why cloud rain in rainy season not in summer?

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.

In order for it to rain, there needs to be a low pressure system over you as well..besides evaporation.  During the summer, low and high pressure belts move.  That's why some places that are dry all year have a really rainy season and normally rainy places get no rain during the summer.

A cloud is a visible mass of condensed droplets or frozen crystals suspended in the atmosphere above the surface of the Earth or another planetary body. The branch of meteorology in which clouds are studied is nephology.\n\nOn Earth, the condensing substance is water vapor, which forms small droplets of water or ice crystals, typically 0.01 mm in diameter. When surrounded with billions of other droplets or crystals, they are visible as clouds. Dense deep clouds exhibit a high reflectance (70% to 95%) throughout the visible range of wavelengths: they thus appear white, at least from the top. Cloud droplets tend to scatter light very efficiently, so that the intensity of the solar radiation decreases with depth into the cloud, hence the grey or even sometimes dark appearance of the clouds at their base. Thin clouds may appear to have acquired the color of their environment or background, and clouds illuminated by non-white light, such as during sunrise or sunset, may be colored accordingly. In the near-infrared range, however, clouds would appear very dark because the water that constitutes the cloud droplets strongly absorbs solar radiation at these wavelengths.\n\nCloud formation and properties\nClouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. This can happen in three ways:\n\n1. The air is cooled below its saturation point. This happens when the air comes in contact with a cold surface or a surface that is cooling by radiation, or the air is cooled by adiabatic expansion (rising). This can happen:\n* along warm and cold fronts (frontal lift)\n* where air flows up the side of a mountain and cools as it rises higher into the atmosphere (orographic lift)\n* by the convection caused by the warming of a surface by insolation (diurnal heating)\n* when warm air blows over a colder surface such as a cool body of water.\n\n2. Clouds can be formed when two air masses below saturation point mix. Examples are breath on a cold day, aircraft contrails and Arctic sea smoke.\n\n3. The air stays the same temperature but absorbs more water vapor into it until it reaches saturation point.\n\nThe water in a typical cloud can have a mass of up to several million tonnes. However, the volume of a cloud is correspondingly high, and the net density of the relatively warm air holding the droplets is low enough that air currents below and within the cloud are capable of keeping it suspended. As well, conditions inside a cloud are not static: water droplets are constantly forming and re-evaporating. A typical cloud droplet has a radius on the order of 1 x 10-5 m and a terminal velocity of about 1-2 cm/s. This gives these droplets plenty of time to re-evaporate as they fall into the warmer air beneath the cloud.\nCumulonimbus cloud\nEnlarge\nCumulonimbus cloud\n\nMost water droplets are formed when water vapor condenses around a condensation nucleus, a tiny particle of smoke, dust, ash, or salt. In supersaturated conditions, water droplets may act as condensation nuclei.\n\nWater droplets large enough to fall to the ground are produced in two ways. The most important means is through the Bergeron Process, theorized by Tor Bergeron, in which supercooled water droplets and ice crystals in a cloud interact to produce the rapid growth of ice crystals; these crystals precipitate from the cloud and melt as they fall. This process typically takes place in clouds with tops cooler than -15°C. The second most important process is the collision and wake capture process, occurring in clouds with warmer tops, in which the collision of rising and falling water droplets produces larger and larger droplets, which are eventually heavy enough to overcome air currents in the cloud and the updraft beneath it and fall as rain. As a droplet falls through the smaller droplets which surround it, it produces a "wake" which draws some of the smaller droplets into collisions, perpetuating the process. This meth

clouds fall all the time, in the form of rain or snow. The cloud is not a container for moisture, it IS the moisture.  \n\nLuckily, it falls gently or heavily, but not all at once!  I think maybe you were asking "what if a cloud fell all at once," in which case I'd say YIKES.  Kind of like a tsunami from the sky, I guess!

Clouds are mists of water droplets that have condensed out of water vapour at "dewpoint", which is dependent on temperature, pressure, and humidity.\n\nThere is no intelligence or knowing involved.\n\nClouds don't fly, they are blown by the wind.

The weight of water equals the weight of the cloud, since the cloud is nothing but water. If it loses water by raining, the cloud loses that amount of weight.

We have air around us. The atmosphere has high preasure and low preasure. When the high preasure area turns into low preasure, the air moves from high preasure area towards the low preasure. This movement of air from one area to another causes the wind. \n\nIt has nothing to do with clouds. The faster the low preasure area is formed, depends on whether you have clouds, or thunderstorms. Low preasure areas causes rain. This is why normally you have winds before the rain.

I live in sunny southern california and the reasons why I love this place is because of the nice weather. Rain is not really in the nice weather catagory sorry. I need the sun for energy. I get lazy when it rains. I over slept when it rains. However having said that, I think sometimes the rain is very romantic if you're in certain areas like a hut with palm trees and stuff. You end up writing poems and love songs while the rain trikles above the roof of the house. ANd usually when it stops raining, a beautiful rainbow appears. But again, I prefer the sun with clear beautiful blue skys.

