THE PROCESS OF RAIN

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.
