7. Catatumbo Lightning
Over the Catatumbo River in Venezuela, a singular and recurring lightning phenomena known as catatumbo lightning strikes. Visible for several kilometres and with great regularity and intensity, Catatumbo Lightning can generate up to 280 lightning strikes every hour. From May to November, during the rainy season, this phenomena is most active and can last up to ten hours every night. Though the precise reason of Catatumbo Lightning is unknown, it is thought to be connected to the particular terrain and meteorological circumstances of the area. The Andes Mountains together with the confluence of warm and cold air masses produce perfect circumstances for the development of thunderstorms and strong electrical activity. A major player in the global atmospheric electrical circuit and essential for the synthesis of ozone in the Earth’s atmosphere is catatumbo lightning. For the area, the phenomena is also very significant ecologically and culturally since it offers a natural show that local people have cherished for millennia. By providing insightful analysis of the intricate relationships of geography, weather, and atmospheric electricity, Catatumbo Lightning helps us to better grasp lightning and its function in the Earth’s climate system.
8. Positive Lightning
Unlike bottom-oriented lightning, positive lightning is a strong and rather rare kind of lightning that starts from the top of a thunderstorm cloud. Positive lightning contains a positive charge unlike the more often occurring negative lightning, which charges the ground. Because of its high voltage and long duration, which can cause more serious damage than in negative lightning strikes, this kind of lightning is very hazardous. Often known as a “bolt from the blue,” positive lightning can strike many kilometres distant from the main thunderstorm and unexpectedly catch people and buildings. Although the exact processes behind positive lightning are unknown, it is thought to be connected to the top sections of major thunderstorm systems and may be involved in the starting of other kinds of lightning activity. Understanding the whole spectrum of lightning behaviour and enhancing safety measures for infrastructure and people depends on an awareness of positive lightning. Better predictive models and a better knowledge of the electrical dynamics inside thunderstorms can result from an analysis of the factors causing the generation of positive lightning.
