How does charge build up in a cloud to form lightning? Now, the cloud becomes a thundercloud. Lots of small bits of ice bump into each other as they move around. All these collisions cause a build up of electrical charge. Eventually, the whole cloud fills up with electrical charges. Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud.

- Intracloud lightning is the most common type of lightning. This occurs when there are both positive and negative charges within the same cloud. Usually, the process takes place within the cloud and looks like a bright flash of light which flickers.ost cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below. Cloud-to-ground lightning bolts strike the tall objects, like trees and buildings. These lightning strikes can cause fire and property damage.

A Quick Glance at the Causes and Effects of Thunderstorms Causes of Thunderstorms. ~ Thunderstorms occur when warm, moist air within a rain cloud, rises in large volumes and with increasing velocity. ~ The velocity and volume of warm air within the cloud increases, initiating a warm updraft. This makes the storm cloud more buoyant and it rises upwards.

Lightning: FAQ Once enough charge has been separated in a growing storm, a lightning flash can occur. These normally travel within or between clouds (abbreviated CC) or from cloud to ground (CG). Most storms produce more CC than CG flashes--about six times as many in tropical storms and two times as many in midlatitudes.

Clouds & Rain What Happened: Clouds are formed when water warms up and changes into a gas called water vapor, which rises up into the air. As it rises higher in the sky, the water vapor cools down and turns back into tiny drops of liquid. Inside the jar, some of the warm water evaporated into water vapor.

How lightning works A cloud-to-ground lightning strike starts as a channel of negative charges makes its path towards the ground. This occurrence is known as a stepped leader. The stepped leader continues towards the ground in a series of steps that are each about 50 to 100 metres in length.

- A cloudburst is essentially an extremely heavy downpour that is defined as rainfall rate >=100 mm /hour. Some reasons for occurrence of cloudbursts are: When a cloud encounters a mountain or such physical body in its path causing it to shed its entire moisture-load in a small span of time. In a thunderstorm, air currents carrying huge amounts of water rush upwards. If they cease, the entire amount of water carried by these air currents descends upon a small area.

Cloud physics Cloud condensation nuclei are necessary for cloud droplets formation because of the Kelvin effect, which describes the change in saturation vapor pressure due to a curved surface. At small radii, the amount of supersaturation needed for condensation to occur is so large, that it does not happen naturally.

How do clouds form? Clouds are formed when water droplets contained in the air rise higher into the atmosphere. There they collect, until a cloud is formed. When water evaporates into the air, it hits the dew point temperature and sticks to smoke and dust particle in the air. Next, it condenses to form a cloud.

- Often in galaxies we find clusters of young stars near other young stars. This phenomenon is called supernova induced star formation. The very massive stars form first and explode into supernova. This makes shock waves into the molecular cloud, causing nearby gas to compress and form more stars.nd they occur in clusters, groups of stars that form from the same cloud core. Once a clump has broken free from the other parts of the cloud core, it has its own unique gravity and identity and we call it a protostar. As the protostar forms, loose gas falls into its center.

- 1. Thunderstorms are most  common in the afternoon over land, when daytime heating of the land  by the sun causes the lower part of the troposphere to become  unstable from … higher temperatures and more water vapor in the air.s a result, land heats up faster in the day and cools  down more slowly at night than water does. For this reason, air  over land tends to be warmer in the day an cooler at night than air  over water. + 3 others found this useful.

What are clouds? Clouds form when the air is saturated and cannot hold any more water vapour, this can happen in two ways: 1  The amount of water in the air has increased - for example through evaporation - to the point that the air cannot hold any more water.

Article:               Why does it rain? Print When water becomes warm enough, it evaporates as vapor into the air. When a mass of air quickly cools to its saturation point, the water vapor condenses into clusters of tiny water droplets and frozen water crystals. We call these clusters clouds. Over time, the droplets and crystals that make up a cloud can attract more water to themselves. When water droplets grow heavy enough, gravity pulls them down as raindrops. If the air is cold enough, the ice crystals can remain frozen and grow large enough to fall as snow, sleet, freezing rain or hail. Credits: Answered by: Discovery Channel

- Thunderstorms Thunderstorms form when moist, unstable air is lifted vertically into the atmosphere. Lifting of this air results in condensation and the release of latent heat. The process to initiate vertical lifting can be caused by: (1).

What causes rainbow colors in clouds? When you see a cloud like this, you know there are especially tiny ice crystals or water droplets in the air. Larger ice crystals produce solar or lunar halos, but tiny ice crystals or water droplets cause light to be diffracted – spread out – creating this rainbow-like effect in the clouds. The phenomenon is called cloud iridescence or irisation. The term comes from Iris, the Greek personification of the rainbow.

Severe Weather 101 Why are there thunderstorms? Thunderstorms are a great way for the atmosphere to release energy. When warm moist air meets colder drier air, the warm air rises, the water vapor condenses in the air, and forms a cloud. As the water vapor condenses it releases heat, which is a form of energy.

Can a Propane Tank Explode? A propane tank explosion is a type of BLEVE, or Boiling Liquid Expanding Vapor Explosion. This type of explosion occurs when the pressure in the tank exceeds that which it can safely vent. Eventually, rising pressure will cause the tank to rupture and burst. Cause. A propane BLEVE occurs mainly when it is exposed to high temperatures, like a fire. The temperature heats the liquid propane inside the tank, causing it to expand to a point that the stress it places on the tank becomes too high. When propane gas leaks from the tank in a fire, it will ignite and can cause an explosion. Relief Valve. All propane tanks are equipped with a relief valve. When the pressure inside a tank rises, the relief valve opens and starts venting gas to bring the pressure down.

- Clouds can occur at any level of the atmosphere wherever there is sufficient moisture to allow condensation to take place. The layer of the atmosphere where almost all cloud exists is the troposphere, although the tops of some severe thunderstorms occasionally pierce the tropopause.

Cloud Formation: A Brief Explanation of How Do Clouds Form 1 As it rises higher and higher into the atmosphere, it begins to expand, thus releasing the moisture content. 2  This released moisture content/water vapor begins to condense as the temperature goes on dropping at higher altitudes. 3  This condensed moisture from the air results in the formation of clouds.

- How Do Severe Storms Begin? Thunderstorms require 3 main ingredients; a source of moist air, an unstable atmosphere and a trigger mechanism. Moist air is important because when it condenses to form cloud, heat energy is released making the rising air more heavier in some cases and faster moving.ll storms begin with Lightning and/or thunder. Lightning is the discharge produced when voltage differences between ground and atmospheric electrical charge are large enough to overcome the insulating effect of the air. Strokes can occur within the cloud, between clouds, or between clouds and the ground.
