Abstract: The mean annual flash density, thunderstorm duration, and flash rates were calculated using 121.7 million cloud-to-ground lightning flashes in the continental United States for the period 1989?96. Florida had flash densities ...

Abstract: Cloud-to-ground lightning data have been analyzed for the years 1995?97 for the contiguous United States for total flashes, positive flashes, the percentage of positive lightning, peak currents for negative and positive ...

Abstract: The physical and geographical characteristics of over 216 million cloud-to-ground lightning flashes recorded during the first decade (1989?98) of operation of the National Lightning Detection Network (NLDN) covering the ...

Abstract: The percentage of negative lightning flashes composed of a single stroke is examined. This percentage is estimated from data reported by the U.S. National Lightning Detection Network (NLDN) for Florida and New Mexico and ...

Abstract: loud-to-ground (CG) lightning data have been analyzed for the years 2001?09 for North America, which includes Alaska, Canada, and the lower 48 U.S. states. Flashes recorded within the North American Lightning Detection ...

Abstract: Cloud-to-ground lightning data have been analyzed for the years 1998?2000 for North America (Canada plus the contiguous United States) for all ground flashes, positive flashes, the percentage of positive lightning, peak ...

Abstract: Over a decade of monitoring mesospheric transient luminous events (TLEs) above U.S. high plains storms confirmed sprites are almost exclusively associated with positive polarity cloud-to-ground lightning (+CGs). Following ...
