The N0 Jump of Raindrop Spectra
Publisher: American Meteorological Society
Abstract: Raindrop spectra are measured with an electromechanical raindrop spectrometer, responding to drops >0.3 mm in diameter. The radar reflectivity profile is measured simultaneously with a 5-cm vertically pointing radar. ...
Peaks in Raindrop Size Distributions
Publisher: American Meteorological Society
Abstract: The multipeak behavior of raindrop size distributions has been studied. Peaks have been found for distinct drop diameters: 0.7, 1.0, 1.9, and possibly 3.2 mm. The probability is about 65% that at least one of these peaks ...
The Kinetic Energy of Hailfalls. Part III: Sampling Errors Inferred, from Radar Data
Publisher: American Meteorological Society
Abstract: The representativeness of hailfall kinetic energies derived from point measurements of networks is studied by means of radar data of hail cells. The 202 cells were observed within a radius of 60 km from the 10 cm radar. ...
Raindrop Size Distribution and Sampling Size Errors
Publisher: American Meteorological Society
Abstract: The standard deviation of the rain intensity R and the reflectivity factor Z are derived theoretically for R and Z values which are calculated from measured distributions of raindrop size. The derivation is based on the ...
Radar Hall Profiles in Switzerland
Publisher: American Meteorological Society
Abstract: Radar reflectivity profiles of 154 hail cells have been investigated. An average profile (the hail profile) has been derived. A global method has been used since the hail profile is designed to be applied to global hail ...
Hail and Raindrop Size Distributions from a Swiss Multicell Storm
Publisher: American Meteorological Society
Abstract: Time-resolved hail and raindrop size distributions measured simultaneously during a multicellular hailstorm are presented. The time variation of the size distributions allowed a detailed analysis of the structure of the ...
The Kinetic Energy of Hailfalls. Part I: Hailstone Spectra
Publisher: American Meteorological Society
Abstract: The relationship between radar reflectivity and kinetic energy flux (Z-?) is investigated by means of analyses of hailstone size distributions measured with hail spectrometers. Semi-empirical relations assuming monodisperse ...
Criteria for the Detection of Hail Cells
Publisher: American Meteorological Society
Abstract: One of the Soviet seeding criteria used to detect hail cells at an early stage of development is examined. The radar history of 195 strong convective cells is studied and compared with information of a dense hailpad network ...
