Abstract: A quantitative analysis has been completed of the first time-resolved spectra of return strokes. All values refer to approximately a 10-m section of the return-stroke channel. Ten return-stroke spectra, eight with 5-?sec ...

Abstract: The development of the National Lightning Detection Network (NLDN) can be traced from the initial funding by the Electric Power Research Institute in June 1983. This support, when coupled with a small National Science ...

Abstract: The National Lightning Detection Network, composed of 114 wideband magnetic direction finders for locating cloud-to-ground lightning flashes, was operated with full coverage of the contiguous United States for the first ...

Abstract: The first significant results of a long detailed lightning study are reported in which the distribution of global midnight lightning is plotted from 60°S to 60°N for the months of September. October and November 1977. ...

Abstract: The first time-resolved spectra of return strokes between the cloud and ground have been obtained. During the summers of 1965 and 1966 twenty-two spectra were obtained at the Institute of Atmospheric Physics, Tuscon, Ariz. ...

Abstract: A model of the lightning return stroke is developed using the experimental data presented in Parts I and II and Gilmore's tables for the composition of dry air in thermodynamic equilibrium. The temperature, electron density, ...

Abstract: A high-speed slitless spectrograph has been used to record photographically with 9 ?s resolution the spectral emissions from five dart leaders. All occurred in the same lightning flash which produced at least 13 return ...

Abstract: An optical multichannel analyzer slit spectrometer coupled to a minicomputer was used to record lightning spectra. This is the first successful application of a slit spectrometer to the study of individual lightning flashes ...
