Abstract
The results of the wind observation in the lower atmosphere made on a tower are described. This observation was made being connected with the cooperated observation of the tropospheric propagation of microwaves in Kanto district. The diurnal variations of the mean wind speeds with height were tabulated. The mean wind speed profiles follow the logarithmic law in the midday when the temperature lapse rate is adiabatic, but at night and in morning the wind speed profiles consist of two parts in each of which logarithmic law holds.
