Do you hear thunder or see lightning first?
If the lightening hit you, then you'd experience both at the same time. However, in general, you'll see lightening first, since that travels at the speed of light, and thunder second, as that travels at the speed of sound.
One way to see this easily in practice is to go to a baseball game or cricket game and sit far away from the action - you will be able to see the batter hit the ball before you hear the sound of the ball hitting his bat.
What type of cloud would result from a fast moving cold front?
A fast moving cold front would likely produce cumulonimbus clouds, which are associated with intense precipitation and weather events such as thunderstorms. These clouds can bring heavy rain, strong winds, lightning, and sometimes hail.
Is lighting ground to sky or from sky to ground?
There is much confusion over the "up" or "down" motion of lightning bolts, but in most cases it is initiated by the flow of negative ions in clouds to a positively charged point at another point (cloud or ground). What is referred to as "lightning" is a luminous path of superheated air caused by repeated current flows from the ground and the air. In certain cloud types, the interaction of ice and water (and possibly the Earth's magnetic field) creates a surplus of negatively charged particles, usually near the bottom of the cloud. Where the ground and objects below have accumulated positive charges, an electric discharge can occur. This is preceded by "step leaders" moving down from the clouds and "positive leaders" moving up from the ground. Where these streams come in contact, the negative ions flow to the ground, followed by a return flow of positive ions. This can occur multiple times in the same lightning strike.
What storm signals is the most dangerous and why?
A storm signal that indicates an extremely dangerous situation is a Category 5 hurricane. These storms have sustained wind speeds of 157 mph or higher, causing catastrophic damage to infrastructure and posing a significant threat to life and property. The combination of intense wind, storm surge, and heavy rainfall make Category 5 hurricanes the most destructive and potentially deadly type of storm.
Cross a lightning storm with a cashew farm?
A lightning storm could potentially damage a cashew farm by causing fires or tree damage due to lightning strikes, impacting the crop yield and farm infrastructure. Proper lightning protection measures such as lightning rods and grounding systems should be implemented to minimize the risk of damage to the farm.
The southwestern US, particularly areas like Southern California and Arizona, is most likely to experience a persistent subsidence inversion during the summer. This is due to the dry desert climate and topography that can trap warm air near the surface and prevent vertical mixing of air masses.
The beat frequency would be 6 Hz, which is the difference between the two overlapping frequencies (256 Hz - 250 Hz). This is the rate at which the intensity of the sound will oscillate, creating a pulsating effect.
True or false cumulonimbious clouds may produce both thunderstorms and hurricanes?
True. Cumulonimbus clouds are associated with thunderstorms, which can produce strong winds, heavy rain, lightning, and thunder. In rare cases, cumulonimbus clouds can also be involved in the formation of hurricanes, which are large, powerful tropical storms characterized by low pressure systems and rotating winds.
Do scientists have devices to minimise the impact on lightning?
Lightning rods have been used on barns and the older, taller houses for a good long time. They are still used on taller structures. There are now devices to short lightning-induced current to ground on communication wires entering a house or other structure.
New,improved grounding systems have been devised in the last 5 years.
By the way, lightning rods are meant to continually drain off the static electricity in the air that, if it built up, could become a lightning bolt. Radio towers have the same beneficial effect.
What process produces precipitation in warm clouds?
The process that produces precipitation in warm clouds is called coalescence. This occurs when water droplets collide and combine to form larger droplets. Once these droplets become heavy enough, they fall as precipitation.
What is Heavy rain showers with lightning?
Heavy rain showers with lightning occur when there is a significant amount of rainfall along with the presence of lightning strikes. This type of weather can be intense and may pose hazards such as flash flooding, strong winds, and the risk of lightning strikes. It is important to take precautions during heavy rain showers with lightning to ensure safety.
Does thunder travel faster in a storm during winter or summer?
Sound travels faster in higher temperatures because in higher temperatures the molecules collide more often. Thus, as the temperature of the medium decrease, the speed of sound decreases. So in the summer.
What storm comes after a thunder storm?
A thunderstorm followed by a period of heavy rain and strong winds may be followed by a possible hailstorm or tornado depending on the severity of the weather conditions.
How are thunderstorms different from rain showers?
Thunderstorms are more intense than rain showers, with the potential for lightning, thunder, strong winds, and sometimes hail. Thunderstorms are often associated with convective activity and can lead to heavy rainfall and flash flooding. Rain showers, on the other hand, are typically lighter and shorter in duration, lacking the intensity and dynamics of a thunderstorm.
The sound emitted by bats has a wavelength of 3.8 mm What is the sound's frequency in air?
To find the frequency, we can use the equation: speed = frequency x wavelength. The speed of sound is approximately 343 m/s in air. So, the frequency of the bat's sound wave would be (343 m/s) / (3.8 mm = 0.0038 m) = 90,263 Hz.
What is the primary purpose of persuasive advertising?
The primary purpose of persuasive advertising is to influence consumer attitudes and behavior towards a product or service. It aims to create a desire for the product, persuade consumers to make a purchase, and ultimately drive sales for the advertiser.
Is ball lightning killing people?
There have been very few documented cases of ball lightning causing harm to people. Most instances of ball lightning do not result in injury or death, as it is a rare and not well-understood phenomenon.
An air mass classified as cT usually forms over which type of earth surface?
An air mass classified as cT usually forms over hot and dry desert or semi-arid regions, such as in the southwestern United States or northern Mexico. It derives its characteristics from being a continental (c) air mass and originating from the tropics (T).
Assuming that the air is dry and room temperature is 20 degrees celcius then the spped of sound is 343m/s.
The frequency of the sound will be 185.4054Hz
Is the greatest amount of gas in the air oxygen?
No it isn't. It is Nitrogen, which makes up 70% of the air we breathe.
What happens when lightning hit earth?
When lightning strikes the Earth, it occurs to discharge the built-up electrical energy in the atmosphere. It can cause damage by starting fires, damaging structures, injuring living beings, or even triggering power outages due to the sudden surge of electricity. Lightning can also lead to the formation of fulgurites, which are natural hollow glass tubes formed in sand or soil when lightning strikes.
What is happening in the air that makes thunderstorms occur?
Thunderstorms occur when air masses collide the most well known is the cool dry air meeting up with the warm humid air. The cool dry air makes the warm humid air particles rise into the atmosphere then it condenses those air particles into clouds. Those clouds then build and build until they get saturated and the water droplets become heavy enough to fall as rain at the same time the air inside the thunderstorms gains energy and all the air particles moving around and bouncing off of each other create energy. Then you get negative and positive air parcels when those air parcels eventually cause lightning. The lightning heats up other air particles then causes them to bounce off other air particles which creates the thunder that you hear.
How do you tell when a thunderstorm is at its Mature stage?
A thunderstorm is at its mature stage when heavy precipitation, strong winds, and lightning are occurring. This stage marks the height of the storm's strength and is often when severe weather, such as hail or tornadoes, may occur.
During which stage of a thunderstorm does rain begin to fall?
The stage of a thunderstorm that rain begins to fall is when the clouds begin to turn black and during and after the lightning strikes.
Which sunglasses have the lightning bolt logo?
The sunglasses with the lightning bolt logo are typically from the brand Ray-Ban. The lightning bolt logo is located on the lenses to indicate the authenticity of the sunglasses.
