Abstract

Wind power spectral density measured in the lower and middle troposphere under zonal flow conditions is consistent with a −5/3 slope to frequencies as high as 10−2 Hz. By conversion of frequency to a spatial coordinate it is found that a satellite-borne lidar when averaging such winds over a 300 km grid scale would measure the synoptic-scale wind with a 98% representativeness index.
