Thunder is the sound caused by and after lightning. [ 1 ] [ 2 ] [ 3 ] Depending upon the distance from and nature of the lightning, it can range from a long, low rumble to a sudden, loud crack. The sudden increase in temperature and hence pressure caused by the lightning produces rapid expansion of the air in the path of a lightning bolt . [ 4 ]
An observer can approximate the distance to the strike by timing the interval between the visible lightning and the audible thunder it generates. A lightning flash preceding its thunder by one second would be approximately 343 m (0.213 miles) away; thus a delay of three seconds would indicate a distance of about 1 km (0.62 miles); while a flash ...
A return stroke, cloud-to-ground lightning strike during a thunderstorm. Cloud-to-ground lightning frequently occurs within the phenomena of thunderstorms and have numerous hazards towards landscapes and populations. One of the more significant hazards lightning can pose is the wildfires they are capable of igniting. [54]
Thunder and lightning are much more common in warm, summer months because of convection, the upward motion of air that helps produce thunderstorms. Because convection is rare in winter ...
A thunderstorm that produces thunder and lightning but in which most or all of its precipitation evaporates before reaching the ground. Dry thunderstorms occur necessarily in dry conditions, and their lightning strikes, sometimes referred to as dry lightning, are a major cause of wildfires. dual polarization weather radar dusk dust devil dust storm
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. A method to determine the distance ...
Sympathetic lightning is the tendency of lightning to be loosely coordinated across long distances. Discharges can appear in clusters when viewed from space. [22] [23] [24] [clarification needed] Upward lightning or ground-to-cloud lightning is a lightning flash which originates from the top of a grounded object and propagates upward from this ...
Thunder and Lightning [293] [294] Chuck Muncie and Tony Galbreath: 1976–1980 New Orleans Saints dynamic running back duo known as "Thunder and Lightning". The nickname is credited to former Saints Head Coach Hank Stram. Tommy [295] E. F. Hughitt: The origin of this early NFL star's nickname remains unknown.
