How do water droplets in clouds cohere?

Clouds are formed when gaseous water molecules inside them concentrate on small solid particles suspended in the air as the air cools. As the air rises in the atmosphere, its pressure decreases. As a result, as it expands, that is, its volume increases, its temperature decreases. At lower temperatures, the amount of water vapor that the air can hold decreases. When the saturation point is reached, small drops of water begin to form in the air. The point where air carries enough water vapor to carry water molecules before they become liquid is called the saturation point. Clouds become visible when the size of the droplets exceeds a few micrometers.

It is thought that the coexistence of clouds in the form of heaps rather than homogeneously dispersed in the sky is due to the imbalance of temperature and humidity in the atmosphere. The energy from the sun during the day to change the temperature of the atmosphere and causes the emergence of different short distances. The saturation point, which is a determining factor in the formation of clouds, is closely related to the temperature of the atmosphere. In addition, since the moisture is not evenly distributed in the air, a border emerges between the region where the clouds are formed and its surroundings. The relative humidity difference between the region where the clouds are formed and its surroundings is high, while the high relative humidity around the clouds makes the clouds spread along the border line.
