Abstract: Several methods used to estimate rainfall rate R are surveyed. The distribution N(D) of drop sizes is of central importance in determining the reflectivity factor Z, attenuation rate K, and R. With single-parameter measurement ...

Abstract: The theory of spaced-antenna interferometry (SAI) is formulated to detect and locate deterministic objects and reflectivity inhomogeneities embedded within the phased-array weather radar?s resolution volume V6 and to improve ...

Abstract: Contrary to accepted usage, the second central moment of the Doppler spectrum is not the sum of the second central moments of individual spectral broadening mechanisms. A rigorous theoretical derivation of the spectrum ...

Abstract: Doppler radar and a 444 m tall instrumented tower provide a detailed view of the kinematic and thermodynamic structure of a solitary gust. A study of the data fields, and comparison with theoretical and laboratory work ...

Abstract: The theory of measuring crossbeam wind, shear, and turbulence within the radar?s resolution volume V6 is described. Spaced-antenna weather radar interferometry is formulated for such measurements using phased-array weather ...

Abstract: Doppler radar data collected each spring in 1979?1984 with the two Doppler radars operated by the National Severe Storms Laboratory (NSSL) are used to investigate the asymmetry of low-altitude divergent outflows of convective ...

Abstract: Recent operation of the Valley Forge-Wallops Island bistatic radar link during two days characterized by light rain and drizzle provided some detailed, bistatically derived information on atmospheric structure in the ...

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: Weather radar observations of stratiform precipitation often reveal regions having very large measured Doppler spectrum widths, exceeding 7, and sometimes 10, m s?1. These widths are larger than those typically found in ...
