What becomes charged by an electrified cloud?
The ability of a storm cloud’s electric fields to transform air into a conductor makes charge transfer (in the form of a lightning bolt) from the cloud to the ground (or even to other clouds) possible. A lightning bolt begins with the development of a step leader.
Are clouds negatively charged?
The negative charges in the bottom of the cloud have such a high concentration that they force the electrons on the Earth’s surface deep into the ground. Thus, the ground has a strong positive charge and the cloud has a strong negative charge.
Does cloud to cloud lightning make thunder?
We also commonly see lightning strike from cloud to cloud, lightning flashes within the same cloud, and lightning that stretches from a cloud to the air around it. This answers our question: All lightning creates thunder because all lightning is hot enough to create that sonic boom.
What happens when lightning hits a cloud?
There are situations where lightning finds negatively charged particles on the ground level and positive charges in the upper portion of a cloud overcome negative charges in the bottom of a cloud. This is when a positive lightning strike happens. Positive lightning strikes are not as common but are more dangerous.
How are clouds electrified?
Water droplets form in our atmosphere when the air cools to the dewpoint and achieves a relative humidity of 100\%. At this temperature, water vapor condenses (changes from a gas to a liquid) and this process occurs on individual tiny dust or aerosol particles called cloud condensation nuclei.
What is Spider lightning?
Spider lightning refers to long, horizontally traveling flashes often seen on the underside of stratiform clouds. Spider lightning is often linked to +CG flashes.
Why Can’t we Touch clouds?
Although we can see clouds, if you were to try to touch one your hand would go straight through it. This is because the water droplets are very very small, like the water in steam. Although we can’t really touch clouds you could walk through one.
How do you touch clouds and water?
When you go out in it, you feel the water lightly against your face and hands; you have breathed in the cloud as well. As far as touching other types of clouds, you have to raise yourself to the level at which they form, most likely by climbing a hill or mountain.
What happens when water droplets in clouds join together?
Sometimes the water droplets in clouds join together until they make larger droplets, which then fall to the ground as rain. If a cloud has formed especially high up these droplets might fall as snow or hail instead. Clouds can hold a lot of water droplets; some are so large that they contain millions of tons of water!
What would it feel like to be electrocuted by lightning?
Fluorescent light bulbs contain plasma. Your hands would probably tingle as a small amount of electric current passes through you. Lightning is a plasma. You’d feel a giant jolt as an enormous amount of current travels through your body.
