How do you describe a thunderstorm?
thunderstorm, a violent short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds. Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere.
What defines an air mass storm?
An air-mass thunderstorm, also called an “ordinary”, “single cell”, or “garden variety” thunderstorm, is a thunderstorm that is generally weak and usually not severe. Like all thunderstorms, the mean-layered wind field the storms form within determine motion.
What is frontal thunderstorm?
The movements of air masses that cause thunderstorms are mainly found at cold fronts. The denser cold air pushes under the warmer air of the warm front, lifting it up. Frontal thunderstorms occur over larger areas than thermal thunderstorms, but they are less violent.
How do mountain thunderstorms develop?
Mountains generate such storms through a variety of processes. Most basic, again, is simple convection: Ground heated by the sun warms the air above it and causes it to ascend, potentially to the level where its water vapor condenses into clouds.
What is the sentence of storm?
Storm sentence example. As soon as the sun appeared in a clear strip of sky beneath the clouds, the wind fell, as if it dared not spoil the beauty of the summer morning after the storm ; drops still continued to fall, but vertically now, and all was still. He’d probably storm out and leave her.
What does thunderstorm mean in weather?
Thunderstorm – A rain-bearing cloud that also produces lightning. All thunderstorms are dangerous. Every thunderstorm produces lightning. Other associated dangers of thunderstorms include tornadoes, strong winds, hail, and flash flooding.
What type of storm is a thunderstorm?
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth’s atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers.
What is a difference between an air mass thunderstorm and a steady state thunderstorm?
A) Air mass thunderstorm downdrafts and precipitation retard and reverse the updrafts. Steady-state thunderstorms are associated with local surface heating.
What are the three stages of a thunderstorm?
Thunderstorms have three stages in their life cycle: The developing stage, the mature stage, and the dissipating stage. The developing stage of a thunderstorm is marked by a cumulus cloud that is being pushed upward by a rising column of air (updraft).
What are the 3 main types of thunderstorms?
There are three types of thunderstorms:
- single-cell (or air mass)
- multicell cluster.
- multicell (or squall line)
- supercell.
What are the conditions of a thunderstorm?
Thunderstorms are small, intense weather systems that make strong winds, heavy rain, lightning, and thunder. Thunderstorms can happen anywhere with two conditions: the air near the Earth’s surface must be warm and moist (with lots of liquid), and the atmosphere must be unstable.
How strong are thunderstorms?
STRONG THUNDERSTORM – A thunderstorm with winds gusting at or over 38 MPH but not as high as 58 MPH. If a thunderstorm has hail less than 3/4″, it must also be classified as a strong thunderstorm.
What is the definition of severe thunderstorm?
SEVERE THUNDERSTORM DEFINITION: A severe thunderstorm as defined by the National Weather Service is a storm with hail = or > than 1″ in diameter or convective wind gusts = or > than 58 mph. Even if a storm is not severe, it still remains a potential killer.
What are the effects of thunderstorms?
Effects of Thunderstorms. Thunderstorms have wide-ranging effects on human life, including electrocution, shock, and even worse, deaths. They normally have a significant effect on the weather over an expansive area, with energy generated at the rate of at least 10,000,000 kilowatt-hours on an average.
