Upward Lightning Strikes explores the fascinating and often misunderstood phenomenon of upward lightning, where electrical discharges originate from the ground, often from tall structures like wind turbines and skyscrapers, challenging conventional understanding of lightning behavior. This book addresses critical knowledge gaps in lightning protection and risk assessment, especially as infrastructure grows taller. It highlights how understanding upward lightning is essential for designing effective protective measures and mitigating potential damage, particularly since it poses unique challenges compared to traditional cloud-to-ground lightning.
The book begins by establishing a foundation in atmospheric electricity and then transitions to the specifics of upward lightning initiation mechanisms, focusing on the role of tall structures and atmospheric conditions. It examines detection and measurement techniques, like lightning location systems, emphasizing the importance of lightning research networks. This specialized examination of upward lightning provides an in-depth analysis, distinguishing it from general texts on lightning and offering specific engineering considerations.
Finally, the book delves into the engineering implications of upward lightning, providing practical guidance for designing lightning protection systems and developing risk assessment models. Each chapter builds upon the previous one, culminating in a comprehensive resource for engineers and researchers. It draws from field observations, laboratory experiments, and numerical simulations, connecting to meteorology, materials science, and risk management for a holistic approach.
