Weather Radar Studies.
Abstract
FAA-funded Doppler weather radar activities during the period 1 January to 31 March 1985 are reported. The test-bed Doppler weather radar system measurements in Olive Branch, Mississippi, commenced following the installation of an improved lightning protection system. Clutter suppression testing showed that the objective of 50-dB suppression was obtained in the field against appropriate fixed targets. Weather measurements were conducted on a number of cold front passages with attendant prefrontal lines of showers and thunderstorms. The Lincoln mesonet was recalibrated at Lincoln in January and February and then installed at the site in late February. The mesonet was fully operational in March. The 1984 peak wind speed data from the mesonet and the Memphis International Airport LLWAS data were analyzed preliminarily to determine wind shear characteristics in the Memphis area. Doppler weather radar data from the National Center for Atmospheric Research JAWS program and the National Severe Storms Laboratory are being analyzed to develop low-altitude wind shear detection algorithms. Analysis of the data collected in the 1983 Boston area coordinated aircraft-Doppler weather radar turbulence experiment commenced. Work continued on the development of weather radar products for the Central Weather Processor with particular emphasis on the correlation tracking and extrapolated weather map algorithms. Keywords include: Weather radar; Low-altitude wind shear; NEXRAD; Central weather processor; Aviation weather products; and Turbulence.
