| Popis: | This paper discusses electrical system parameters that would be consistent with observations of the Thunderstorm Research International Project storm at the Kennedy Space Center on July 11, 1978, described by Nisbet et al. (1990). Three-dimensional electrodynamic modeling of the thundercloud electrification made it possible to estimate the current moments and electrical power generated continuously throughout the evolution of the two cells of the storm. The current moments generated were compared with the current moments transferred by intercloud and cloud-to-ground lightning. It is shown that, for the southern cell, which produced a charge moment of about 8.4 MC m, lightning utilized about 84 percent of the charge moment separated; for the northern cell, which produced about 1.1 MC m, lightning utilized about 60 percent of the charge moment separated. |
