Rain represent one form of presipitasi extant [of] dilution.
Presipitasi alone can be solid extant ( for example ices rain and snow) or
aerosol ( like fog and dew). Rain formed by if separate water dot fall to earth
of cloud. Do not all rainwater to surface of earth because some of condensing
when falling to [pass/through] dry air. Rain this type of conceived of by
virga. Rain is event go down him irrigate from sky to earth. Initially
rainwater come from water of uliginous earth of sea, river water, lake water,
accumulating basin water, irrigate rumpon, rice field water, irrigate comberan,
milk water, latrine water, pool water, spit, and others. Besides water which in
form of physical, water which condensing into the air also can come from human
being body, animal, flora, and also aqueous other objects.
The waters generally experience of evaporation process or
evaporation effect of existence of hot aid of sun. Water which condensing /
becoming vapour float into the air and finally continue to make a move to go to
high sky with other aqueous vapours. high in the sky the vapour experience of
condensation process or condensation so that form cloud. Constructively the
clouds wind can make a move vertical good, diagonal and horizontal.
Effect of peripatetic air or wind also clouds meeting each other
and big go to sky / earth atmosphere which is its temperature lower or chilled
and finally form ices item and water. Because weight and unable to be sustained
by wind finally items irrigate or the ice fall to surface of earth ( process presipitasi).
Because progressively lower excelsior air temperature hence formed snow or ice
melt to become water, but if its very low temperature hence will go down remain
to as snow.
Rain do not only going down in form of just ice and water, but
also can in form of fog and dew. Rain which fall to surface of earth if coming
in contact with dry air, some of rain can condense again into the air. Form
small rainwater is circular almost, while big more caper like burger, and
larger ones again in form of parachute. Big rain have speed of high water fall
so that sometimes felt pain if hitting our legs and hands.
Rain play role important in cycle of hydrology. Damp of sea
condense, turning into cloud, gathered to become overcast cloud, then go down
again to earth, and finally return to sea [pass/through] watercourse and river
to repeat that recycle initially.
Amount of rainwater measured to use or udometer of ombrometer. He is
expressed as gathered depth of water at surface level off, and measured more or
less 0.25mm.
Rain types pursuant to the happening of:
1. rain of Cyclonal, that is rain that happened because hot weather
which go up to be accompanied with rotary wind.
2. " rain of Zenithal, that is rain which often happened in area
of around ekuator, effect of meeting of North-East Trade Wind with Trade Wind
South-East. Later;Then the wind go up and form cloud I umps around equator
causing cloud become saturated and go down rain.
3. " rain of Orografis, that is rain that happened because
pregnant wind of horizontal peripatetic aqueous vapors. The wind go up to go to
mountain, air temperature become to be chilled so that happened condensation.
Happened [by] rain around mountain.
4. " rain of Frontal, that is rain that happened if cool air
mass come in contact with hot air mass. Meeting place among/between both that
mass is referred as by front area. Because is heavier of cool by air mass more
under. Around front area this is often happened torrential rains of[is
so-called rain of frontal.
Mousson rain or seasonal rain, that is rain that happened because
Monsoom( WindMousson). Cause the happening of Wind Mousson is caused by
movement of annual illusion of Sun
[among/between] Tropic Of Cancer and Tropic Of Capricorn. In Indonesia, mousson
rain happened October month;moon until April. Whereas [in] Asian area of East
happened May month; moon until August. this Cycle Mousson cause the existence
of rain season and dry season. excessive rain at one particular location can
generate disaster [at] life below/under him. Floods and landslide [is] one of the
effect of abundant rain. Change of climate under the sun recently also support
rain disseminating which [do] not flatten causing various problem under the
sun. For that we have its its his assist normally of climate changing effect of
act of human being so that/ to be our offspring later do not suffer and killed by
effect of mistake which we do/conduct in this time.
Allah say in the
qur’an:
Do
not you see that God drives the clouds, then joins them together, then piles
them on each other, then you see the rain comes forth from between them. And He
sends down hail from the sky, where there are mountains of it. And strikes
those with it whom He will and diverts it from whomever He wills. The vivid
flash of its lightning nearly blinds the sight.
