Condensation is initiated by the formation of atomic/molecular clusters of that species within its gaseous volume—like rain drop or snow flake formation within clouds —or at the contact between such gaseous phase and a liquid or solid surface.

Much of the rain is produced by clouds whose tops do not extend to temperatures colder than 0° C. The mechanism responsible for rain formation in these "warm" clouds is merging or "coalescence" among cloud droplets, which are first formed by vapor condensation. Coalescence is probably the dominant rain-forming mechanism in the tropics.

2022年10月13日 · According to National Geographic, condensation is the opposite of evaporation and is the process where water vapor in the air becomes a liquid. It can happen in one of two ways. For...

2019年6月8日 · Condensation is the process by which water vapor in the air is changed into liquid water; it’s the opposite of evaporation. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface.

3 天之前 · The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

2023年3月24日 · Precipitation results when tiny condensation particles, through collision and coalescence, grow too large for the rising air to support, and thus fall to the Earth. Precipitation can be in the form of rain, hail, snow, or sleet. Precipitation …

Condensation is the process through which the physical state of matter changes from the gaseous phase into the liquid phase. For example, condensation occurs when water vapour (gaseous form) in the air changes into liquid water when it comes in contact with a cooler surface.

Water vapor pressure increases with temperature. Definitions of evaporation, evapotranspiration, condensation, and precipitation and how these processes relate to saturation water vapor pressure curve. The presence of condensation nuclei are critical for the formation of clouds. Mechanisms that result in warm and cold cloud formation.

2023年10月19日 · When clouds are saturated with water vapor, the density, or closeness, of the molecules increases. The vapor condenses and becomes rain. Cold air holds less water vapor than warm air. This is why warm climates are often more humid than cold ones: Water vapor remains in the air instead of condensing into rain.

2007年2月1日 · Our measurements of the isotopic composition of water vapour near tropical clouds suggest that rainfall evaporation contributes significantly to lower troposphere humidity, with typically 20% and...
