A mushroom cloud is a distinctive mushroom-shaped cloud of smoke, flame, or debris resulting from a very large explosion. They are most commonly associated with nuclear explosions, but any sufficiently large blast will produce the same sort of effect. Volcano eruptions and impact events can produce natural mushroom clouds.\n\nMushroom clouds form as a result of the sudden formation of a large mass of hot low-density gases near the ground creating a Rayleigh-Taylor instability. The mass of gas rises rapidly, resulting in turbulent vortices curling downward around its edges and drawing up a column of additional smoke and debris in the center to form its "stem". The mass of gas eventually reaches an altitude where it is no longer less dense than the surrounding air and disperses, the debris drawn upward from the ground scattering and drifting back down (see fallout).\n\nThe largest mushroom clouds to be photographed resulted from the impact of fragments of Comet Shoemaker-Levy 9 on the planet Jupiter, some of which rose hundreds of kilometers above the cloud layers.\nMushroom clouds are formed by many sorts of large explosions, though they are best known for their appearance after nuclear detonations. Nuclear weapons are usually detonated above the ground (not upon impact,or else they would dig a big hole in the ground) in order to maximize the effect of their spherical expanding fireball. After immediate detonation, the fireball itself begins to rise into the air, acting on the same principle as a hot-air balloon.

rain comes from clouds. clouds are actually water vapour floating in air. when they become really condensed due to a drop in temperature then they form large drop of water which cant stay afloat and so rain happens.

Clouds are formed when water vapour in the air is cooled and condenses as part of the water cycle. Clouds consist of billions of tiny water droplets (and even ice crystals) floating in the sky and appear in a variety of shapes and sizes depending on how and where they formed.

The first thing to come to my mind is if you're talking about convective rainfall, which requires the ground to heat up.  If you have a layer of say altostratus clouds (with no precip) move over an area, the solar heating will decrease and this could halt any convective clouds that may have been forming, and which may have produced rain if the heating had continued.  But this is just off the top of my head.

Sleet is formed by snow (single ice crystals) being formed in cold clouds and then falling through warmer air so that they begin to partially melt, falling as wet snow - sleet.\n\nHailstones form by water droplets freezing very quickly in a cloud so that they form a small blob or nucleus rather than the larger crystal formed by a slow freezing snow flake crystal. The nucleus continues to fall through the cloud until it meets a strong upcurrent of warmer damper air coming up from the ground.  This blows the ice droplet up into the colder part of the cloud.  the warm air surrounding the nucleus cools and the water in it condenses out and freezes onto the surface of the existing ice droplet making it larger and heavier.  This is cycle isrepeated until the updraught is not strong enough to keep the hailstone airborne and it (and the millions of others with it) drop to the ground.\n\nThe stronger the updraught the larger the final hailstone.\n\nIf you collect some hailstones after they have dropped and use a sharp knife to cleanly cut one in half, you might be able to see the individuals layers of ice within the hailstone through a magnifying glass or microscope.\n\nHailstones can become very very big - have alook at the guiness book of records - but I believe that you Americans hold the record for a hailstone that fell in Kansas, USA, and was measured at 43.18cm (17 in) long - unfortunately no idea of the weight.

A nimbus cloud is a dark precipituous cloud. Nimbus is a Latin word meaning cloud or rain storm. The prefix nimbo- or the suffix -nimbus indicates a precipituous cloud; for example, a nimbostratus cloud is a precipituous stratus cloud, and a cumulonimbus cloud is a precipitous cumulus cloud.

There are multiple types of clouds because not all clouds are made the same way. The weather and climate is different everywhere at different times of day and seasons, so the way the clouds are being made can be different, too.\n\nClouds are divided into two general categories: layered and convective. These are named stratus clouds and cumulus clouds. These two cloud types are divided into four more groups that distinguish the cloud's altitude. Clouds are classified by the cloud base height not the cloud top.\n\nClick on the link below for more information! Hope this helps.

Cirrus clouds form at high altitudes and usually don't create precipitation. Also, any other form of high-level cloud, such as altocumulus, altostratus, etc. usually don't produce precipitation that reaches the ground.

G'day Siva K,\n\nThank you for your question.\n\nIt is commonly called cloud seeding. It is normally done by using aircraft to place silver iodide or dry ice into potential rain clouds to increase the amount of rain. There are two types of suitable clouds for the process - cumulus and stratus.\n\nIt is widely used in China and Australia.\n\nI have attached sources for your reference.\n\nRegards

There are three main cloud types.\n\nCumulus clouds are the puffy clouds that look like puffs of cotton. Cumulus clouds that do not get very tall are indicators of fair weather. If they do grow tall, they can turn into thunderstorms. The bottom of cumulus clouds are fairly close to the ground.\n\nStratus clouds look like flat sheets of clouds. These clouds can mean an overcast day or steady rain. They may stay in one place for several days.\n\nCirrus clouds are high feathery clouds. They are up so high they are actually made up of ice particles. They are indicators of fair weather when they are scattered in a clear blue sky.\n\nNimbus is another word associated with clouds. Adding "nimbus" means precipitation is falling from the cloud.\n\nCumulonimbus clouds are the "thunderheads" that can be seen on a warm summer day and can bring strong winds, hail, and rain.\n\nNimbostratus clouds will bring a long steady rain.

