C-Band Dual-Polarization Radar Observables in Rain
Publisher: American Meteorological Society
Abstract: C-band dual-linear polarization radar observables are simulated from disdrometer measurements in rainfall and from gamma-model raindrop-size distributions. It is shown that rainfall is clustered in certain sections of ...
Cloud Ice Crystal Classification Using a 95-GHz Polarimetric Radar
Publisher: American Meteorological Society
Abstract: Two algorithms are presented for ice crystal classification using 95-GHz polarimetric radar observables and air temperature (T). Both are based on a fuzzy logic scheme. Ice crystals are classified as columnar crystals (CC), ...
Radar Polarimetric Backscattering Properties of Conical Graupel
Publisher: American Meteorological Society
Abstract: Conical graupel is modeled using sphere-cone-oblate spheroidal shapes for the purpose of computing their backscattering properties at a wavelength of 10 cm in terms of the radar polarimetric observables, reflectivity ...
Disdrometer Measurements during an Intense Rainfall Event in Central Illinois: Implications for Differential Reflectivity Radar Observations
Publisher: American Meteorological Society
Abstract: Empirical relationships for estimating rainfall rate, liquid water content and median volume diameter from radar measurements of reflectivity factor and differential reflectivity are derived from a disdrometer record of a ...
Remote Sensing of Hail with a Dual Linear Polarization Radar
Publisher: American Meteorological Society
Abstract: A technique for the remote sensing of hail with an S-band dual linear polarization radar is described. The method employs a new hail signal HDR, which is derived from disdrometer measurements of raindrop size distributions. ...
Rain-Rate Estimation in the Presence of Hail Using S-Band Specific Differential Phase and Other Radar Parameters
Publisher: American Meteorological Society
Abstract: Multiparameter radar measurements were made during a heavy rainfall event accompanied by hail in Colorado. Rainfall rates R and accumulation Σ for this event were estimated using S-band specific differential phase KDP, ...
A Differential Reflectivity Radar Hall Measurement Technique: Observations during the Denver Hailstorm of 13 June 1984
Publisher: American Meteorological Society
Abstract: A differential reflectivity radar technique for observing hailstorms is demonstrated using measurements obtained during the 13 June 1984 Denver hailstorm. The hail regions of the storm are identified with the differential ...
Effects of Raindrop-Size Distribution Variation within the Radar Scattering Volume on Radar Observables
Publisher: American Meteorological Society
Abstract: Dual linear polarization weather radars measure as primary observables the mean power P?H, and P?V, corresponding to returns at horizontal and vertical polarizations, respectively. Differential reflectivity ZDR is defined ...
Bistatic Dual-Polarization Scattering from Rain and Hail at S- and C-Band Frequencies
Publisher: American Meteorological Society
Abstract: Bistatic dual-polarization radar parameters at S- and C-band frequencies are simulated for rain and hail. The goal is to determine their potential for discriminating the two precipitation types and for estimating the ...
Rainfall and Clutter Discrimination by Means of Dual-linear Polarization Radar Measurements
Publisher: American Meteorological Society
Abstract: The presence of undetected mixed-phase precipitation or superimposed intense clutter can cause serious errors in the estimation of rainfall rate and other parameters of precipitation occurring in the radar scattering volume. ...
