Abstract : The report surveys the characteristics of the radio noise due to lightning. Many sources of information are used, and several of the problems involved in intercomparison of these data are discussed. Knowledge of the electrical behavior for a typical thunderstorm is examined. It is demonstrated that the structure of the noise generated by a storm can be determined from such parameters as flashing rate, proportion of discharges to earth, etc., coupled with information on the pulse emissions due to an individual flash. This procedure can be extended to all global thunderstorms, and estimates are given of the activity associated with each of the major world thunderstorm centers. (Author)
