Cloud Formation

Condensation or Deposition of Water

Clouds is form form when the water vapor condense into small particle .
The particles is be in cloud can either be liquid or solid . liquid particle suspend
in the atmosphere are refer to as cloud droplet and the solid particle are often
call ice crystal . The potential is depends for cloud formation ( and precipitation ) depend
on the amount of water vapor in the atmosphere . As a parcel of air rise , the moisture
it contain cool and condense out onto small particle of dust call cloud condensation
nucleus until a cloud form .

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 Air

lifting , also refer to as adiabatic cooling ,
is the most common method of humidification of air to form cloud . As air rise it is expands
expand because pressure decrease with altitude . kinetic energy is convert to potential
energy and the parcel temperature decrease , and the relative humidity increase .

The two main large scale is are lift process that result in cloud formation are convection
and advection of air . Convection is refers refer to air rise vertically in
the atmosphere due to heating . Advection is is is the horizontal transfer
of air that usually result in warm air being force up over cool air . Both advection
and convection result in the formation of cloud .

The method is determines of vertical lifting ( orographic , convective , convergence , or frontal ) and
the stability of the atmosphere determine the type of cloud . cumulus clouds is tend tend
to form in unstable atmosphere . layered clouds is form form in more stable
environment in which large layer of air are slowly lift .

Cloud ‘s role

Clouds 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.