Clouds are made of water vapor.  You inhale clouds every time you walk into a patch of fog, because fog is just a cloud at ground level.  Clouds are formed when water evaporates from the surface of the Earth and makes its way upward.  The water condenses and we get a cloud.  When clouds get too laden with water, it falls in liquid form and we get rain.

Yes it does decrease because cold air can hold less water vapour than warm air. So at altitude water vapour gets "squeezed out" and forms droplets which make clouds and fall as rain.

Why do people ask such questions?\n\nIf there is an obstacle to the flow of the air, of course it's gonna change the climate and temperatures because the air flow cannot go through mountains barriers, it will clash against it and part of it will go over it.\n\nBut the point is, if it was a cool air flow in hot summer ( happens sometimes but you'll have to ask another question on this subject), the sky will get all the cool air but because of the mountains barriers the lower part of the flow will not go through, that is how we get rain on hot days!

In general, very high mountains block rain bearing clouds.  This is true in the Great Plains, where the Rocky Mountains block rain clouds, and produce a dry environment on the east side of the mountains.\n\nFind out what the rainfall patterns are in the area of interest, and see if this applies to your problem.

There are a couple of reasons that work together to explain this situation. The first one has to do with how raindrops form. \n\nNow, it may seem silly to make such an obvious statement as, "Rain always falls from clouds." But once it has been said, we can then ask, "What is going on inside those clouds?" And that question leads us to plenty of relevant information! \n\nDo you remember the last time your local weather was described as being "hot and humid"? Do you remember what it FELT like? Do you also remember what the air LOOKED like? The reason I am asking these questions is because it is important to know that ordinary water is commonly found in one of three forms: solid, liquid, or gas. The liquid form is what we call "water", while the solid form we call "ice", and the gas form we call "water vapor". Water vapor is colorless, odorless, and invisible. But you sure can FEEL it on a hot and humid day! \n\nNext, do you remember the last time you encountered some fog? Think about what IT looked like. If you looked real close, you would have seen zillions of tiny tiny droplets of water floating in the air. And, if you remember the last time you saw some steam, you might think that it looked just like fog (except it was hotter). Steam is NOT pure water vapor! \n\nWell, it happens that the description, "zillions of tiny tiny droplets of water floating in the air", applies to every fog, to every mist, to every burst of steam -- and to every cloud in the sky. If you sit back and simply watch the clouds for a while, you will see that some clouds grow, some shrink, and some do nothing but move across the sky. What is happening to the growing or shrinking clouds? When a cloud grows, water vapor in the air gradually "condenses" to form lots more tiny tiny droplets. When a cloud shrinks, many droplets are completely "evaporating" to become invisible water vapor. \n\nAs the winds move air across the sky, carrying clouds along, fragments of wind known as "eddys" can do strange things to the shapes of clouds. A common game is to study a cloud's shape and guess what it looks like. Also, winds from different directions can collide with each other, which often has great effects upon clouds. It depends on how cold or warm the colliding winds are, and how much water each wind carries (only the differences matter, not whether the water is in the form of vapor or tiny drops). \n\nFor rain to happen, the weather conditions inside the clouds, and surrounding them, has to cause the droplets to grow. Some droplets will grow by colliding and combining with each other -- just what you Asked about. Some droplets will grow by acquiring more and more water vapor from the air. Some will do both. But the important thing to remember now is that MOST of the droplets in the clouds grow at the same time! \n\nBUT, the droplets do not all grow at the same rate; some grow faster than others. As soon as ANY get big enough, they start to fall out of the cloud. Water is heavier than air, after all. Depending on the wind conditions, those first raindrops might be blown back up into the cloud, where they can grow some more. Eventually, however, they get too big to stay up in the air, so they fall all the way to the ground. And the slower-growing droplets will fall after them, and the slower-growing-yet droplets will fall after THEM, and so on. This is the essence of the raining process. \n\nAs I said at the start, there are a couple of reasons why the raindrops don't combine to make a single stream. The first reason is simply that raindrops start falling just as soon as they are too heavy to stay in the air. The second reason is that they are all falling together DOWNWARDS, not sideways. If the wind blows them sideways, they all move TOGETHER sideways. That isn't good enough to cause them to meet each other, while falling, so they could combine to form a si

The water's in a vapor form which makes it much much lighter than if it were in liquid form, and there are air currents within clouds that keep the vapor circulating around and are able to hold the water up against gravity.  It's when water vapor starts forming droplets that it gets too heavy for clouds and we get rain, hail, etc.

When moist air cools (air collects moisture through evaporation) that moisture starts to condense (think the side of your can of pop in the summer with all the droplets on it).  That's what clouds are, condensation.  Back to the pop can, when too much moisture collects on the side, it starts to run down the can.  That's what happens in the cloud -- too much moisture causes precipitation (rain).

The clouds hang in the air due to buoyancy (density of water vapour is less than air). At higher altitudes the air becomes thinner and force of buoyancy is lesser. so they cant hang at higher altitudes.

in localized area's rain may come in any direction.  But in reginal scale, rain generally comes from the west due to coriolis effect & the cold air coming down from higher lattitude.\n\nAlso, when cold & warm air are mixing, cold air catches up the warm air from behind in counter-clockwise rotation, which produces rain / storm.
