The previous review of U.S. lightning research for the IUGG covered the period 1971–1975 and was published by Uman et al. (1975). Although the present review is intended to cover the research of the last four years, 1979–1982, we will survey the total seven year period, 1976–1982, since the previous review. References to 82 articles were included in the 1971–1975 review, an average of 16 to 17 papers per year. Interestingly enough, the yearly average for 1976–1982 is 18, a value almost identical to the previous period. Many of these recent articles describe research performed as part of the Thunderstorm Research International Program (TRIP) hosted by the NASA Kennedy Space Center (KSC), Florida in 1976–1978 and by the New Mexico Institute of Mining and Technology in Socorro, New Mexico in 1979–1982.
