13 Unexpected Benefits of Lightning: The 7th Will Astonish Scientists

11. Atmospheric Pressure Regulation

Maintaining Earth's temperature stability and weather patterns depends on the surprising and important control of air pressure provided by lightning. Usually disregarded in talks on atmospheric dynamics, this process shows the complex equilibrium of the systems on Earth. Lighting strikes quickly heat the air in its path to temperatures hotter than the sun's surface. The air expands explosively from this great warmth, producing a shock wave we hear as thunder. Still, the impacts transcend the audible boom. During a lightning strike, the fast heating and subsequent cooling of air masses produce notable localised variations in air pressure. With millions of lightning strikes occurring worldwide every day, these large-scale pressure oscillations help to mix air generally in the atmosphere. Heat and moisture must be distributed around the world by this mixing; the fast heating and consequent cooling of air masses during a lightning strike produce notable localised changes in air pressure. With millions of lightning strikes occurring worldwide every day, these large-scale pressure variations help to mix the air generally in the atmosphere. Distribution of heat and moisture around the world depends on this mixing. Maintaining a constant temperature and avoiding extreme weather occurrences depend on the process helping to equalise temperature variations among several layers of the atmosphere. Moreover, the electrical character of lightning contributes to the global electrical circuit, therefore impacting the ionosphere and maybe influencing more general atmospheric dynamics. Lightning strikes' generated ions can function as nuclei for water droplets to form, therefore affecting cloud formation and precipitation patterns. A feedback loop produced by this link between lightning and cloud development helps to control atmospheric pressure. Lightning serves to minimise the accumulation of significant pressure differentials that might result in more catastrophic weather events by affecting both local and worldwide air motions. The complicated interaction between electrical, thermal, and mechanical processes in Earth's atmosphere is shown by this regulating effect of lightning on atmospheric pressure, therefore illustrating how an apparently destructive force really helps to maintain the planet's general climatic stability.
