Weaker thunderstorms are steered by winds closer to the Earth's surface than stronger thunderstorms, as the weaker thunderstorms are not as tall. Organized, long-lived thunderstorm cells and complexes move at a right angle to the direction of the vertical wind shear vector. If the gust front, or leading edge of the outflow boundary, races ahead ...
An air-mass thunderstorm, also called an "ordinary", [1] "single cell", "isolated" or "garden variety" thunderstorm, [2] is a thunderstorm that is generally weak and usually not severe. These storms form in environments where at least some amount of Convective Available Potential Energy (CAPE) is present, but with very low levels of wind shear ...
Rumbles are less loud, last for longer (up to more than 30 seconds), and are of low pitch. [16] Inversion thunder results when lightning strikes occur between the cloud and ground during a temperature inversion. The resulting thunder sounds have significantly greater acoustic energy than those produced from the same distance in non-inversion ...
After a few days break, bitter Arctic cold will overspread much of the north-central U.S. Wednesday, while the East Coast sees heavy rain and thunderstorms from a potent storm.
Met Office predicts a mix of sunny spells and showers across the country
Individual thunderstorm updrafts and downdrafts along the line can become strong, producing large hail and strong outflow of straight-line winds ahead of system. Tornadoes are only occasionally reported. [2] In certain conditions, squall line can extend on a very long line, moving extremely rapidly, and become a derecho.
California getting much needed break from storms. How long will it last? Alex Sosnowski. January 18, 2023 at 1:17 PM. 1 / 7. California getting much needed break from storms. How long will it last?
A squall line over 1,000 mi (1,600 km) long across the Gulf of Mexico and the Eastern U.S (radar coverage is from ground radars, so middle image does not cover the portion over the Gulf). The rightmost image is a couple of hours after the other two, showing the strongest portion of the line as it passes through Florida, Georgia, and South Carolina.
