Changing Weather Patterns and Lightning Activity

Climate change has been linked to more extreme weather conditions, including increased temperatures, altered precipitation patterns, and more volatile atmospheric conditions, all of which contribute to a higher frequency and intensity of lightning strikes.

Increased Lightning Frequency

Studies have shown that for every 1°C increase in global temperature, the frequency of lightning strikes can increase by approximately 12%. This heightened activity presents a growing challenge for existing lightning protection systems.

Intensified Lightning Intensity

Not only is lightning becoming more frequent, but it is also exhibiting greater intensity, with stronger electrical discharges. This trend necessitates robust protection systems capable of withstanding more severe lightning events.

Adapting Protection Strategies

The evolving nature of lightning due to climate change requires a dynamic approach to lightning protection, emphasizing adaptability and resilience.
