Science of Lightning: Lightning isanatmosphericelectrostatic discharge (spark) accompanied bythunder,whichtypically occurs during thunderstorms,and sometimesduringvolcaniceruptions or dust storms. From this dischargeofatmosphericelectricity, a leader of a bolt of lightning cantravelat speedsof 220,000 km/h (140,000 mph), and canreachtemperaturesapproaching 30,000 °C (54,000 °F), hot enough tofusesilica sandinto glass channels known as fulgurites whicharenormally hollowand can extend some distance into the ground.Thereare some 16million lightning storms in the world everyyear.Lightning causesionisation in the air through which ittravels,leading to theformation of nitric oxide and ultimately,nitricacid, of benefitto plant life below. Lightning can alsooccurwithin the ash cloudsfrom volcanic eruptions, or can be causedbyviolent forest fireswhich generate sufficient dust to createastatic charge. Howlightning initially forms is still a matterofdebate: Scientistshave studied root causes ranging fromatmosphericperturbations(wind, humidity, friction, and atmosphericpressure)to the impactof solar wind and accumulation of chargedsolarparticles. Iceinside a cloud is thought to be a key elementinlightningdevelopment, and may cause a forcible separationofpositive andnegative charges within the cloud, thus assistinginthe formationof lightning. The irrational fear of lightning(andthunder) isastraphobia. The study or science of lightningiscalledfulminology, and someone who studies lightning is referredtoas afulminologist.
