Polarimetric Radar Observations of Hail Formation
Analyses are made of the evolution of selected polarimetric radar data fields during periods immediately preceding the onset of near-surface hail indicators [high reflectivity and low differential reflectivity (Zdr)] in two nonsupercellular northeastern Colorado hailstorms. The primary data were obtained from the 11-cm-wavelength, dual-polarization Colorado State University (CSU)–University of ...
متن کاملHail Detection with Polarimetric Radar
Dual-polarization radars typically transmit horizontally and vertically polarized waves and receive polarized backscattered signals. Because illuminated hydrometeors are not spherical, their radar backscatter cross sections are not the same for the two polarizations. Hydrometeor size, shape, orientation, and thermodynamic phase can be inferred from returned signals. Polarimetric hail algorithms...
متن کاملObservations of oblate hail using dual polarization radar and implications for hail-detection schemes
Coincidental radar measurements and in situ ground-truth observations of large, oblate hail has allowed new insights into the fall mode of oblate hailstones. The effect of the fall mode upon hail-detection algorithms using multi-parameter radar is investigated and discussed, as is the vexed problem of extracting realistic rainfall rates in regions where hail and rain coexist. Observations prese...
متن کاملHigh Resolution Radar Polarimetric Observations of the Lunar South Pole
Introduction: NASA's exploration plans for the Moon are being driven at least in part by the possibility that there may be exploitable deposits of water ice at the lunar south pole. Whether the elevated hydrogen abundance measured by Lunar Prospector corresponds to water ice and, if so, in what form is still a matter of conjecture. Bi-static radar observations with the Clementine orbiter are pu...
متن کاملImpacts of Polarimetric Radar Observations on Hydrologic Simulation
Rainfall estimated from the polarimetric prototype of the Weather Surveillance Radar-1988 Doppler [WSR-88D (KOUN)] was evaluated using a dense Micronet rain gauge network for nine events on the Ft. Cobb research watershed in Oklahoma. The operation of KOUN and its upgrade to dual polarization was completed by the National Severe Storms Laboratory. Storm events included an extreme rainfall case ...
