Abstract : FAA-funded Doppler weather radar activities during the period 1 October 1985 to 31 March 1986 are reported. The FL-2 Doppler weather radar test bed and associated mesonet system gathered data from various thunderstorms and other weather phenomena in the Memphis, Tennessee, area until late November. During this time, 88 reels of computer tape were recorded representing more than 32 hours of data collection. However, due to the change in weather patterns from summertime airmass to fall cold fronts, there were only five days during which microbursts occurred and four days where gust fronts are known to have occurred. The FL-2 radar and mesonet units were dismantled, packed, and shipped to Huntsville, Alabama, where the system was re-erected in January and February. The system checked during February and March and is participating in the joint Cooperative Huntsville Meteorological Experiments (COHMEX) during June, July, and August. The FL-2 system will continue gathering data throughout the 1986 thunderstorm season in Huntsville, Alabama. Work continued on the analysis of FL-2 and the comparisons of results with the recent NCAR and NSSL experiments. The development of algorithms for the automatic detection and possible prediction of weather related phenomena also continues. It is planned to have at least microburst outflow and gust front algorithms available for testing during the summer season. (Author)
