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]
Thunder is the sound caused by 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]
Atmospheric noise is radio noise caused by natural atmospheric processes, primarily lightning discharges in thunderstorms. It is mainly caused by cloud-to-ground flashes as the current is much stronger than that of cloud-to-cloud flashes. [ 2] On a worldwide scale, 3.5 million lightning flashes occur daily.
Thundersnow, also known as a winter thunderstorm or a thundersnow storm, is a thunderstorm in which snow falls as the primary precipitation instead of rain. It is considered a rare phenomenon. [ 1] It typically falls in regions of strong upward motion within the cold sector of an extratropical cyclone. Thermodynamically, it is not different ...
Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions .
However, rounds of thunderstorms are expected to organize along the northern periphery for a multi-day stretch. "A 'rinse and repeat' pattern is in store Drenching, severe storms to rumble over ...
A sprite at the horizon, with lightning below in the troposphere and above the green line of airglow at the upper mesopause and border to space (the bright light above is the Moon). First color image of a sprite, taken from an aircraft. A sprite over Laos, as seen from the International Space Station. Sprites appear as luminous red-orange flashes.
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
