why does rainfall decrease from east to west in india?

Winds pick up water vapor as they blow across oceans, and drop the water as rain as they blow across islands and  continents, generally losing more water as the elevation rises.  \n\nAs the air and clouds blow over higher ground, the temperature drops and causes the water to precipitate, forming rain.  There is a "rain shadow," on the leeward side of the higher ground in the center of an island or continent, because the clouds drop the rain on the "windward" side of a mountain (side toward the wind), leaving the "leeward" side drier (side that's sheltered from the wind).\n\nThe winds blowing across the ocean pick up water and bring rain to India, bringing more rain as they first come to the land, raining as the elevation rises, and then raining less after they cross the higher ground in the central parts of India. \n\nHope this helps.

Well part of it is absorbed by the oceans which are giant heat sinks and of course a lion share is used up condensing water out those cold clouds to make rain.  If you follow this train of thought out the rain gets absorbed by trees which grow up to become fire wood for people to burn in their campfires.  And round and round we go.

INDIAN geography---\n\nThe territory of India constitutes a major portion of the Indian subcontinent, situated on the Indian Plate, the northerly portion of the Indo-Australian Plate, in southern Asia. India's northern and northeastern states are partially situated in the Himalayan Mountain Range. The rest of northern, central and eastern India consists of the fertile Indo-Gangetic plain. In the west, bordering southeast Pakistan, lies the Thar Desert. The southern Indian Peninsula is almost entirely composed of the Deccan plateau, which is flanked by two hilly coastal ranges, the Western Ghats and Eastern Ghats.\n\nIndia is home to several major rivers, including the Ganga, Brahmaputra, Yamuna, Godavari, Kaveri, Narmada, and Krishna. India has three archipelagos – Lakshadweep off the southwest coast, the Andaman and Nicobar Islands-volcanic island chain to the southeast, and the Sunderbans in the Gangetic delta in West Bengal.\n\nClimate in India varies from tropical in the south to more temperate in the Himalayan north, with elevated regions in the north receiving sustained snowfall in winters. India's climate is strongly influenced by the Himalayas and the Thar Desert. The Himalayas, along with the Hindu Kush mountains in Pakistan, provide a barrier to the cold winds from Central Asia. This keeps most of the Indian subcontinent warmer than most locations in similar latitudes. The Thar Desert is responsible for attracting the moisture laden southwest monsoon winds that provide most of India's rainfall between June and September.\n\n\nfor more info\nsee this link--\n\nhttp://en.wikipedia.org/wiki/Geography_of_India

Easy -- say the total yearly rainfall is 24 inches.\n\nOkay, in one place it rains 24 inches in one month -- and is dry the rest of the year.\n\nIn the other, it rains 2 inches per month, each and every month.\n\nExtreme examples, but obviously these would be two VERY different climates!!

Monsoons are flood rains that occur mainly in the Asian countries such as India, Bangladesh and others. It's part of their cycle of rainy and non-rainy seasons. The physical process would be a part of the water cycle but also coupled with atmospheric disturbances specific to the regions affected by these conditions.

Earlier it was Cherapunji, India but now I think the record of highest rainfall has surpased in a different place. I am sorry, I  can't get the name right now!

It depends on where you live. Many parts of the world get lots of rain and clouds in the summertime. \n\nYou may live in a mediterranean climate, where the local weather pattern is rainy winters and dry summers. The reasons for this vary from locale to locale. In the town that I'm writing from, there's a mountain that blocks the cool, moist winds that blow most of the year. We can get a lot of rain coming from the other direction, but the winds only blow that way in wintertime. \n\nTo know exactly why you have those weather conditions, I would need to know where you live.

Monsoons are caused by the fact that land heats up and cools down more quickly than water. Thus, in summer, land reaches a higher temperature than the ocean. The hot air over the land tends to rise, creating an area of low pressure. This creates an extremely constant wind blowing toward the land. Associated rainfall is caused by the moist ocean air being diverted upward by mountains, which causes cooling, and in turn, condensation.\n\nIn winter, the land cools off quickly, but the ocean retains heat longer. The hot air over the ocean rises, creating a low pressure area and a breeze from land to ocean. Because the temperature difference between the ocean and land is less than in summer, the winter monsoon wind is not as constant.\n\nMonsoons are similar to sea breezes, but they are much larger in scale, stronger, and are more constant and fast.

The climate of Manipur, which Jawaharlal Nehru called the 'Jewel of India', is moderate throughout the year. \nThe valley gets the reflection of the heat of the summer and the cold of the winter from the neighbouring hills. \nThe months of November, December, January and February remain dry and the remaining eight months are more or less rainy. January is very cold in winter and May-June are the hottest in summer.

Water loss from leaves is called transpiration and is greatest when it is hot.\nWhen a mass of warm, moist air is cooled the water vapour will condense and clouds are seen. As cooling progresses the droplets coalesce and fall as rain.\nThis cycle is most obvious in rain forests.\nBoth transpiration and evaporation from the sea and lakes contribute to water vapour in the air, but over continental areas transpiration from trees is of greater importance. Deforestation in these areas leads to dessertification.

