"Climatology Climatology (from Greek , ""klima"", ""place, zone""; and , ""-logia"") or climate science is the scientific study of climate, scientifically defined as weather conditions averaged over a period of time. This modern field of study is regarded as a branch of the atmospheric sciences and a subfield of physical geography, which is one of the Earth sciences. Climatology now includes aspects of oceanography and biogeochemistry. Basic knowledge of climate can be used within shorter term weather forecasting using analog techniques such as the El Niño–Southern Oscillation (ENSO), the Madden–Julian oscillation (MJO), the North Atlantic oscillation (NAO), the Northern Annular"

Weather is the condition of the atmosphere at a particular place over a short period of time, whereas climate refers to the weather pattern, using statistical data, of a place over a long enough period to yield meaningful averages. Meteorology studies weather, while climatology studies climate; both are atmospheric sciences. Climate is an important physical element because it indicates the atmospheric condition of heat, moisture and circulation; it plays a dominant role in shaping vegetation and soil; and it ultimately"

Astrometeorology is thousands of years old and based on astronomical positions that allegedly directly affect the weather on Earth. Ancient classical astrologers created weather forecasting known as meteorology by noting the positions of stars, planets, the Sun, and Moon. According to their texts, when planets occupy constellations as seen from Earth, and that are harmonious to one another, or"
"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. Most weather phenomena occur in the lowest level of the atmosphere, the troposphere, just below the stratosphere. 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. When used without qualification, ""weather"" is generally understood to mean the weather of Earth. Weather is driven by air pressure, temperature and moisture differences between one place and another. These"

"Weather forecasting Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using meteorology to project how the atmosphere will change. Once calculated by hand based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric"
"Earth rainfall climatology Earth rainfall climatology Is the study of rainfall, a sub-field of Meteorology. Formally, a wider study includes water falling as ice crystals, i.e. hail, sleet, snow (parts of the hydrological cycle known as precipitation). The aim of rainfall climatology is to measure, understand and predict rain distribution across different regions of planet Earth, a factor of air pressure, humidity, topography, cloud type and raindrop size, via direct measurement and remote sensing data acquisition. Current technologies accurately predict rainfall 3–4 days in advance using numerical weather prediction. Geostationary orbiting satellites gather IR and visual wavelength data to measure"

Meteorology has application in many diverse fields such as the military, energy production, transport, agriculture, and construction. The word ""meteorology"" is from the Ancient Greek μετέωρος ""metéōros"" (""meteor"") and -λογία ""-logia"" (""-(o)logy""), meaning ""the study of things high in the air"". 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"
"Forensic meteorology Forensic meteorology is meteorology, the scientific study of weather, applied to the process of reconstructing weather events for a certain time and location. This is done by acquiring and analyzing local weather reports such as surface observations, radar and satellite images, other data, and eyewitness accounts. Forensic meteorology is most often used in court cases, including insurance disputes, personal injury cases, and murder investigations. With increasing losses from severe weather in recent years, the demand for forensic meteorological services has also grown. In the US, many forensic meteorologists are certified by the American Meteorological Society (AMS)'s rigorous Certified"
"Polar meteorology Polar meteorology is the study of the atmosphere of Earth's polar regions. Surface temperature inversion is typical of polar environments and leads to the katabatic wind phenomenon. The vertical temperature structure of polar environments tends to be more complex than in mid-latitude or tropical climates. The collection of polar meteorology data started in 1893 with Fridtjof Nansen during his North Pole expedition. One of the goals of the expedition was to make detailed meteorological and early oceanographic measurements. The measurements made from Nansen’s ship, which was named Fram, were used by Vagn Walfrid Ekman to develop the theory"
"For example, Aridisols have been redefined (Soil Survey Staff 1998) as soils that possess a calcic horizon of less than 1 meter in depth. The terms climate and weather are sometimes used interchangeably in modern languages, but have very different scientific meanings. Weather is the record of temperature, rainfall, and humidity as reported daily online, by newspapers, and by television. Conversely, climate is the average of data collected from weather reports, usually over a 30-year period, that reflects these observations. The weather data used to determine climate is based on particular weather stations that are generally chosen to reflect the"

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"
"Atmospheric thermodynamics Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the earth's atmosphere and manifest as weather or climate. Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and vertical instabilities in the atmosphere. Atmospheric thermodynamic diagrams are used as tools in the forecasting of storm development. Atmospheric thermodynamics forms a basis for cloud microphysics and convection parameterizations used in numerical weather models and is used in many climate considerations, including convective-equilibrium climate"

"Meteorological intelligence Meteorological intelligence is information measured, gathered, compiled, exploited, analyzed and disseminated by meteorologists, climatologists and hydrologists to characterize the current state and/or predict the future state of the atmosphere at a given location and time. Meteorological intelligence is a subset of environmental intelligence and is synonymous with the term weather intelligence. The earliest known use of the term ""meteorological intelligence"" in a written document dates to 1854 on pg. 168 of the Eighth Annual Report of the Board of Regents of the Smithsonian Institution. This report discusses the Smithsonian Institution's initiative to transmit meteorological intelligence via telegraph lines."
"clouds from which precipitation fell were called meteors, which originate from the Greek word ""meteoros"", meaning 'high in the sky'. From that word came the modern term meteorology, the study of clouds and weather. Meteorologica was based on intuition and simple observation, but not on what is now considered the scientific method. Nevertheless, it was the first known work that attempted to treat a broad range of meteorological topics. After centuries of speculative theories about the formation and behavior of clouds, the first truly scientific studies were undertaken by Luke Howard in England and Jean-Baptiste Lamarck in France. Howard was"

The first distinct climate treaties were the works of Hippocrates, who wrote Airs, Water and Places in 400 B.C.E. Climatology is approached in various ways such as Paleoclimatology, which seeks to reconstruct past climates by examining records such as ice cores and tree rings (dendroclimatology). Paleotempestology uses these same records to help determine hurricane frequency over millennia. The study of contemporary climates incorporates meteorological data accumulated over many years, such as records of rainfall, temperature"
"Cloud formation and climate change Nephology (; from the Greek word ""nephos"" for 'cloud') is the study of clouds and cloud formation. British meteorologist Luke Howard was a major researcher within this field, establishing a cloud classification system. While this branch of meteorology still exists today, the term nephology, or nephologist is rarely used. The term came into use at the end of the nineteenth century, and fell out of common use by the middle of the twentieth. Recently, interest in nephology (if not the name) has surged as many meteorologists have begun to focus on the relationship between clouds"

"Biometeorology Biometeorology is the interdisciplinary field of science that studies the interactions between the biosphere and the Earth's atmosphere on time scales of the order of seasons or shorter (by opposition to bioclimatology). Weather events influence biological processes on short time scales. For instance, as the Sun rises above the horizon in the morning, light levels become sufficient for the process of photosynthesis to take place in plant leaves. Later on, during the day, air temperature and humidity may induce the partial or total closure of the stomata, a typical response of many plants to limit the loss of water"
