Abstract
The structure of strong wind gusts in the surface air layer over an urban territory and a natural landscape is analyzed. Experimental data obtained with ultrasonic anemometers-thermometers at altitudes of 5 and 10 m (natural landscape) and 17 m (urban territory) above the surface have been examined. Contributions of the longitudinal and transverse components to wind gusts have been estimated. Motions to the right from the main flow and from top down have been found to predominate somewhat in wind gusts.
