Weather Radar Studies.
Abstract
FFA-funded Doppler weather radar activities during the period 1 April to 30 June 1985 are reported. The test-bed Doppler weather radar system making measurements in Olive Branch, Mississippi, was fully operational. Additionally, the University of North Dakota C-band Doppler weather radar commenced measurements. Weather measurements were conducted on a number of cold front passages with attendent prefrontal lines of showers and thunderstorms and on scattered air mass thunderstorms. Some 17 microbursts were observed during the radar operation with the bulk of the microburst occurring in late June. Thirty-one gust fronts were observed as well. The University of North Dakota Citation aircraft made airborne turbulence measurements on eight days in the period mid-May to mid-June. The Lincoln mesonet was fully operational throughout the period. The 1984 peak wind speed data from the mesonet and the Memphis International Airport LLWSAS data have been analyzed to determine ground level wind-shear characteristics in the Memphis area. Doppler weather radr 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 continued of the data collected in the 1983 Boston area coordinated aircraft-Doppler weather radar turbulence experiment. 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 and an algorithnm to generate vertical cross sections along a user specified axis.