Clouds are water vapor. Think of it like a pocket of fog in the sky.

no clouds are not solid they are made  up of water  vapor and gas. Clouds are formed when air contains as much water vapor (gas) as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.\n\nIt should be noted that condensation by itself does not cause precipitation (rain, snow, sleet, hail). The moisture in clouds must become heavy enough to succumb to gravity and return to earth's surface. This occurs through two processes. In cold clouds ice crystals and water droplets exist side by side. Due to an imbalance of water vapor pressure, the water droplets transfer to the ice crystals. The crystal seventually grow heavy enough to fall to earth. In the second process, water droplets in warm clouds collide and change their electric charge.Droplets of unlike charge attract one another and merge, thereby growing until they have sufficient weight to fall.\n\nThere is no difference between fog and clouds other than altitude. Fog is defined as a visible moisture that begins at a height lower than 50 feet. If the visible moisture begins at or above 50 feet, it is called a cloud. Two common types of fog are called radiation fog and advection fog. Radiation fog forms during the night as the earth's surface cools and the air immediately above it cools in turn by conduction. If the air is moist enough, the cooling causes it to reach saturation and visible water droplets form. We often call this type of fog ground fog because it lies so close to the surface. Advection fog forms when warm moist air moves over a colder surface (advection means to move horizontally). A perfect example is on the west coast of continents. Prevailing westerly winds move moist air from over a warm ocean area to over the colder waters off the coast. Fog forms and is carried by the westerly over the land.\n\nClouds can form anywhere in the troposphere, and although condensed liquid, they are light enough to float in the air and move from place to place by the wind. Clouds are classified according to appearance and height. Based on appearance, there are two major types: Clouds of vertical development, formed by the condensation of rising air; and clouds that are layered, formed by condensation of air without vertical movement. When clouds are classified by height, there are four classes: high, middle, low, and vertical development.\n\nCloud names, of which there are twelve, combine appearance and height. A brief description of the root name will indicate this combination of features.

No.  The cloud will form when the ambient temperature inside the cloud is lower than the dew point.  The moisture may actually form snow (on a summer day!) which melts on the way down to form rain.  The temperature outside the cloud may be less relevant because clouds often form when a column of moisture-laden air rises locally condensing into a  cloud right above the column.

Water vapor is transparent (for most purposes) and so mere humidity in the atmosphere can't be a cloud. Since clouds don't have motors keeping them in the air, and yet stay there for hours in some cases, they can't be solid, for if they were, they'd fall out of the sky and we'd find cloud bits laying around on the ground. And the same is true for liquid as well. \n\nSo what's a cloud? Mostly, it's very small bits, so small that air currents can keep them in the air. The bits can be solid (eg, ice crystals of which snowflakes are examples), or liquid (eg, little drops of water, of which rain is an example). In either case, enough of these small things begin to look white as light passes thorough them and is reflected and refracted and generally diverted. Kind of like the effect of fine particulate suspensions in water. They are sometimes referred to as milky looking. Indeed, milk is white for a similar reason.\n\nThese are usually formed around dust bits, for real. High humidity (forced by cooling temperatures) produces supercooling (ie, ready to condense, if a trigger can be found). The dust motes provides the trigger. With updraft winds, a condensed drop can grow pretty large. And if it goes high enough, and gets cold enough, the drop can freeze (and thus make hail). If the orignal condensation is sufficiently cold, then water will be added to an ice crystal. With the proper history, such crystals become snowflakes.

Clouds are formed when warm moisture laden air is forced upwards either by a physical obstruction such as a hill/mountain or by being heated by the ground/sun.\nAs it rises it cools, and cold air can hold less moisture than warm air, so the vapour condenses out into droplets that form our clouds.\n\nFog is caused when moisture laden air is cooled by contact with the ground or water, it gets colder and colder until any moisture condenses out.  Fog forms as a layer as the air above it tends to be warmer due to rflected heat from the sun and also becauseof the lack of wind to stir the two layers together.  This is often referred to as an inversion.

Clouds are formed essentially by water vapours.The uppermost layer of waterbodies like sea,river,ponds etc(specially sea) are in the process of evaporation always.now water vapour is a gas and due to the fa that the surface of the waterbodies and the earth is hotter,the watervapour expands its volume.As you must be knowing density of an object is its mass divided by volume.Mass being constant,if volume increases density decreases and the water-vapour getting lighter goes up.There the temperature being less ,the water vapour condenses into water-droplets and floats as clouds,
