At the same time, the graupel, which is considerably larger and denser, tends to fall or be suspended in the rising air. The updraft carries the super-cooled cloud droplets and very small ice crystals upward. In that area, the combination of temperature and rapid upward air movement produces a mixture of super-cooled cloud droplets (small water droplets below freezing), small ice crystals, and graupel (soft hail). The main charging area in a thunderstorm occurs in the central part of the storm where air is moving upward rapidly (updraft) and temperatures range from −15 to −25 ☌ (5 to −13 ☏) see Figure 1. Uncharged, colliding water-drops can become charged because of charge transfer between them (as aqueous ions) in an electric field as would exist in a thunder cloud. Electrification can be by the triboelectric effect as a result of ion transfer between colliding bodies. The details of the charging process are still being studied by scientists, but there is general agreement on some of the basic concepts of thunderstorm electrification.

6.2 Cloud to cloud (CC) and intra-cloud (IC).The first surviving photograph is from 1882, by William Nicholson Jennings, a photographer who spent half his life capturing pictures of lightning and proving its diversity. The first known photograph of lightning is from 1847, by Thomas Martin Easterly. The fear of lightning is called astraphobia. At all times people have been fascinated by the sight and difference of lightning.
Idiomatic expressions derived from lightning, such as the English expression "bolt from the blue", are common across languages. Humans have deified lightning for millennia. Many other observational variants are recognized, including " heat lightning", which can be seen from a great distance but not heard dry lightning, which can cause forest fires and ball lightning, which is rarely observed scientifically. The three main kinds of lightning are distinguished by where they occur: either inside a single thundercloud (Intra-Cloud), between two different clouds (Cloud-to-Cloud), or between a cloud and the ground (Cloud-to-Ground). Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation. Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions, both in the atmosphere or with one on the ground, temporarily neutralize themselves, causing the instantaneous release of an average of one gigajoule of energy. That means if your body is the best conductor in the vicinity, it'll travel through you too." He adds: "When you are wet, the natural resistance your body has to lightning is slashed in half.For the current year’s list of notable lightning strikes, see Lightning strikes of 2022. Plumbing expert Ray Brosnan previously told Best Life that "if lightning strikes, the electrical current will follow the path it finds with the least resistance all the way down to the ground. Since the pump, lights, and other facilities have power lines linked to the plumbing, a hit to any part of a pool complex can affect all of it," Holle says. Power lines, telephone lines, and plumbing around the pool "are usually unsafe places during a thunderstorm because the current from a lightning strike will travel easily through the standing water, showers, and other plumbing. Ron Holle, research meteorologist at NOAA National Severe Storms Laboratory, explained to USA Today that while swimming pools are small and not likely to be directly hit by lightning, "the area affecting a pool is quite large." You are a likely conduit for electricity in the pool.
