The charge can also move up you, causing your hair to stand on end! This is natures final way of warning you that lightning can strike near you very soon. Positively charged ice crystals rise to the top of the thunderstorm and negatively charged ice particles and hailstones drop to the middle and lower parts of the storm.Īs the differences in charges continue to increase, positive charges rise up taller objects such as trees, houses and telephone poles. Strong rising and sinking motions within the cloud are important too, as they enhance collisions among cloud particles causing a separation of electrical charges. Those storms that fail to produce large numbers of ice crystals may also fail to produce a lot of lightning. The formation of ice in a cloud is an important element in the development of lightning. The clouds at the high levels of the thunderstorm are made of ice crystals. It is estimated that the earth is struck by 100 lightning bolts every second. see an average of 25 million strokes of lightning each year, from some 100,000 storms. At any moment, there are as many as 1,800 thunderstorms in progress somewhere on earth and each is producing deadly lightning. Although meteorologists understand the cloud conditions necessary to produce it, lightning cannot be forecasted. Lightning has fascinated and excited humans for as long as they have watched the skies.
