Abstract: The feasibility of using the next generation weather radar (NEXRAD) system to detect low-altitude wind shear near airports is investigated. We compare surface-measured horizontal shear with that observed aloft with Doppler ...

Abstract: The capability of Doppler weather radars to short-term forecast the initiation of thunderstorms and the onset of cloud-to-ground (CG) lightning is examined. Doppler weather radar data from 28 thunderstorms were analyzed ...

Abstract: Doppler radar data collected each spring in 1979?1984 with the two Doppler radars operated by the National Severe Storms Laboratory (NSSL) are used to investigate the asymmetry of low-altitude divergent outflows of convective ...

Abstract: A Doppler velocity dealiasing algorithm is described that processes one radial at a time by comparing that radial with a previous radial. This technique has worked reliably on numerous Doppler radar datasets for clear air, ...

Abstract: The question of who is the ?best? forecaster in a particular media market is one that the public frequently asks. The authors have collected approximately one year's forecasts from the National Weather Service and major ...

Abstract: During the summer of 1996, the National Weather Service (NWS) provided weather support for the Centennial Olympic Games in Atlanta, Georgia. This weather support effort presented many challenges, particularly in the area ...

Abstract: The Federal Aviation Administration's Terminal Doppler Weather Radar (TDWR) system was primarily designed to address the operational needs of pilots in the avoidance of low-altitude wind shears upon takeoff and landing at ...

Abstract: An enhanced hail detection algorithm (HDA) has been developed for the WSR-88D to replace the original hail algorithm. While the original hail algorithm simply indicated whether or not a detected storm cell was producing ...

Abstract: This paper discusses some important issues and problems associated with evaluating the performance of radar-based severe storm detection algorithms. The deficiencies of using Storm Data as a source of verification are ...

Abstract: This paper describes the Verification of the Origins of Rotation in Tornadoes Experiment planned for 1994 and 1995 to evaluate a set of hypotheses pertaining to tornadogenesis and tornado dynamics. Observations of state ...
