I love to read anything from newspapers, tabloids, comics, books, other religious books that include Holy Bible and Holy Quran. Yesterday my attention was focused on a verse of the Holy Qur'an 24:43 translated in English that says "And He sends down hail from mountains (clouds) in the sky, and He strikes with it whomever He will, and turns it from whomever He wills. The vivid flash of its lightning nearly blinds the sight."
Wikipedia defines Hail as a form of solid precipitation which consists of balls or irregular lumps of ice, that are individually called hail stones. Hail stones on Earth consist mostly of water ice and measure between five millimeters (0.20 in) and 150 millimeters (5.9 in) in diameter, with the larger stones coming from severe thunderstorms.
In 1600 AD, Aristotle's ideas on meteorology explained that thunder is the sound of collision of the dry emanation with the neighboring clouds and lightning is the inflaming and burning of the dry exhalation with a thin and faint fire.
In Meteorology Today - authored by Ahrens - explains that a cloud becomes electrified as hail falls through a region in the cloud of super-cooled droplets and ice crystals. As liquid droplets collide with hailstone, they freeze on contact and release latent heat. This keeps the surface of the hailstone warmer than that of the surrounding ice crystals. When the hailstone comes in contact with an ice crystals, an important phenomenon occurs - electrons flow from the cooler object toward the warmer object.
And because the hailstone becomes negatively charged, the same effect occurs when supercooled droplets come in contact with hailstone and tiny splinters of positively charged ice break off. These lighter positively charged particles are then carried to the upper part of the cloud by updrafts. The hail, left with a negative charge, falls towards the bottom of the cloud, thus the lower part of the cloud becomes negatively charged. These negative charges are then discharged as lightning. And it is concluded that it is the hail the major factor in producing lightning.
In spite of the many sources for ideas to write, it's the Holy Qur'an gives me the idea for this article. Awesome!
