Lightning represents a natural phenomenon of historic interest; due to its complex aspects research continues in many countries and reveals amazing results. One focus of attention relates to the hazards which, though less dangerous than flash floods, cause both a number of human victims every year and increasing damage to forests, buildings, power lines and other structures. In the present volume, the most important current questions on Lightning are described and analysed under many experimental and theoretical aspects, and each topic is presented by experts in the field.
Lightning detection techniques using different methods, network engineering and statistical results are described.Understanding of the various processes during flash occurrence is still a matter of research, such as initiating effects, development and propagation of leaders, and electrical neutralization by means of relatively large currents in discharge channels. In this sense, contributions contain research in atmospheric electricity regarding cloud physics and lightning, lightning physics, modelling of the electricity of storms, and lightning in relation with middle atmospheric events. Special phenomena such as triggered lightning, sprite observations, lightning-related chemical effects in the atmosphere are covered. Finally, severe weather conditions are often related to lightning so that observations and nowcasting are scrutinized.
