A Search for Wave Induced Particle Precipitation from Lightning and Transmitter Sources
Abstract
Wave induced particle precipitation is introduced and examined for whistlers whose sources are within the plasmapause. The possible correlation between lightning strokes that carry positive charge to the ground and the observed 'Trimpi' events is discussed, sudden phase and/or amplitude shifts of a received VLF signal with gradual return to predisturbed values. The thunderstorm charging mechanisms that lead to the observed charge distribution and the advection of the positively charged cirrus anvil away from the body of the thunderstorm are briefly examined. The comparative current strengths and the relative frequency of positive and negative strokes is studied for different types of thunderstorms. The magnetospheric ducting of the lightning generated whistler wave and the interaction with trapped electrons is examined. The detectable effects the precipitating electrons have on the ionosphere is introduced. Included are testing and design of the x-ray detector and balloon launch considerations. The problems encountered during the x-ray detector's balloon flights are examined. The riometer and x-ray detector data analysis methods are mentioned. The results were negative for the data that was analyzed but the limiting factors severely restricted the usable data. Possible experimental methods are mentioned. Theses.
