But much of what we think we know about lightning is fiction. Here are some common myths, along with the facts that will keep you and your loved ones safe in a storm. At any given time on our planet Earth, there are 1, thunderstorms in progress—and with them comes lightning. Property damage from lightning is covered by standard homeowners insurance for your home, and the comprehensive portion of an auto policy for your car—but bodily harm from lightning isn't easily remedied. During a thunderstorm, it's best to take shelter in a house, other structure or a hard-topped, fully enclosed vehicle.

For reasons not well understood, bidirectional leaders tend to initiate on the tips of the decayed positive leaders in which the negative end attempts to re-ionize the leader network. Based on a Nigerian folk. When it occurs between two separate clouds it is known as thundet lightning .

Thunderstorm , a violent, short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail , and strong, gusty winds. Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere. There the moisture contained in the updraft condenses to form towering cumulonimbus clouds and, eventually, precipitation. Columns of cooled air then sink earthward, striking the ground with strong downdrafts and horizontal winds. At the same time, electrical charges accumulate on cloud particles water droplets and ice. Lightning discharges occur when the accumulated electric charge becomes sufficiently large.
