Purple lightning is an uncommon meteorological phenomenon that has been described as a bright purplish-white light, usually accompanied by a loud clap of thunder. While the exact cause of purple lightning remains a mystery, there are several theories that have been proposed. In this article, we will explore the possible causes of this mysterious phenomenon.
What Is Purple Lightning?
Purple lightning is a rare form of lightning that appears as an intense purplish-white light accompanied by a loud clap of thunder. It is usually seen during storms and can last for a few seconds. This type of lightning has been reported in many parts of the world, most notably in the United States, Canada, Australia, and New Zealand.
What Causes Purple Lightning?
The exact cause of purple lightning is still unknown. However, there are several theories that have been proposed to explain this phenomenon. One of the most popular theories is the ice-crystal theory, which suggests that the intense purplish-white light is caused by the refraction of light through ice crystals.
Another theory suggests that the intense purplish-white light is caused by a combination of the high electric fields of the thunderstorm and the high concentrations of nitrogen oxides in the atmosphere. Nitrogen oxides are common pollutants in the atmosphere and can be produced by burning fossil fuels. The combination of these two elements can create a bright purplish-white light.
Finally, some scientists believe that purple lightning is caused by a combination of the high electric fields of the thunderstorm and the high concentrations of ferric oxide particles in the atmosphere. These particles are created by volcanic eruptions and can be found in the upper atmosphere.
Is Purple Lightning Dangerous?
Purple lightning is not necessarily dangerous, although it can be very intense. As with all lightning, it is best to take safety precautions when it is observed. It is recommended to stay indoors during storms, away from windows and other areas that may be exposed to the lightning.
Where Is Purple Lightning Most Commonly Observed?
Purple lightning is most commonly observed in areas with high levels of atmospheric pollutants, such as urban areas. It is also more commonly seen during the summer months, when temperatures are higher and there is more moisture in the atmosphere.
What Is the Difference Between Purple Lightning and Other Forms of Lightning?
The main difference between purple lightning and other forms of lightning is the intensity of the light. Purple lightning is much brighter than other forms of lightning and is usually accompanied by a loud clap of thunder. It is also more difficult to observe than other forms of lightning, as it is often hidden by clouds.
Is Purple Lightning Rare?
Purple lightning is rare, but it is not unheard of. It can be seen in many parts of the world, but it is most commonly observed in areas with high levels of atmospheric pollution.
