Weather is described in terms of variable conditions such as temperature, humidity, wind velocity, precipitation, and barometric pressure. Weather on Earth occurs primarily in the troposphere, or lower atmosphere, and is driven by energy from the Sun and the rotation of the Earth.

weather - the atmospheric conditions that comprise the state of the atmosphere in terms of temperature and wind and clouds and precipitation; "they were hoping for good weather"; "every day we have weather conditions and yesterday was no exception"; "the conditions were too . the conditions in the air above the earth such as wind, rain, or temperature, especially at a particular time over a particular area: bad /good/ cold / dry / hot / stormy / warm / wet /etc. weather The weather .

Weather is the state of the atmosphere , describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy.

Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. Weather is driven by air pressure , temperature , and moisture differences between one place and another.

These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations : the Hadley cell , the Ferrel cell , the polar cell , and the jet stream. Weather systems in the middle latitudes , such as extratropical cyclones , are caused by instabilities of the jet streamflow. Because Earth's axis is tilted relative to its orbital plane called the ecliptic , sunlight is incident at different angles at different times of the year.

Over thousands of years, changes in Earth's orbit can affect the amount and distribution of solar energy received by Earth, thus influencing long-term climate and global climate change. Surface temperature differences in turn cause pressure differences. Higher altitudes are cooler than lower altitudes, as most atmospheric heating is due to contact with the Earth's surface while radiative losses to space are mostly constant. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location.

Earth's weather system is a chaotic system ; as a result, small changes to one part of the system can grow to have large effects on the system as a whole.

Human attempts to control the weather have occurred throughout history, and there is evidence that human activities such as agriculture and industry have modified weather patterns. Studying how the weather works on other planets has been helpful in understanding how weather works on Earth.

A famous landmark in the Solar System , Jupiter 's Great Red Spot , is an Anticyclonic storm known to have existed for at least years. However, the weather is not limited to planetary bodies.

A star's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. The movement of mass ejected from the Sun is known as the solar wind. On Earth , the common weather phenomena include wind, cloud , rain, snow, fog and dust storms.

Less common events include natural disasters such as tornadoes , hurricanes , typhoons and ice storms. Almost all familiar weather phenomena occur in the troposphere the lower part of the atmosphere.

Weather occurs primarily due to air pressure, temperature and moisture differences between one place to another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. In other words, the farther from the tropics one lies, the lower the sun angle is, which causes those locations to be cooler due to the spread of the sunlight over a greater surface. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year.

In June the Northern Hemisphere is tilted towards the sun , so at any given Northern Hemisphere latitude sunlight falls more directly on that spot than in December see Effect of sun angle on climate. Over thousands to hundreds of thousands of years, changes in Earth's orbital parameters affect the amount and distribution of solar energy received by the Earth and influence long-term climate.

See Milankovitch cycles. The uneven solar heating the formation of zones of temperature and moisture gradients, or frontogenesis can also be due to the weather itself in the form of cloudiness and precipitation. This phenomenon is known as an inversion and can cause mountaintops to be warmer than the valleys below. Inversions can lead to the formation of fog and often act as a cap that suppresses thunderstorm development. On local scales, temperature differences can occur because different surfaces such as oceans, forests, ice sheets, or man-made objects have differing physical characteristics such as reflectivity , roughness, or moisture content.

A hot surface warms the air above it causing it to expand and lower the density and the resulting surface air pressure. Large scale examples include the Hadley cell while a smaller scale example would be coastal breezes.

The atmosphere is a chaotic system. As a result, small changes to one part of the system can accumulate and magnify to cause large effects on the system as a whole. However, it is theoretically impossible to make useful day-to-day predictions more than about two weeks ahead, imposing an upper limit to potential for improved prediction skill.

Weather is one of the fundamental processes that shape the Earth. The process of weathering breaks down the rocks and soils into smaller fragments and then into their constituent substances. This causes the rainwater to be slightly acidic, which aids the erosive properties of water. The sediment may reform in time and by geological forces into other rocks and soils.

In this way, weather plays a major role in erosion of the surface. Weather, seen from an anthropological perspective, is something all humans in the world constantly experience through their senses, at least while being outside. There are socially and scientifically constructed understandings of what weather is, what makes it change, the effect it has on humans in different situations, etc.

The National Weather Service has an annual report for fatalities, injury, and total damage costs which include crop and property. As of , tornadoes have had the greatest impact on humans with 42 fatalities while costing crop and property damage over 3 billion dollars. The weather has played a large and sometimes direct part in human history.

