what are the 3 requirements for cloud formation?

There must be three main ingredients present in order for clouds to form: Moisture - There must be sufficient water vapor in the air to build a cloud. Cooling air - The air temperature must decrease enough for water vapor to condense.

['It must orbit a star (in our cosmic neighborhood, the Sun).', 'It must be big enough to have enough gravity to force it into a spherical shape.', 'It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.']

There are three main types of clouds. The stratus, the cumulus, and the cirrus.

The types of clouds can be divided into three levels, each in turn with its own main groups of clouds. All in all, there are ten fundamental types of clouds. Often, you'll some places simply class clouds as cirrus, stratus, and cumulus because these clouds are the most common and representative for each altitude class.

In order for a thunderstorm to form, there are three basic ingredients that are essential, and are what we look for to provide a severe weather forecast. These three ingredients include moisture, rising unstable air, and a lifting mechanism. Moisture: A moisture supply is essential, of course.

['Low-level clouds (cumulus, stratus, stratocumulus) that lie below 6,500 feet (1,981 m)', 'Middle clouds (altocumulus, nimbostratus, altostratus) that form between 6,500 and 20,000 feet (1981–6,096 m)', 'High-level clouds (cirrus, cirrocumulus, cirrostratus) that form above 20,000 feet (6,096 m)']

There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to sustain a low pressure center, a preexisting low level focus or disturbance, and low vertical wind ...

Cloud names and classifications. The classification of clouds into types was first proposed by Luke Howard in 1802 and we largely use the same system today. This splits clouds into three main types - stratus, cumulus and cirrus. Clouds are continually changing and appear in an infinite variety of forms.

The different types of clouds are cumulus, cirrus, stratus and nimbus.

Methodology. The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide.

Solution: 1) The air must contain water vapor that can precipitate, 2) the moist air must cool down in order to release water in liquid form, and 3) there must be condensation nuclei for water vapor to condensate on.

Clouds are generally encountered over a range of heights between the ground and about 60,000 feet. By convention, the atmosphere is vertically divided into three levels: high, middle and low.

Three types of clouds Clouds form in three basic patterns: Cirrus, from cirro, meaning curly or fibrous. Stratus, from strato, suggesting sheets or layers. Cumulus, from cumulo, indicating heaped or piled.

Bases of these clouds are generally no more than 3,000 feet above the ground, but they can develop past the troposphere in both temperate and tropical latitudes. Cumulus clouds are classified as low yet vertically building clouds.

Cumulonimbus clouds are thunderstorm clouds that form if cumulus congestus clouds continue to grow vertically. Their dark bases may be no more than 300 m (1000 ft) above the Earth's surface. Their tops may extend upward to over 12,000 m (39,000 ft).