Put simply, the earth spins from west to east so there is a drag of air (and water) from east to west as it partly resists the earth's motion.\n\nThis effect is most pronounced at the equator which is spinning fastest. Hence there are strong ocean and wind currents from east to west along the equator. The trade winds are sucked into the wake or tail of this from the north and the south. So in the northern hemisphere they are northeast to southwest, in the southern hemispere they are southeast to northwest.

Red rain in Kerala was a phenomenon observed sporadically from 25 July to 23 September 2001 in the southern Indian state of Kerala. Heavy downpours occurred in which the rain was primarily red, staining clothes and appearing like blood.[1] Yellow, green, and black rains were also reported. [1]\n\nIt was initially suspected that the rains were colored by fallout from a hypothetical meteor burst, but the Government of India commissioned a study which found the rains had been colored by spores from a locally prolific aerial algae.[2] Then in early 2006, the Keralan colored rains suddenly rose to worldwide attention after media reports of an extraordinary theory that the colored particles are extraterrestrial cells, proposed by Godfrey Louis and Santhosh Kumar of the Mahatma Gandhi University in Kottayam.\n\nThe colored rain of Kerala first fell on 25 July 2001, in the districts of Kottayam and Idukki in the southern part of the state. Some reports suggested that other colors of rain were also seen.[3] Many more occurrences of the red rain were reported over the following 10 days, and then with diminishing frequency until late September.\n\nAccording to locals, the first colored rain was preceded by a loud thunderclap and flash of light, and followed by groves of trees shedding shriveled gray "burnt" leaves. Shriveled leaves and the disappearance and sudden formation of wells were also reported around the same time in the area.[4][5][6]\n\nThe coloration of the rain was due to red particles in suspension in the rain water, and when it fell, the red rain was at times as strongly coloured as blood. It typically fell over small areas, no more than a few square kilometres in size, and was sometimes so localised that normal rain could be falling just a few metres away from red rain. Red rainfalls typically lasted less than 20 minutes.[7]\n\nIntial report\nShortly after the first fall of the red rain, it was reported in the media that scientists at the Center for Earth Science Studies and the Tropical Botanic Garden and Research Institute had determined that the particles coloring the rainwater were some type of spore [2]. Then in November of 2001, commissioned by the Government of India's Department of Science & Technology, the CESS and TBGRI released a report which concluded that Kerala's rains were colored by algae spores, which were successfully grown in medium into lichen-forming algae of the Trentepohlia genus. This algae was found to be associated with lichens in the trees in Changanacherry area [8].\n\nThe report also stated that there were no dust of meteoric, volcanic or desert origin present in the rainwater, and that the colour of the rainwater was not due to any dissolved gases or pollutants. The report suggested that heavy rains in Kerala in the weeks preceding the red rains could have caused the widespread growth of lichens, which had given rise to a large quantity of spores in the atmosphere. However, it found no unequivocal mechanism for the apparent extraordinary dispersal of the suspect spores, nor for the uptake of the suspect spores into clouds.\n\nThe authors of the report analysed some sediment collected from the red rains, using a combination of techniques of ion-coupled plasma mass spectrometry, atomic absorption spectrometry and wet chemical methods. The major elements found are listed below.\n\nMajor elements present in the dried sediment Element Weight % \nAl 1.00 \nK 0.26 \nMg 1.48 \nCa 2.52 \nNa 0.49 \nFe 0.61 \nSi 7.50 \nC 51.00 \nP 0.08 \n\nThe presence of aluminium and the very low content of phosphorus is puzzling because aluminium is not ordinarily found in living cells while such cells can normally be expected to contain about 3% phosphorus can be expected in the dry weight of biological cells.[3]\n\nConventional Theories\nHistory records many instances of unusual objects falling with the rain — in 2000, in an example of raining animals, a small waterspout in the North Sea sucked u

Read through this article, which talks about agriculture in India. You can search for the references to irrigation, particularly in the sections on the Indo-Gangetic Plain and Peninsular India, where it describes the importance of irrigation in these regions. Even though large parts of India are subject to monsoon rains in the summer, there is still a need for irrigation to ensure year-round crops. (Remember, in much of India, is is warm enough to grow things year-round.)\nHope this helps.

tradewinds\n"During El Niño events, the normal pattern relaxes. The tradewinds weaken, particularly west of the Dateline, and the piled-up water in the west sloshes back east, carrying the warm pool with it. The region of rising air moves east with the warm pool, and so does the pumping of heat and moisture into the upper atmosphere. Deflections in the normal wind patterns distort the usual paths of the jetstreams, pushing them from their accustomed places, which eventually causes the changes in the weather that the rest of the world experiences. With weakened tradewinds, the deep cool waters coming up in the east slow their ascent. The food supply for plankton dwindles, and the effect travels up the food chain. When eastern sea surface temperature becomes warm, the east-to-west temperature contrast is small, and so the tradewinds weaken even further, leading to a complete collapse with essentially flat conditions across the entire equatorial Pacific."

Must have rained harder there! Rainfall measurements are averages.
