  • Description:
    Real-time data from the National Lightning Detection Network (NLDN) were used in the operational setting at the NWSO at Tucson, Arizona since February of 1995. A summary of the utility of real-time lightning data at Tucson is presented. The operational staff found lightning data to be useful for concise briefings of convective events already occurring. Consensus was that lightning data filled in the gaps that are inherent in the time and space resolutions of the WSR-880 at Tucson and GOES satellite imagery. Lightning data were used for backup power decisions, improved public safety information, to mitigate the effects of radar beam blockage, analyze storm structure, monitor low topped convection, observe thunderstorms in Mexico and summarize national lightning activity. Analysis of lightning data from the monsoon season in 1995 clearly showed the monsoon season progression of convective systems across southeast Arizona as well as the cloud-to-ground lightning hot spots for the season. Lightning data are compactly stored and allow a quick assessment of the overall convective season, convective outbreaks and the ability to identify individual storm systems of interest for study. Also, it is proposed that seasonal averages of lightning data can be used in conjunction with sparse rainfall data across southeast Arizona to improve rainfall estimates.
