"CIR 4126." Includes bibliographical references (page 4). "The variation of wind with height up to 5000 ft above terrain for morning and afternoon observations is discussed. The wind profiles of five days were averaged and compared to the wind at 5000 ft. The depth of the layer of frictional influence was found to be about 2000 ft in the morning and 3000 ft in the afternoon. A pronounced maximum in the ratio of morning to afternoon wind speeds was noted at about 1000 ft"--Abstract. Winds Speed Canada Measurement. Vents Vitesse Canada Mesure. Canada.
