The result is the nearly daily development of clouds that produce thunderstorms. For example, "Lightning Alley"—an area from Tampa to Orlando—experiences an extremely high density of lightning strikes. As of 2007, there were as many as 50 strikes per square mile (about 20 per km 2) per year.
Thunderstorms which show radar returns above 14 kilometres (8.7 mi) in height are associated with storms which have more than ten lightning flashes per minute. There is also a correlation between the total lightning rate and the size of the thunderstorm, its updraft velocity, and amount of graupel over land.
Single-cell thunderstorms form in environments of low vertical wind shear and last only 20–30 minutes. Organized thunderstorms and thunderstorm clusters/lines can have longer life cycles as they form in environments of significant vertical wind shear, normally greater than 25 knots (13 m/s) in the lowest 6 kilometres (3.7 mi) of the ...
Storm identification/tracking: Some thunderstorms, identified by IC detection and observation, make no CG flashes and would not be detected with a CG sensing system. IC flashes also are many times as frequent [4]: 192 as CG so provide a more robust signal. The relative high density (number per unit area) of IC flashes allows convective cells to ...
The first week of September is usually one of the busiest times of the year for tropical storms and hurricanes, but there is an eerie silence across the Atlantic Ocean. AccuWeather adjusted its ...
According to the CDC there are about 6,000 lightning strikes per minute, or more than 8 million strikes every day. [11] As of 2008 there were about 240,000 "lightning strikes incidents" around the world each year. [12] According to National Geographic in 2009, about 2,000 people were killed annually worldwide by lightning. [13]

Lightning is a natural phenomenon, more specifically an atmospheric electrical phenomenon. It consists of electrostatic discharges occuring through the atmosphere between two electrically charged regions, either both existing within the atmosphere or one within the atmosphere and one on the ground, with these regions then becoming temporarily partially or wholly electrically neutralized.
