Clouds are formed of micro-droplets of water. If the droplets merge together, they become drops and fall as rain, or freeze together and fall as sleet or snow. Sometimes they evaporate and become invisible water vapor. That’s how clouds disappear, the micro-droplets of water become another form or water.
The three primary ways that clouds dissipate is by (1) the temperature increasing, (2) the cloud mixing with drier air, or (3) the air sinking within the cloud. When the temperature increases, the air has a higher capacity to evaporate liquid water.
This of course begs the inquiry “What happens to clouds in the atmosphere when it gets hot?”
Usually clouds, after a period of time, just evaporate. Clouds are just large collections of condensed water droplets (or sometime ice crystals) helps aloft by the wind. When the temperature gets hot enough these water droplets/ ice crystals evaporate back into the air.
You should be asking “Why do clouds not remain adiabatic?”
One source stated that A cloud does not remain perfectly adiabatic (see tutorial below on adiabatic process). Some environmental air does mix into the cloud mass. If a cloud is no longer developing and not adding additional condensational moisture, the drier environmental air will gradually erode the cloud.
This of course begs the question “How does temperature affect the moisture content of a cloud?”
When the temperature increases, the air has a higher capacity to evaporate liquid water. When a cloud’s temperature increases, evaporation occurs and reduces the liquid moisture content of the cloud.
What are clouds made of?
Clouds are just large collections of condensed water droplets (or sometime ice crystals) helps aloft by the wind. When the temperature gets hot enough these water droplets/ ice crystals evaporate back into the air.
Why do clouds move in a high pressure system?
High pressure systems have colder air sinking downwards towards the centre from above, and due to coriolis effects, this will rotate around the centre as is pushes the lower air outwards. Similarly for lo Clouds move because of wind patterns in the atmosphere.
Generally, the winds and clouds move in a west-to-east direction overall, as if the Earth was spinning beneath them, but this is only a perceived effect. High pressure and low pressure systems have winds and clouds rotating clockwise and anti-clockwise in the northern hemisphere and the opposite in the southern hemisphere… wait, waht?
