The flash of a lightning strike and resulting thunder occur at roughly the same time. But light travels 300,000 km/sec, almost a million times the speed of sound. Sound travels at the slower speed of about 340 m/sec (depending on the temperature), so the flash of lightning is seen before thunder is heard.
When a sufficiently large positive lightning strike carries charges to the ground, the cloud top is left with a strongly negative net charge. This can be modeled as a quasi-static electric dipole and for less than 10 milliseconds a strong electric field is generated in the region above the thunderstorm.
Positive lightning is less common than negative lightning and on average makes up less than 5% of all lightning strikes.

When seen from Earth, lightning appears both powerful and majestic, but when viewed from space, it can seem a little ghostly. Astronaut spots 'spooky' lightning on Earth from space Skip to main ...
World map showing frequency of lightning strikes, in flashes per km 2 per year (equal-area projection). Lightning strikes most frequently in the Democratic Republic of the Congo . Combined 1995–2003 data from the Optical Transient Detector and 1998–2003 data from the Lightning Imaging Sensor.
A lightning detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors: ground-based systems using multiple antennas, mobile systems using a direction and a sense antenna in the same location (often aboard an aircraft), and space-based systems.
Nov. 29—This is the time of year for Spotify Wrapped and Apple Music Replay lists. For director Jeremiah Heitman, his list might include the soundtrack to "The Lightning Thief."
A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity.Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations.
