WIND SHEAR AND REFLECTIVITY GRADIENT EFFECTS ON DOPPLER RADAR SPECTRA-2

Abstract

The mean and variance of the doppler or pule-fluctuation spectrum are of meteorological interest, for example, in measurements of updrafts, winds, wind shear and turbulence. The present discussion concerns situations in which a component of the shear vector is along the beam and both the reflectivity and velocity of the scatters vary across one dimension of the beam. Such cases occur with vertically pointing beams in convective storms and at all elevation angles in stratiform precipitation accompanied by wind shear and vertical reflectivity gradients.
