WIND \nAir that flows in relation to the earth's surface, generally horizontally. There are four areas of wind that are measured: direction, speed, character (gusts and squalls), and shifts. Surface winds are measured by wind vanes and anemometers, while upper level winds are detected through pilot balloons, rawin, or aircraft reports. \nWhoosh! You know that wind is moving air. But what causes the air to move? It’s the uneven heating of the earth’s atmosphere. \n\nAs the sun warms the earth’s surface, the atmosphere warms too. Some parts of the earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air, which weighs less than cool air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.

Storms are created when a center of low pressure develops, with a system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds, such as the cumulonimbus. Small, localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds.

What causes rain to turn into sleet? when it's raining and there is a layer of very cold air in the atmosphere, usually 32 or below, it will turn into frozen precipitation, whether is Snow, sleet. when it snows, the whole atmosphere is at 32 or below, even though your temp at ground is let's say 35. what's matter is the atmosphere temperature. when it sleets, there's got to be a layer of cold air 32 or below, then another layer of 32 or hight ( that's when it turns back into rain) and then, another layer of cold air just above ground level or tree height, that's when you get the sleet.

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.

Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect).\n\nGiven a difference in barometric pressure between two air masses, a wind will arise between the two which tends to flow from the area of high pressure to the area of low pressure until the two air masses are at the same pressure, although these flows will be modified by the Coriolis effect in the extratropics.\n\nWinds can be classified either by their scale, the kinds of forces which cause them (according to the atmospheric equations of motion), or the geographic regions in which they exist. There are global winds, such as the wind belts which exist between the atmospheric circulation cells. There are upper-level winds, such as the jet streams. There are synoptic-scale winds that result from pressure differences in surface air masses in the middle latitudes, and there are winds that come about as a consequence of geographic features such as the sea breeze. Mesoscale winds are those which act on a local scale, such as gust fronts. At the smallest scale are the microscale winds which blow on a scale of only tens to hundreds of metres and are essentially unpredictable, such as dust devils and microbursts.\n\nYou could get more information from the link below...

This is not always the case.  The phenomenon you speak of is most associated with cumulus clouds, those you see most in the  spring, summer, and fall, and which also produce the most weather (including tornadoes and the main source of hurricanes).  Cirrus and stratus clouds are generally quite flat or layered in structure and are responsible for most overcast days.  Most aren't very fluffy, though high winds aloft can sometimes cause them to take some pretty interesting shapes.\nCumulus are the "cauliflower" like clouds that form when air from below rises rapidly because its unstable.  Air is unstable when it is warmer than air around it.\nCumulus form when the ground heats up during the day causing the air near it to become unstable or when some "forcing" mechanism like a front causes lift.  The flat base forms when the air rising from below reaches saturation (air cools as it rises, and thus the relative humidity increases until it reaches about 100% when the cloud begins to form).    Because the source air for the cloud is all of about the same moisture and temperature, all of the rising air reaches saturation at the same level (termed the Lifted Condensation Level (LCL), when the air starts rising very near the ground).\n\nBecause the air is still unstable, it continues to rise.  That's why you get these large "towers" that build up, and the quicker they rise, the stronger the storm they produce.  As the air continues to rise, it begins to mix with the surrounding environment and above a certain level (the Equilibrium Level, EL) the air becomes stable (cooler than the environment).  Different pockets of air continue to rise  at different rates, and that causes the fluffy nature nearer the top of these clouds.\n\nCumulus are different from stratus and cirrus because they indicate large vertical motion and have a very distinct structure to them.\n\nBasically you could even think of a cumulus cloud as like blowing a balloon upwards.  The bottom is all at one defined spot, while as the air moves into the balloon, it spreads out.  In a cloud the rising air also mixes in different proportions with the environmental air, causing the unique shapes higher up in the cloud.  Hope that helped.  If it's not clear, let me know! :-)

It all depends upon the layers of temparature in the atmosphere.  If an upper layer where the precipitation originates is below freezing then it can snow even if it is above freezing at ground level.  Reverse those temperatures and you get freezing rain.

There are in fact many different atmospheric layers as you move upward away from the earth. However, there are NOT different layers of gases. All the gases are sort of mixed.\n\nThe troposphere, the atmospheric layer that we live in, contains the most gases. This is due to gravity. Anything that has mass will be attracted to earth's gravity.\n\nThat is why when you move away from the earth there is less air. Less gravity = less air!\n\nThe higher you go in the troposphere, the colder it gets. That is also due to less air (holds heat).\n\nThe next layer up is the stratosphere. This layer is where most jets fly & where the atmospheric ozone layer exists.\n\nTemperatures in the stratosphere will get warmer due to the ozone layer. Ozone is an insulator & traps heat.\n\nAs you move higher, you will reach the mesosphere. And, as you may have already guessed, this layer contains even less air. It also gets pretty darn cold as you move away from the ozone layer. "Shooting stars" occur in this layer. Meteorites burn up as they enter our atmosphere.\n\nThe last layer is called the thermosphere. It has the least amount of air. But the odd thing is that this is the hottest layer!!!\n\nSounds strange??? Well here is why...\n\nAlthough there is less air to hold heat, there is still some present. Mind you, it is few & far between. Imagine being in the Astrodome & someone across the field threw a BB at you! That is how sparse the air particles are.\n\nHowever, we have said there is air! That air that is present is constantly bombarded with nasty cosmic rays! By this time, here is so much energy in the air particles that the temperature is astronomical (no pun intended).\n\nBecause of this, the thermosphere is often called the "heat sphere", just as it's name implies.\n\nSatellites are put into orbit in the thermosphere.\n\nTo get directly to your question... there are different layers because scientists decided to name them according to temperature changes.

On Earth dust occurs in the atmosphere from various sources: soil dust lifted up by wind, volcanic eruptions, and pollution are some examples.

Temperature decreases as altitude increases-the temperature of the atmosphere is coupled to the temperature of the ground by convection. Warm air rises and carries heat.\nAs it expands, it cools, leading to a decrease in temperature with altitude. This occurs in the troposphere, where most of the earth's weather happens.\nThis occurs in the troposphere, where most of the earth's weather happens. Once past the tropopause, where the troposphere ends and the stratosphere begins, it's a whole different ballgame.

Their climate causes tornadoes. When a hot and cold front meet, it creates a storm that can lead to a tornado. Tornadoes are caused by warm weather.

Stratosphere\nThe stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Compared to the troposphere, this part of the atmosphere is dry and less dense. The temperature in this region increases gradually to -3 degrees Celsius, due to the absorbtion of ultraviolet radiation. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. Ninety-nine percent of "air" is located in the troposphere and stratosphere. The stratopause separates the stratosphere from the next layer.\n\nMesosphere\nThe mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high. In this region, the temperatures again fall as low as -93 degrees Celsius as you increase in altitude. The chemicals are in an excited state, as they absorb energy from the Sun. The mesopause separates the mesophere from the thermosphere.\n\nThe regions of the stratosphere and the mesosphere, along with the stratopause and mesopause, are called the middle atmosphere by scientists. This area has been closely studied on the ATLAS Spacelab mission series.

Like all matter, the atmosphere is heated by the suns light.  When light is absorbed by the earth (the ground, the ocean, etc.) it is heated up (it's molecules move around faster) The air that makes up the atmosphere then absorbs some of the heat that is emitted by the earth.  When the air absorbs heat from the earth, this cools the earth.
