Abstract
We used sodar data to obtain spatial, diurnal and seasonal variability of wind speed variances. Comparison of measurements at two sites in Moscow megalopolis and at the rural site (45 km from Moscow) was carried out. A good agreement between sodar and in-situ measurements by ultrasonic anemometer in rural and urban observations was obtained. Variances of radial velocities measured at sodar inclined antennae were compared with vertical wind variance as well as with wind components variances by sonic data. Experience in measuring of meso-scale wind variability by averaged on short time intervals data is demonstrated. Measurement of other statistical characteristics like vertical wind variances is discussed.
