Wind shear studies in the lower atmosphere Using forward scattering sodar system

Abstract

For study of wind shear, a forward scattering sodar system has been set up at the National Physical Laboratory. New Delhi. It has the capability to sense both temperature and wind inhomogeneities exclusively. The observations made for the period March-July 1983 have shown that a large part of the spiky top stable layer, rising layer and elevated/multilayer structures with or without wave motion have predominant with shear component over and above the contribution due to thermal inhomegenities. Duration, height and time of occurrence and the extent of observed wind shear have been analysed and reported. Studies have also been made of the hazardours and non-hazardous nature of the wind shear with respect to weather condition prevalent in the atmosphere.
