A drop in the incidence of lightning strikes could impact foraboutonto on the frequency of wildfires, especially in tropical regions. It could also lower the incidence of lightning strikes to infrastructure and affect how greenhouse gases in the atmosphere contribute to climate change. Scientists from the Universities of Edinburgh and Leeds and Lancaster University used a newly devised method to calculate the likely incidence of lightning flashes from storm clouds. UnlikeUnlessExceptBesides Unlike traditional calculations of lightning flashes at the global scale, which are based on the height of clouds, their approach takes into account the movement of tiny ice particles that form and move within clouds. Electrical charges build uponupaboveoff up in these ice particles, and in cold water droplets and soft hail formed inside clouds.
