Biography/History:

Vlad Mazur has been a physicist at the National Oceanic and Atmospheric Administration/National Severe Storms Laboratory in Oklahoma since 1984. His research interests include lightning physics, lightning-aircraft interaction, computer simulation of lightning processes, interaction of lightning with ground structures, and lightning protection and its physical aspects. He was a pioneer of high-speed photography of lightning in the early 1990s.

Summary:

Principles of Lightning Physics presents and discusses the most up-to-date physical concepts that govern many lightning events in nature, including lightning interactions with man-made structures, at a level suitable for researchers, advanced students and well-educated lightning enthusiasts. The author's approach to understanding lightning--to seek out, and show what is common to all lightning flashes--is illustrated by an analysis of each type of lightning and the multitude of lightning-related features. The book examines the work that has gone into the development of new physical concepts, and provides critical evaluations of the existing understanding of the physics of lightning and the lexicon of terms and definitions presently used in lightning research.
