Lightning represents a natural phenomenon of substantial interest. Due to its complex nature, research continues in many countries and reveals amazing results. Lightning is actively observed because of its relevance to Earth climate and air composition in addition to the classical aspects of related human fatalities and damage to forests, buildings, power lines, aircraft, structures and electronic devices. In this volume, the most important contemporary questions on lightning are addressed and analyzed under many experimental and theoretical aspects. Lightning detection techniques using ground-based and space-borne methods are described, along with network engineering and statistical analysis. Contributions detail research on atmospheric electricity, cloud physics, lightning physics, modeling of electrical storms and middle atmospheric events. Special phenomena such as triggered lightning and sprite observations are examined. Lightning-induced nitrogen oxides and their effects on atmospheric chemistry and climate are discussed. Each topic is presented by international experts in the field. Topics include: * air chemistry * convective storms * infrasound from lightning * lightning and climate change * lightning and precipitation * lightning and radiation * lightning and supercells * lightning and thunderstorms * lightning detection * lightning from space * lighting protection * lightning return strokes * observations and interpretations * spatial distribution and frequency * triggered lightning * weather extremes

The objects of the American Meteorological Society are "the development and dissemination of knowledge of meteorology in all its phases and applications, and the advancement of its professional ideals." The organization of the Society took place in affiliation with the American Association for the Advancement of Science at Saint Louis, Missouri, December 29, 1919, and its incorporation, at Washington, D. C., January 21, 1920. The work of the Society is carried on by the Bulletin, the Journal, and Meteorological Monographs, by papers and discussions at meetings of the Society, through the offices of the Secretary and the Executive Secretary, and by correspondence. All of the Americas are represented in the membership of the Society as well as many foreign countries.

A lightning summary was developed for a 100x100 kilometer area centered at the NASA Kennedy Space Center. Spatial and temporal patterns, and first stroke peak currents were analyzed from 1986-1995. Three thunderstorms were chosen due to their proximity to the Kennedy Space Center (KSC) and examined for their end of storm characteristics. Radar echoes at the -10 deg C and -20 deg C temperature heights were associated with cloud to ground (CG) lightning strike locations from the National Lightning Detection Network. Electric fields were also examined during the same time frame for any correlations. A pattern was observed for the spatial distribution of CG lightning. An inland maximum in ground flash density was observed during the summer months for both negative and positive flashes. The summer months had the lowest percentage positive flashes (2.5%) while the maximum value occurred during the winter (11.4%). Although thunderstorms can occur at any time during the day, the diurnal distribution of lightning flashes showed that the afternoon (2000 UTC) was the time of maximum lightning activity. From a time history of radar echoes, it was found that a 45 dBZ echo, last detected at the -10 deg C temperature height, may be a good indicator of the end of lightning activity. The observed lag times between this lightning termination signature and the end of all CG lightning flashes was 30 min for all three thunderstorms.
