Abstract : ILITY OF USING DIGITAL RADAR FOR 'REAL-TIME' METEOROLOGICAL AND HYDROLOGICAL APPLICATIONS. Numerical techniques have been developed that enhance the usefulness of weather radar data in these applications. Through the use of digital radar data measured at successive elevation angles in a storm system, an analysis technique is developed that presents a new dimension in mesoscale analysis and gives means of detecting areas of 'explosive development' in severe storms. This indicator presents the three-deimensional characteristics of a storm system in a two-dimension display of vertically-integrated liquid-water content (VIL). Constant altitude reflectivity maps, CAPPI type displays, which are useful in mesoanalysis and/or the study of thunderstorm dynamics, also may be generated from digital radar data. The VIL-analysis technique is used to investigate several tornado-producing meso-systems by use of digital weather radar data collected by the National Severe Storms Laboratory, NOAA, Norman, Oklahoma.
