Abstract: Doppler spectra of a tornado were collected with a radar having a large unambiguous velocity range, ±91 m s?1. Thus for the first time a presentation of nonaliased spectra was possible, showing direct measurement of radial ...

Abstract: A technique to separate ordered flow in a tornadic thunderstorm from the random velocities associated with turbulence is described. The relative importance of the ordered flow shear and turbulence in the broadening of the ...

Abstract: adar echoes from insects, birds, and bats in the atmosphere exhibit both symmetry and asymmetry in polarimetric patterns. Symmetry refers to similar magnitudes of polarimetric variables at opposite azimuths, and asymmetry ...

Abstract: The Next Generation Weather Radar (NEXRAD) may use a 5-min volume scan to monitor thunderstorms and provide hazard warnings. Short-lifetime, low-altitude wind shear near airports is a hazard to safe flights that deserves ...
