Hard X ray and neutron emissions measured in low-Earth orbit are surveyed to develop a global overview of lightning-related energetic-electron precipitation and acceleration processes. Comparison of geographic intensity maps shows the dominance of enhanced hard X ray intensities measured when the satellite was above the continental United States and above the southern Indian Ocean between Madagascar and Australia. This emission is most enhanced during the northern summer months. Lesser although significant enhancements are seen between the Middle East and the Tibetan Plateau, a stretch of ocean off the east Asian coast between the Philippines and Korea, a stretch of equatorial Africa from the Ivory Coast to Mozambique, a region of the eastern equatorial Pacific just west of Columbia, and a patch of the Indian Ocean stretching between the southern tip of India and Indonesia. Although emissions from many of these regions are generally enhanced during the northern summer and fall seasons, none show any regularity relative to local time of day. Many but not all of these enhancements support natural interpretations in terms of lightning-induced energetic-electron precipitation from the terrestrial trapped radiation belts. Electron scattering induced by radio waves from VLF transmitters most likely contributes to this precipitation. ¿ American Geophysical Union 1996
