The most important process of cloud formation in the atmosphere is: -cooling by compression of air.
The process of water changing from a gas to a liquid is called "condensation," and when gas changes directly into a solid, it is called "deposition." These two processes are how clouds form.
The air high above the air is colder than air at the surface. The vapor rises until it reaches a low enough temperature and pressure to condense water vapor into water droplets and form a cloud.

Rising warm air cools, resulting in cloud formation and rain. Why does rain occur near a warm front? Rising warm air cools, resulting in cloud formation and rain. What causes the development of most clouds and precipitation in the atmosphere?
Water present on the earth's surface gets evaporated due to sunlight, and then rises up in the atmosphere. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.
Lifting of Air Lifting, also referred to as adiabatic cooling, is the most common method of humidification of air to form clouds. As air rises it expands because pressure decreases with altitude. Kinetic energy is converted to potential energy and the parcel temperature decreases, and the relative humidity increases.
The stratosphere is very dry air and contains little water vapor. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere.
When warm air rises, it expands and cools. Cool air can't hold as much water vapor as warm air, so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together, they become a visible cloud.
