors on a nearby tower. These data were collected at 20-min intervals over a 5-day period.

Analyses of the wind spectra and coherence indicated a good correspondence in the two time series, considering that the data were obtained at slightly different locations and by completely independent measurements. It is concluded that radar wind-finding measurements can provide valid estimates of the wind spectrum in the frequency band analyzed.
