Meteorology

Terra (EOS AM-1) is a multi-national NASA scientific research satellite in a Sun-synchronous orbit around the Earth.

BBC Weather is the BBC's department in charge of preparing and broadcasting weather forecasts and is now part of BBC News.

A general circulation model (GCM) is a type of climate model.

An atmospheric sounding is a measurement of vertical distribution of physical properties of the atmospheric column such as pressure, temperature, wind speed and wind direction (thus deriving wind shear), liquid water content, ozone concentration, pollution, and other properties.

The Aeronomy of Ice in the Mesosphere (AIM) is a satellite to conduct a 26-month study of noctilucent clouds (NLCs).

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location.

The Atlantic Multidecadal Oscillation (AMO) is an ocean current that is thought to affect the sea surface temperature of the North Atlantic Ocean based on different modes on multidecadal timescales.

A station model is a symbolic illustration showing the weather occurring at a given reporting station.

Aura (EOS CH-1) is a multi-national NASA scientific research satellite in orbit around the Earth, studying the Earth's ozone layer, air quality and climate.

CloudSat is a NASA Earth observation satellite, which was launched on a Delta II rocket on April 28, 2006.

The common phrase "Red sun at morning" is a line from an ancient rhyme often repeated by mariners: Red sun at night, sailors' delight.

A supercell is a thunderstorm that is characterized by the presence of a mesocyclone: a deep, persistently rotating updraft.

Atmospheric optics deals with how the unique optical properties of the Earth's atmosphere cause a wide range of spectacular optical phenomena.

Twilight is the illumination of the Earth's lower atmosphere when the Sun itself is not directly visible because it is below the horizon.

Aqua (EOS PM-1) is a multi-national NASA scientific research satellite in orbit around the Earth, studying the precipitation, evaporation, and cycling of water.

The planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL), is the lowest part of the atmosphere, extending from the ground to the bottom of where cumulus clouds form.

Dew point is the highest temperature at which airborne water vapor will condense to form liquid dew.

The Saffir–Simpson hurricane wind scale (SSHWS), formerly the Saffir–Simpson hurricane scale (SSHS), classifies hurricanes – Western Hemisphere tropical cyclones that exceed the intensities of tropical depressions, and tropical storms – into five categories distinguished by the intensities of their sustained winds.

A low-pressure area, low or depression, is a region where the atmospheric pressure is lower than that of surrounding locations.

The Lockheed WP-3D Orion is a highly modified P-3 Orion used by the Aircraft Operations Center division of the National Oceanic and Atmospheric Administration (NOAA).

Frost is the coating or deposit of ice that may form in humid air in cold conditions, usually overnight.

The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal (30- to 90-day) variability in the tropical atmosphere.

In meteorology, an air mass is a volume of air defined by its temperature and water vapor content.

Jet streams are fast flowing, narrow, meandering air currents found in the atmosphere of some planets, including Earth.

A cold front is defined as the leading edge of a cooler mass of air, replacing at ground level a warmer mass of air, which lies within a fairly sharp surface trough of low pressure.

CALIPSO is a joint NASA (USA) and CNES (France) environmental satellite, built in the Cannes Mandelieu Space Center, which was launched atop a Delta II rocket on April 28, 2006.

A storm is any disturbed state of an environment or astronomical body's atmosphere especially affecting its surface, and strongly implying severe weather.

The Azores High (Portuguese: Anticiclone dos Açores) (also known as North Atlantic (Subtropical) High/Anticyclone or the Bermuda-Azores High, is a large subtropical semi-permanent centre of high atmospheric pressure typically found south of the Azores in the Atlantic Ocean, at the Horse latitudes. It forms one pole of the North Atlantic oscillation, the other being the Icelandic Low. The system influences the weather and climatic patterns of vast areas of North Africa and southern Europe, and to a lesser extent, eastern North America. The aridity of the Sahara Desert and the summer drought of the Mediterranean Basin is due to the large-scale subsidence and sinking motion of air in the system. In its summer position (the Bermuda High), the high is centered near Bermuda, and creates a southw

A weather map displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings.

The Beaufort scale /ˈboʊfərt/ is an empirical measure that relates wind speed to observed conditions at sea or on land.

The following outline is provided as an overview of and topical guide to meteorology: Meteorology – interdisciplinary scientific study of the atmosphere which explains and forecasts weather events.
