Abstract: The temporal and spatial distributions of lightning activity associated with specific synoptic regimes of low-level wind flow were analyzed as part of an experiment to develop improved statistical thunderstorm forecasts ...

Abstract: Relationships between network lightning data and hourly thunderstorm observations were examined for the northeastern United States, Oklahoma, Florida, and the western United States to provide additional information on the ...

Abstract: A numerical model is developed to compute three-dimensional trajectories from operational wind forecasts generated by the six-layer primitive equation model of the National Meteorological Center. Detailed 24-hr forecasts ...

Abstract: Over two million cloud-to-ground lightning strike locations for the period from mid-June through mid-September for the 1983?84 summer seasons were evaluated to determine the large-scale climatological characteristics of ...

Abstract: Archived lightning data from the Bureau of Land Management automated network of direction-finding stations in Alaska were examined to determine the seasonal, diurnal, and spatial distributions of cloud-to-ground lightning, ...

Abstract: Data for nearly 2 million lightning flashes recorded during the 1985?86 warm seasons by the National Severe Storm Laboratory's (NSSL's) lightning strike locating network were evaluated to determine some of the climatological ...

Abstract: Probability equations were developed for 12?36 h forecasts of thunderstorms, severe local storms, and major or family tornado outbreaks. The equations were derived by applying screening regression techniques to relate ...

Abstract: Relationships were established between lightning location data and surface hourly observations of thunderstorms for 132 stations in the northeastern United States. The relationships are based on statistics derived from 2 ...
