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.
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 ...
No thunderstorms: 2 Isolated thunderstorms. Lightning is very infrequent, 1–5 cloud-to-ground strikes in a five-minute period. 3 Widely scattered thunderstorms. Lightning is infrequent, 6–10 cloud-to-ground strikes in a five-minute period. 4 Scattered thunderstorms. Lightning is frequent, 11–15 cloud-to-ground strikes in a 5-minute period. 5
Ohio has averaged 460,074 cloud-to-ground lightning strikes per year from 1997 through 2012, according to the National Weather Service. ... No place outdoors is safe when thunderstorms are in the ...
While the extent of severe thunderstorms in the East on Memorial Day may be limited to parts of the region, the strongest storms still carry some risk of tornadoes.
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 seen in the sky over the University of Kansas in Lawrence, Kansas, Thursday, March 26, 2020. Strong winds and hail are forecast for the area. (AP Photo/Orlin Wagner) After nearly six ...
Electrification can be by the triboelectric effect leading to electron or ion transfer between colliding bodies. The main charging area in a thunderstorm occurs in the central part of the storm where air is moving upward rapidly (updraft) and temperatures range from −15 to −25 °C (5 to −13 °F); see Figure 1.
