Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type.
See media help. A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning [1] and its acoustic effect on the Earth's atmosphere, known as thunder. [2] Relatively weak thunderstorms are sometimes called thundershowers. [3]
A supercell is a thunderstorm characterized by the presence of a mesocyclone, a deep, persistently rotating updraft. [1] Due to this, these storms are sometimes referred to as rotating thunderstorms. [2] Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common ...
Cyclogenesis is an umbrella term for at least three different processes, all of which result in the development of some sort of cyclone, and at any size from the microscale to the synoptic scale. Tropical cyclones form due to latent heat driven by significant thunderstorm activity, developing a warm core.
The distribution of lightning, or the incidence of individual strikes, in any particular place is highly dependent on its location, climate, and time of year. Lightning does have an underlying spatial distribution. High quality lightning data has only recently become available, but the data indicates that lightning occurs on average 44 ± 5 ...
A person who was affected by a nearby lightning strike. Note the slight branching redness traveling up the victim's leg from the effects of the current. Common injuries caused by lightning include: muscle pains, broken bones, cardiac arrest, confusion, hearing loss, seizures, burns, behavioral changes, and ocular cataracts.
Effects of tropical cyclones. Percentages of hurricane deaths in the United States from 1970 to 1999. The effects of tropical cyclones include heavy rain, strong wind, large storm surges near landfall, and tornadoes. The destruction from a tropical cyclone, such as a hurricane or tropical storm, depends mainly on its intensity, its size, and ...
