Description
Book SynopsisThis book about lightning summarizes the essence of physics and effects of lightning in a non-technical manner and provides an up-to-date description of the phenomenon of lightning in simple language. Starting with the myths related to lightning, the reader is introduced to the mechanism of lightning flashes and their interactions with humans, human-made systems and Earth’s environment. Most of the available books on lightning are written for the experts in the field and there is a need for a book that introduces the undergraduate and beginning post graduate students to the subject of lightning and prepares them for more advanced books meant for the experts. This introductory book, which is based on a series of lectures given to undergraduate and postgraduate students in electrical engineering, is intended to fill this need. Tailored to the needs of university students who plan to study electrical engineering, meteorology, environmental or basic physics, it is also a valuable reference resource for laymen who are interested in knowing more on this phenomenon.
Trade Review“In a clear and digestible manner, it provides detailed information about the physical processes involved in the lightning discharge and discusses the pertinent principles of lightning protection from the perspective of a general reader. … the book is clear and easy to digest, and it enables a student to obtain a solid understanding of the physical processes involved in the lightning discharge.” (Robert C. Moore, Physics Today, June, 2015)