Aside from climatic changes that have caused the gradual drift of populations for example the desertification of the Middle East, and the formation of land bridges during glacial periods , extreme weather events have caused smaller scale population movements and intruded directly in historical events. One such event is the saving of Japan from invasion by the Mongol fleet of Kublai Khan by the Kamikaze winds in The Little Ice Age caused crop failures and famines in Europe.

The s saw the worst famine in France since the Middle Ages. Finland suffered a severe famine in —, during which about one-third of the Finnish population died. Human beings have attempted to predict the weather informally for millennia, and formally since at least the nineteenth century.

Once an all-human endeavor based mainly upon changes in barometric pressure , current weather conditions, and sky condition, [30] [31] forecast models are now used to determine future conditions.

On the other hand, human input is still required to pick the best possible forecast model to base the forecast upon, which involve many disciplines such as pattern recognition skills, teleconnections , knowledge of model performance, and knowledge of model biases. The chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, the error involved in measuring the initial conditions, and an incomplete understanding of atmospheric processes mean that forecasts become less accurate as of the difference in current time and the time for which the forecast is being made the range of the forecast increases.

The use of ensembles and model consensus helps to narrow the error and pick the most likely outcome. There are a variety of end users to weather forecasts. Weather warnings are important forecasts because they are used to protect life and property. Temperature forecasts are used by utility companies to estimate demand over coming days.

In some areas, people use weather forecasts to determine what to wear on a given day. Since outdoor activities are severely curtailed by heavy rain , snow and the wind chill , forecasts can be used to plan activities around these events and to plan ahead to survive through them. Tropical weather forecasting is different from that at higher latitudes. The sun shines more directly on the tropics than on higher latitudes at least in the average over a year , which makes the tropics warm Stevens And, the vertical direction up, as one stands on the Earth's surface is perpendicular to the Earth's axis of rotation at the equator, while the axis of rotation and the vertical are the same at the pole; this causes the Earth's rotation to influence the atmospheric circulation more strongly at high latitudes than low.

Because of these two factors, clouds and rainstorms in the tropics can occur more spontaneously compared to those at higher latitudes, where they are more tightly controlled by larger-scale forces in the atmosphere. Because of these differences, clouds and rain are more difficult to forecast in the tropics than at higher latitudes. On the other hand, the temperature is easily forecast in the tropics, because it doesn't change much. The aspiration to control the weather is evident throughout human history: from ancient rituals intended to bring rain for crops to the U.

Military Operation Popeye , an attempt to disrupt supply lines by lengthening the North Vietnamese monsoon. The most successful attempts at influencing weather involve cloud seeding ; they include the fog - and low stratus dispersion techniques employed by major airports, techniques used to increase winter precipitation over mountains, and techniques to suppress hail.

China shot 1, rain dispersal rockets from 21 sites in the city of Beijing in an effort to keep rain away from the opening ceremony of the games on 8 August Whereas there is inconclusive evidence for these techniques' efficacy, there is extensive evidence that human activity such as agriculture and industry results in inadvertent weather modification: [45]. The effects of inadvertent weather modification may pose serious threats to many aspects of civilization, including ecosystems , natural resources , food and fiber production, economic development , and human health.

Microscale meteorology is the study of short-lived atmospheric phenomena smaller than mesoscale , about 1 km or less. These two branches of meteorology are sometimes grouped together as "mesoscale and microscale meteorology" MMM and together study all phenomena smaller than synoptic scale ; that is they study features generally too small to be depicted on a weather map. These include small and generally fleeting cloud "puffs" and other small cloud features.

The range of climates and latitudes across the planet can offer extremes of temperature outside this range. The hottest air temperature ever recorded was The highest recorded average annual temperature was It was recorded as 31, mm Studying how the weather works on other planets has been seen as helpful in understanding how it works on Earth.

The Cassini—Huygens mission to Titan discovered clouds formed from methane or ethane which deposit rain composed of liquid methane and other organic compounds. One of the most famous landmarks in the Solar System , Jupiter 's Great Red Spot , is an anticyclonic storm known to have existed for at least years.

Weather is not limited to planetary bodies. Like all stars, the Sun's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. Inconsistencies in this wind and larger events on the surface of the star, such as coronal mass ejections , form a system that has features analogous to conventional weather systems such as pressure and wind and is generally known as space weather.

Coronal mass ejections have been tracked as far out in the Solar System as Saturn. The interaction of the solar wind with the terrestrial atmosphere can produce spectacular aurorae , [67] and can play havoc with electrically sensitive systems such as electricity grids and radio signals.
