Abstract: Meteorological instruments which are designed to measure the size spectra of hydrometeors such as hailstones or raindrops or instruments designed to measure cumulative precipitation such as raingages can produce errors if ...

Abstract: Modern Doppler weather radars use clutter filtering to reduce the strength of ground targets and enhance the detection of meteorological echoes. WSR-88D [NEXRAD (Next Generation Radar) and TDWR (Terminal Doppler Weather ...

Abstract: Microbursts continue to pose a serious problem to the aviation industry. Fortunately, Doppler weather radars are capable of detecting microbursts quite successfully. This study gives the results of a comparison of 84 ...

Abstract: An equation used to describe the calibration of an instrument is either of an arbitrary nature or based upon physics. The latter, which we call behavioral modeling, often provides a much better fit to the calibration than ...

Abstract: In using a dual-wavelength radar system to detect hail, erroneous positive hail signals can result because of the stronger attenuation of the shorter wavelength radar beam. We present a simple technique to correct for ...

Abstract: The detection of hail with a dual-wavelength radar system can succeed only when the two essentially independent radars used are correctly calibrated, when attenuation is correctly handled, and when the radars sample the ...

Abstract: Microburst rotation can be determined by measuring the difference in azimuths between the maximum approaching and maximum receding velocity centers on a Doppler radar. Nonrotating microbursts would have these centers exactly ...

Abstract: Radar data collected during the seeding experiment of the National Hail Research Experiment are used in a search for possible effects of seeding. Two types of variables, denoted by P and Q, are defined as daily integrals ...
