Lightning Strikes More Often in Skies Full of Pollution: Study

Human-induced environmental changes, such as air pollution influence weather patterns in surprising ways according to a recent study. Researchers from James Madison University (JMU) have found a link between increased air pollution and more frequent lightning strikes during thunderstorms. Analyzing data from over 500,000 thunderstorms across Washington, DC, and Kansas City over 12 years, the study reveals that higher concentrations of fine particulate matter (PM2.5 and PM10) in the air correlate with increased lightning activity. Pollutants serve as cloud nuclei, which affect how electrical charges are distributed within storms, leading to more lightning. However, there's a threshold beyond which too many particles can reduce lightning due to decreased storm energy. These findings suggest that urban pollution not only influences storm intensity but also modifies meteorological patterns globally. Source: Oman News Agency
