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]
Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. [1][2][3] These vary depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects, as are thunderstorms ...
A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. [citation needed] It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (), strong winds (tropical cyclone, windstorm), wind transporting some ...
The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw (h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwhara, the ...
Phenomena caused by severe thunderstorms. Excessive Lightning. Derecho. Extreme wind (70 mph or greater) Downpours. Heavy rain. Flood, flash flood, coastal flooding. Hail. High winds – 93 km/h (58 mph) or higher.
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 ...
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 ]
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.
