3. The Catatumbo Lightning: Nature’s Eternal Storm
The Catatumbo lightning is a natural beauty hidden in the middle of Venezuela that has perplexed experts and delighted onlookers for ages. Over the mouth of the Catatumbo River, where it drains into Lake Maracaibo, this ongoing thunderstorm strikes. With lightning strikes occurring up to 280 times per hour, for up to 10 hours a day, for over half the year, this phenomena is very amazing in regularity and intensity. The high concentration of methane in the vicinity influences the colour of the electrical discharge by which the lightning is distinguished blue. Local tales have the Catatumbo lightning as a heavenly guardian directing ships and repelling attackers. Actually, this natural lighthouse was quite important in Venezuelan history since it helped to stop multiple colonial invasion efforts. Apart from being a distinctive tourist attraction, the Catatumbo lightning today offers useful information for climate researchers investigating atmospheric electricity and its influence on world temperature trends.
4. The Mysterious Blue Jets of the Upper Atmosphere
Blue jets are an uncommon and poorly known type of lightning occurring high above the clouds in the rarefied air of the upper stratosphere. Rising from the summits of thunderclouds, these brief, cone-shaped flashes of blue light travel distances of up to 50 kilometres in a fraction of a second. Originally observed by researchers in 1989, blue jets have attracted great attention and conjecture ever since. Blue jets flow from the cloud tops towards the ionosphere unlike ordinary lightning, which passes between clouds or from clouds to the ground. Molecular nitrogen emissions in the rarefied air of the upper atmosphere produce its unusual blue hue. Still up for discussion among atmospheric scientists is the precise mechanism behind blue jets. Some ideas propose they might be part of the global electrical circuit, balancing the electrical charge between the ionosphere and the ground. These elusive blue flashes remind us of how much we still have to discover about the intricate electrical events taking on in the atmosphere of our planet as long as research is under progress.
