- As well, clouds are identified by the way in which they form. There are two basic types: cumulus and stratus. Cumulus clouds form in rising air currents and are evidence of unstable air conditions. Stratus clouds form in horizontal layers and usually form as a layer of moist air is cooled below its saturation point.

How Clouds Are Made? Quick Answer. Clouds form when warm, moist air rises into the upper atmosphere, where the cooler temperatures cause the water to condense. Depending on the altitude, clouds may be made up of water droplets or ice crystals, and these often form around floating motes of dust or other particles.

How are clouds formed? This is cloud. They are usually white by irregular reflection . Rain cloud is dark because their water drops are rather large and less transparent. There are many chances when cloud is formed. For example towering thundercloud is formed when air rises high up in the sky.

Clouds Cumulus clouds are fair-weather clouds. When they get big enough to produce thunderstorms, they are called cumulonimbus. These clouds are formed by upwelling plumes of hot air, which produce visible turbulence on their upper surfaces, making them look as though they are boiling.

Stratiform Understanding How Clouds are Formed. Clouds are not magical structures that appear in the skies. They exist for a reason and they are responsible for the weather. More than just beautiful cottony structures, clouds are made up of ice or water. They are formed because air rises and then cools as they expand.

- Ingrediants for making a cloud: water aerosols wind In a basic vocabulary, clouds are made in this order: 1st: water evaporates from oceans, lakes, ponds, puddles, ect 2nd: wa … ter enters the atmosphere and forms into water vapor 3rd: as the water vapor goes up, it reaches its dew point and turns back into water droplets 4th: those water droplets cling on to aerosols (salt, dust, particles in the air) that the wind carries in the air 5th: Cloud is formed.

Orographic lift A gravity wave cloud pattern—analogous to a ship wake—in the downwind zone behind the Île Amsterdam, in the far southern Indian Ocean. The island generates wave motion in the wind passing over it, creating regularly spaced orographic clouds. The wave crests raise and cool the air to form clouds, while the troughs remain too low for cloud formation. Note that while the wave motion is generated by orographic lift, it is not required. In other words, one cloud often forms at the peak. See wave cloud. Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain.

Funnel clouds But in hotspots such as tornado alley in the USA, funnel clouds can sometimes be thicker and much more intense. How do funnel clouds form? A rotating column of wind draws in cloud droplets, making a region of intense low pressure visible. They are formed in the same way as a tornado building around this localised area of intensely low pressure and are typically associated with the formation of cumulonimbus thunderclouds.

CLOUD ATLAS Fair weather cumulus clouds form when a parcel of air rises and water vapor condenses into water droplets. This is a classic case of stratus clouds. The sky has a sheet-like grey covering and the sun is not visible. Stratocumulus clouds form a clumpy layering across the sky. They are not as well-defined or as well-separated as fair weather cumulus clouds are.

- The ascent of the warm air causes it to cool, and clouds are formed, ranging from high cirrus through altostratus down to thick nimbostratus from which continuous steady rain may fall over a wide area. frontal lift. When a mass of cold air is advancing on a mass of warm air.

What are clouds? Clouds form when the invisible water vapour in the air condenses into visible water droplets or ice crystals. There is water around us all the time in the form of tiny gas particles, also known as water vapour. There are also tiny particles floating around in the air - such as salt and dust - these are called aerosols.

- Origin: 1  By rise of an expanded air layer at the border of a rising zone. 2  By convection or turbulence within an unstable layer of the middle cloud level. 3  By transformation from Altostratus und Nimbostratus at lability or Cumulus and Cumulonimbus at stability.

- Anvil clouds, which are mostly composed of ice particles, form in the upper parts of thunderstorms. They get their anvil shape from the fact that the rising air in thunderstorms expands and spreads out as the air bumps up against the bottom of the stratosphere.

Cumulonimbus cloud Cumulonimbus, from the Latin cumulus and nimbus, is a dense, towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along cold front squall lines. These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes. Cumulonimbus progress from overdev

- The left image pair shows a cold front moving from left to right into a warm mass of air. The cold, dense air lifts the warm air like a wedge. The rising, warm air forms distinctive anvil-shaped clouds, visible in both the satellite and model image.

Thunder and lightning Typically, these cumulonimbus clouds can form in under an hour. As the warm air continues to rise, the water droplets combine to create larger droplets which freeze to form ice crystals. As result of circulating air in the clouds, water freezes on the surface of the droplet or crystal.

Undulatus Asperatus Advertisement. Those are undulatus asperatus (agitated or turbulent wave) clouds, a type of cloud that is starting to get consideration as a wholly new category. From what I can tell, they are formed when there’s rising air that creates wide-spread cloud cover, together with wind shear that blows across the rising air.

Types of Clouds Clouds form in three basic patterns: 1  Cirrus, from cirro, meaning curly or fibrous. 2  Stratus, from strato, suggesting sheets or layers. 3  Cumulus, from cumulo, indicating heaped or piled.

Thunder and lightning Thunderstorms develop when the atmosphere is unstable-this is when warm air exists underneath much colder air. As the warm air rises it cools and condenses forming small droplets of water. If there is enough instability in the air, the updraft of warm air is rapid and the water vapour will quickly form a cumulonimbus cloud. Typically, these cumulonimbus clouds can form in under an hour. As the warm air continues to rise, the water droplets combine to create larger droplets which freeze to form ice crystals. As result of circulating air in the clouds, water freezes on the surface of the droplet or crystal.

How do nimbostratus clouds form? Nimbostratus are thick homogeneous rain clouds formed by air saturating by increasingly thickening cloud at a warm front. Their depth runs from near ground level to high levels- over 20,000 feet. Rain, often heavy, falls as soon as the dew point is reached in the saturated air. The rain may last for several hours depending on how fast the frontal system is moving. Once the Warm front has passed it is usually followed by a cold front bringing showery weather from cumulus clouds.

- As the surface of the earth heats up due to incoming solar radiation, warm bubbles of air (thermals) develop and begin to rise. When these thermals reach a height known as the condensation level, cumulus clouds begin to form. Cooler air surrounding the clouds sinks to replace the warm air rising from the surface.

Cloud Clouds initially form in clear air or become clouds when fog rises above surface level. The genus of a newly formed cloud is determined mainly by air mass characteristics such as stability and moisture content. If these characteristics change over time, the genus tends to change accordingly.

Thunderstorm Thunderstorms develop by the same process that forms cumulus clouds, the puffy clouds of summer skies. These clouds form when a humid air mass (air with an abundance of water vapor) near the surface rises on currents of air called updrafts. As the air mass rises through the atmosphere it expands and cools.
