Planning aid, general<strong>information</strong>Creation of lightning dischargesCreation of lightning discharges: 1 = approx. 6,000 m, approx. −30 °C, 2 = approx. 15,000 m, approx. −70 °CDischarge typesSome 90% of all lightning dischargesbetween a cloud <strong>and</strong> the -ground are negative cloud-earthstrikes. The lightning begins in anegatively charged area of thecloud <strong>and</strong> spreads to the positivelycharged surface of the earth. Additionaldischarges are divided into:• Negative earth-cloud strikes• Positive cloud-earth strikes• Positive earth-cloud strikes.The most common discharges actuallyoccur within a cloud or betweendifferent clouds.Creation of lightning dischargesWhen warm, damp air massesrise, the air humidity condenses<strong>and</strong> ice crystals are formed at -great heights. Storm fronts can occurwhen the clouds exp<strong>and</strong> toheights of up to 15,000 m. Thestrong upwind of up to 100 kilometresper hour causes the lightice crystals to enter the higherarea <strong>and</strong> the sleet particles enterthe lower area.
