11. Blue Bursts: Explosive Energy in the Mesosphere
Recently discovered, blue bursts are a type of blue lightning occurring in the mesosphere—a layer of the atmosphere above the stratosphere. Blue bursts are some of the most often occurring atmospheric electrical events, unlike ordinary lightning, which is limited to the troposphere and reaches only altitudes of up to 80 kilometres.
Blue bursts are very intense phenomena, unleashing volumes of energy equivalent to tiny nuclear explosions, according recent observations made using specialist satellite instruments. They differ from ordinary lightning and even from other kinds of blue lightning in this great power output.
Blue bursts, according to scientists, could be very important in the global atmospheric electrical circuit and hence affect large-scale climate dynamics and weather patterns. This finding has opened fresh directions of investigation on the interactions between several layers of Earth’s atmosphere and their effects on the general energy balance of our planet.
12. Halo Events: Rings of Mystery
A kind of blue lightning, halo events show up as scattered, ring-shaped lights in the lower ionosphere. Halos are unlike the clear, distinct pathways of typical lightning; they are rather large, circular areas of lighting spanning several tens of km in diameter.
Recent research indicates that strong cloud-to- ground lightning strikes are intimately linked with halo phenomena. These collisions produce a strong electromagnetic pulse that causes the lower ionosphere to briefly but intensely heat, producing the characteristic ring-shaped light.
The possible influence of halo events on radio wave propagation is among the most fascinating feature of them. These events have been found to cause localised disturbances in the ionosphere, therefore influencing navigation systems and long-distance radio communications. This result emphasises the need of knowing upper-atmospheric electrical occurrences for both scientific and pragmatic goals.
