Atmospheric physics Atmospheric dynamics category. Climate category Climate change category. Meteorology is a branch of the atmospheric sciences which includes atmospheric chemistry and atmospheric physics , with a major focus on weather forecasting. The study of meteorology dates back millennia , though significant progress in meteorology did not occur until the 18th century.
The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics and more particularly, the development of the computer, allowing for the automated solution of a great many equations that model the weather, in the latter half of the 20th century that significant breakthroughs in weather forecasting were achieved.
An important domain of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water. Meteorological phenomena are observable weather events that are explained by the science of meteorology. Meteorological phenomena are described and quantified by the variables of Earth's atmosphere : temperature , air pressure , water vapour , mass flow , and the variations and interactions of those variables, and how they change over time.
Different spatial scales are used to describe and predict weather on local, regional, and global levels. Meteorology, climatology , atmospheric physics , and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Meteorology and hydrology compose the interdisciplinary field of hydrometeorology.
The interactions between Earth's atmosphere and its oceans are part of a coupled ocean-atmosphere system. Meteorology has application in many diverse fields such as the military , energy production , transport , agriculture , and construction.
The ability to predict rains and floods based on annual cycles was evidently used by humans at least from the time of agricultural settlement if not earlier. Early approaches to predicting weather were based on astrology and were practiced by priests. Cuneiform inscriptions on Babylonian tablets included associations between thunder and rain.
Ancient Indian Upanishads contain mentions of clouds and seasons. In BC, Aristotle wrote Meteorology. The Greek scientist Theophrastus compiled a book on weather forecasting, called the Book of Signs. The work of Theophrastus remained a dominant influence in the study of weather and in weather forecasting for nearly 2, years. He describes the meteorological character of the sky, the planets and constellations , the sun and moon , the lunar phases indicating seasons and rain, the anwa heavenly bodies of rain , and atmospheric phenomena such as winds, thunder, lightning, snow, floods, valleys, rivers, lakes.
Early attempts at predicting weather were often related to prophecy and divining, and were sometimes based on astrological ideas. Admiral FitzRoy tried to separate scientific approaches from prophetic ones. Ptolemy wrote on the atmospheric refraction of light in the context of astronomical observations.
Albert the Great was the first to propose that each drop of falling rain had the form of a small sphere, and that this form meant that the rainbow was produced by light interacting with each raindrop.
He stated that a rainbow summit can not appear higher than 42 degrees above the horizon. Theoderic went further and also explained the secondary rainbow. In , Leone Battista Alberti developed a swinging-plate anemometer , and was known as the first anemometer.
In , Gabriel Fahrenheit created a reliable scale for measuring temperature with a mercury-type thermometer. The April launch of the first successful weather satellite , TIROS-1 , marked the beginning of the age where weather information became available globally. In , Blaise Pascal rediscovered that atmospheric pressure decreases with height, and deduced that there is a vacuum above the atmosphere. In , Black's student Daniel Rutherford discovered nitrogen , which he called phlogisticated air , and together they developed the phlogiston theory.
In , John Dalton defended caloric theory in A New System of Chemistry and described how it combines with matter, especially gases; he proposed that the heat capacity of gases varies inversely with atomic weight.
In , Sadi Carnot analyzed the efficiency of steam engines using caloric theory; he developed the notion of a reversible process and, in postulating that no such thing exists in nature, laid the foundation for the second law of thermodynamics.
In , Christopher Columbus experienced a tropical cyclone, which led to the first written European account of a hurricane. Gaspard-Gustave Coriolis published a paper in on the energy yield of machines with rotating parts, such as waterwheels.
By , this deflecting force was named the Coriolis effect. In the late 16th century and first half of the 17th century a range of meteorological instruments were invented — the thermometer , barometer , hydrometer , as well as wind and rain gauges. In the s natural philosophers started using these instruments to systematically record weather observations. Scientific academies established weather diaries and organised observational networks. The collected data were sent to Florence at regular time intervals.
Hippocrates ' treatise Airs, Waters, and Places had linked weather to disease. Thus early meteorologists attempted to correlate weather patterns with epidemic outbreaks, and the climate with public health. During the Age of Enlightenment meteorology tried to rationalise traditional weather lore, including astrological meteorology.
But there were also attempts to establish a theoretical understanding of weather phenomena. Edmond Halley and George Hadley tried to explain trade winds. They reasoned that the rising mass of heated equator air is replaced by an inflow of cooler air from high latitudes. A flow of warm air at high altitude from equator to poles in turn established an early picture of circulation. Frustration with the lack of discipline among weather observers, and the poor quality of the instruments, led the early modern nation states to organise large observation networks.
