Meteorology Meteorology AccuWeather is a large American company that provides weather forecasting services. It was founded in 1962 by Dr. Joel N. Myers, then a Penn State graduate student working on degrees in meteorology, who was forecasting weather for a gas company in Pennsylvania. The company became officially known under the name "AccuWeather" in 1971. As well as running the company, Myers became a member of the school's faculty and taught many meteorologists, and AccuWeather is still headquartered in State College, Pennsylvania, the home of Penn State. ...more on Wikipedia about "AccuWeather"
The adiabatic lapse rate is the rate of temperature change that occurs in an atmosphere as a function of elevation, assuming that air behaves adiabatically. This term is most commonly used to refer to Earth's atmosphere. ...more on Wikipedia about "Adiabatic lapse rate"
Advection is the transport of a conserved scalar quantity that is transported in a vector field. A good example to have in mind would be the transport of pollution in a river: the motion of the water carries the polluted water downstream (see pigpen problem). ...more on Wikipedia about "Advection"
Aerography is the production of weather charts. The information is supplied by radiosonde observations, principally. Constant-pressure charts are routinely constructed at standard air pressures. Standard air pressures are 850, 700, 500, 400, 300, 250, and 200 millibars ( hectopascals) ( hPa) ( SI). Weather charts are sometimes drawn at lower air pressures that occur above 40,000 feet (12 km). The lines of equal air pressure are called isobars. Isotherms are the lines of equal air temperature. ...more on Wikipedia about "Aerography (meteorology)"

An air parcel is a meteorologically defined chunk of air in the atmosphere. Meteorologists study the movements and changes in air parcels over time as one tool in weather forecasting. ...more on Wikipedia about "Air parcel"
The airglow is the very weak emission of visible light by the earth's atmosphere, which means that the night sky is never completely dark. It was first noticed in 1868 by Anders Ångström. It is caused by various processes in the upper atmosphere, such as the recombination of ions which were photoionised by the sun during the day, luminescence caused by cosmic rays striking the upper atmosphere, and chemiluminescence caused mainly by oxygen and nitrogen reacting with hydroxyl ions at heights of a few hundred kilometres. It is not noticeable during the daytime because of the scattered light from the Sun. ...more on Wikipedia about "Airglow"
AMeDAS (Automated Meteorological Data Acquisition System), commonly known in Japanese as "アメダス" (amedasu), is a high-resolution surface observation network developed by Japan Meteorological Agency (JMA) used for gathering regional weather data and verifying forecast performance. Begun operation on November 1, 1974, the system consists of about 1,300 stations with automatic observation equipment. These stations, of which more than 1,100 are unmanned, are located at an average interval of 17 km throughout Japan. ...more on Wikipedia about "AMeDAS"
The American Meteorological Society promotes the development and dissemination of information and education on the atmospheric and related oceanic and hydrologic sciences and the advancement of their professional applications. Founded in 1919, AMS has a membership of more than 11 000 professionals, professors, students, and weather enthusiasts. AMS publishes nine atmospheric and related oceanic and hydrologic journals — in print and online — sponsors more than 12 conferences annually, and offers numerous programs and services. ...more on Wikipedia about "American Meteorological Society"
An anemometer is a device for measuring the velocity or the pressure of the wind, and is one instrument used in a weather station. The term is derived from the Greek word "anemos" meaning wind. ...more on Wikipedia about "Anemometer"

Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth's atmosphere and that of other planets is studied. It is a multidisciplinary field of research and draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology and other disciplines. Research is increasingly connected with other areas of study such as climatology. ...more on Wikipedia about "Atmospheric chemistry"
Atmospheric physics is the application of physics to the study of the atmosphere. Atmospheric physicists attempt to model Earth's atmosphere and the atmospheres of the other planets using fluid flow equations, chemical models, radiation balancing, and energy transfer processes in the atmosphere (as well as how these tie in to other systems such as the oceans). In order to model weather systems, atmospheric physicists employ elements of scattering theory, wave propagation models, cloud physics, statistical mechanics and spatial statistics which are highly mathematical and related to physics. ...more on Wikipedia about "Atmospheric physics"
Atmospheric pressure is the pressure above any area in the Earth's atmosphere caused by the weight of air. Standard atmospheric pressure (atm) is discussed in the next section. ...more on Wikipedia about "Atmospheric pressure"
Atmospheric stratification is the division of the atmosphere into distinct layers, each with specific properties such as temperature or humidity. ...more on Wikipedia about "Atmospheric stratification"
An atmospheric wave is a periodic disturbance in the fields of atmospheric variables (like surface pressure or geopotential height, temperature, or wind velocity) which may either propagate (traveling wave) or not (stationary wave). Atmospheric waves range in spatial and temporal scale from large-scale planetary waves ( Rossby waves) to minute sound waves. ...more on Wikipedia about "Atmospheric wave"
The Automated Surface Observing System (ASOS) and the older Automated Weather Observing System (AWOS) are sensors used to measure and record hourly and significant weather conditions at airports across the United States. The newer Automated Weather Sensor System (AWSS) is the successor to AWOS, reporting once per minute. ASOS units are implemented cooperatively, with the National Weather Service operating them and the Federal Aviation Administration (FAA) distributing information to pilots. AWOS and AWSS units are operated and controlled by the FAA; the NWS plays no role in their operation or deployment. Data dissemination is usually via an automated VHF airband radio frequency (118~136MHz) at each airport, broadcasting ASOS or AWOS weather information, often via the Automatic Terminal Information Service (ATIS). ...more on Wikipedia about "Automated Surface Observing System"

The Bulk Richardson Number is a dimensionless number in meteorology relating vertical stability and vertical shear (generally, stability divided by shear). High values indicate unstable and/or weakly-sheared environments; low values indicate weak instability and/or strong vertical shear. Generally, values in the range of around 50 to 100 suggest environmental conditions favorable for supercell development. ...more on Wikipedia about "Bulk Richardson number"
Buys-Ballot's law, in meteorology, is the name given to a law which may be expressed as follows: In the Northern Hemisphere, stand with your back to the wind; the low pressure area will be on your left. In other words, wind travels counterclockwise around low pressure zones in the Northern Hemisphere. It is approximately true in the higher latitudes of the Northern Hemisphere, and is reversed in the Southern Hemisphere, but the angle between barometric gradient and wind is not a right angle in low latitudes. See Coriolis_effect#Flow_around_a_low-pressure_area. ...more on Wikipedia about "Buys-Ballot's law"
The Caribbean Meteorological Institute was established in 1967 by the member states of the Caribbean Meteorological Organisation (CMO). It was amalgamated with the Caribbean Operational Hydrological Institute (COHI) in the mid-1980s to form the Caribbean Institute for Meteorology and Hydrology (CIMH), but the name was only officially changed in September 1999 to reflect the dual role of the Institute. Responsibility for the operation of the Institute, which is located in Barbados, rests with the sixteen Commonwealth Governments which comprise the CMO. ...more on Wikipedia about "Caribbean Meteorological Institute" The text you are reading is from shortopedia
