Clouds form when the water vapor condenses into small particles. The particles in clouds can either be liquid or solids. Liquid particles suspended in the atmosphere are referred to as cloud droplets and the solid particles are often called ice crystals. The potential for cloud formation (and precipitation) depends on the amount of water vapor in the atmosphere. As a parcel of air rises, the moisture it contains cools and condenses out onto small particles of dust called cloud condensation nuclei until a cloud forms.
As a volume of unsaturated air cools, its relative humidity increases. If sufficiently cooled, the relative humidity becomes 100%, the temperature equals the dew point. Here's a fun hands-on activity (applet) to help you explore the relationship between temperature, dew point temperature and relative humidity.
Lifting of AirLifting, 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 two main large scale lifting processes that result in cloud formation are convection and advection of air. Convection refers to air rising vertically in the atmosphere due to heating. Advection is the horizontal transfer of air that usually results in warmer air being forced up over cooler air. Both advection and convection results in the formation of clouds.
The method of vertical lifting (orographic, convective, convergence, or frontal) and the stability of the atmosphere determines the type of cloud. Cumulus clouds tend to form in unstable atmospheres. Layered cloudsform in more stable environments in which large layers of air are slowly lifted.
Cloud's RoleClouds play a crucial role in our global climate. Clouds reflect shortwave solar energy back into space and tend to cool the earth. On the other hand, clouds absorb longwave terrestrial radiation and warm the planet. Satellites are helping scientists study this important dynamic.
Clouds are not a gas. They are made up of very small water droplets. That is why the air is so damp when you are in fog. Clouds are moved along by wind, which is caused by a process of air cooling and heating. See the Web Link 'Meteorology' to the left for an explanation.
Your choice between two cooling devices will initially be influenced by 'how much heat you wish to transfer?', and 'at what temperature is that heat?'. Only then will you be able to proceed further.
So when they turn into clouds the water vapour condences into tiny droplets of water and it gets bigger and bigger it falls as rain
clouds are basically water that has evaporated.
nominal cooling capacity is the derated cooling capacity at a certain design condition. Rated cooling capacity is the cooling capacity at sea level

For an open machine thermal conduction and air-cooling are the only methods possible, sometimes with a fan to boost the flow of air.Oil-cooling and water-cooling can only be used on closed machines.