Thus by the end of the 18th century, meteorologists had access to large quantities of reliable weather data. This data could be used to produce maps of the state of the atmosphere for a region near the Earth's surface and to study how these states evolved through time. To make frequent weather forecasts based on these data required a reliable network of observations, but it was not until that the Smithsonian Institution began to establish an observation network across the United States under the leadership of Joseph Henry.
FitzRoy's office became the United Kingdom Meteorological Office in , the second oldest national meteorological service in the world the Central Institution for Meteorology and Geodynamics ZAMG in Austria was founded in and is the oldest weather service in the world. The first daily weather forecasts made by FitzRoy's Office were published in The Times newspaper in The following year a system was introduced of hoisting storm warning cones at principal ports when a gale was expected.
Over the next 50 years, many countries established national meteorological services. The India Meteorological Department was established to follow tropical cyclone and monsoon. The Australian Bureau of Meteorology was established by a Meteorology Act to unify existing state meteorological services. In , Norwegian scientist Vilhelm Bjerknes first argued in his paper Weather Forecasting as a Problem in Mechanics and Physics that it should be possible to forecast weather from calculations based upon natural laws.
It was not until later in the 20th century that advances in the understanding of atmospheric physics led to the foundation of modern numerical weather prediction. He described how small terms in the prognostic fluid dynamics equations that govern atmospheric flow could be neglected, and a numerical calculation scheme that could be devised to allow predictions.
Richardson envisioned a large auditorium of thousands of people performing the calculations. However, the sheer number of calculations required was too large to complete without electronic computers, and the size of the grid and time steps used in the calculations led to unrealistic results. Though numerical analysis later found that this was due to numerical instability.
Starting in the s, numerical forecasts with computers became feasible. In the s, the chaotic nature of the atmosphere was first observed and mathematically described by Edward Lorenz , founding the field of chaos theory. These climate models are used to investigate long-term climate shifts, such as what effects might be caused by human emission of greenhouse gases.
Meteorologists are scientists who study and work in the field of meteorology. In the United States, meteorologists held about 10, jobs in Although weather forecasts and warnings are the best known products of meteorologists for the public, weather presenters on radio and television are not necessarily professional meteorologists. They are most often reporters with little formal meteorological training, using unregulated titles such as weather specialist or weatherman.
The American Meteorological Society and National Weather Association issue "Seals of Approval" to weather broadcasters who meet certain requirements but this is not mandatory to be hired by the medias. Each science has its own unique sets of laboratory equipment.
In the atmosphere, there are many things or qualities of the atmosphere that can be measured. Rain, which can be observed, or seen anywhere and anytime was one of the first atmospheric qualities measured historically.
Also, two other accurately measured qualities are wind and humidity. Neither of these can be seen but can be felt. The devices to measure these three sprang up in the midth century and were respectively the rain gauge , the anemometer, and the hygrometer.
Many attempts had been made prior to the 15th century to construct adequate equipment to measure the many atmospheric variables. Many were faulty in some way or were simply not reliable.
Even Aristotle noted this in some of his work as the difficulty to measure the air. Sets of surface measurements are important data to meteorologists. They give a snapshot of a variety of weather conditions at one single location and are usually at a weather station , a ship or a weather buoy. The measurements taken at a weather station can include any number of atmospheric observables. Usually, temperature, pressure , wind measurements, and humidity are the variables that are measured by a thermometer, barometer, anemometer, and hygrometer, respectively.
Upper air data are of crucial importance for weather forecasting. The most widely used technique is launches of radiosondes. Supplementing the radiosondes a network of aircraft collection is organized by the World Meteorological Organization. Remote sensing , as used in meteorology, is the concept of collecting data from remote weather events and subsequently producing weather information. The common types of remote sensing are Radar , Lidar , and satellites or photogrammetry.
Each collects data about the atmosphere from a remote location and, usually, stores the data where the instrument is located. Radar and Lidar are not passive because both use EM radiation to illuminate a specific portion of the atmosphere. The study of the atmosphere can be divided into distinct areas that depend on both time and spatial scales.
At one extreme of this scale is climatology. In the timescales of hours to days, meteorology separates into micro-, meso-, and synoptic scale meteorology. Respectively, the geospatial size of each of these three scales relates directly with the appropriate timescale.
Other subclassifications are used to describe the unique, local, or broad effects within those subclasses.

Сьюзан, чуть подтолкнув, усадила его на место. - Нет! - рявкнула. - Пойду я! - Ее тон говорил о том, что возражений она не потерпит. Стратмор закрыл лицо руками. - Хорошо.
Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна.
Но их пальцы не встретились. Из темноты раздался протяжный вопль, и тут же, словно из-под земли, выросла громадная фигура, эдакий грузовик, несущийся на полной скорости с выключенными фарами. Секундой позже произошло столкновение, и Стратмор, сбитый с ног, кубарем покатился по кафельному полу шифровалки.
