Every Hour 760 Thunderstorms Occur at the Earth

According to a scientific estimate, every hour 760 thunderstorms occur at the earth. The figure, unveiled at the European Geosciences Union meeting in Vienna, is substantially lower than numbers that have been used for nearly a century. Scientists say the new research uses a global network of monitoring stations that detect the electromagnetic pulses produced by major bolts of lightning. It confirms that thunderstorms are mainly a tropical phenomenon - and the Congo basin is the global hotspot. Thunderstorms also track the passage of sunlight across the world, with sunny conditions producing greater convection in the air. The first attempt to estimate thunderstorm numbers is thought to have been made by CEP Brooks in 1925. At that time, it was customary for weather stations to note days when thunderstorms occurred nearby.
