longwave radiation"In meteorology, a term used loosely to distinguish radiation at wavelengths longer than about 4 μm, usually of terrestrial origin, from those at shorter wavelengths (shortwave radiation), usually of solar origin.
Longwave Radiation - in meteorology, radiation having a wavelength greater than that of visible light
Low - in meteorology, an region of low pressure; see also cyclone ...
Longwave radiation: Radiant energy characterized by wavelengths primarily between 4 and 100 *m with a maximum near 10 *m. Also known as Terrestial radiation.
Mesocyclone: A vertical column of rotating air within a severe thunderstorm.
Longwave Radiation
A term used to describe the infrared energy emitted by the earth and atmosphere at wavelengths between about 5 and 25 micrometers. Compare shortwave radiation.
Longwave Trough ...

Mesosphere The upper region of the homosphere from 50 to 80 km (30 to 50 mi) above the ground; designated by temperature criteria; has very low pressures.
Longwave radiation A term most often used to describe the infrared energy emitted by the earth and the atmosphere.

Longwave radiation(1)
The radiation emitted in the spectral wavelength greater than 4 micrometers corresponding to the radiation emitted from the Earth and atmosphere.
This outgoing longwave radiation is partially trapped by greenhouse gases such as carbon dioxide, methane and water vapour which then radiate the energy in all directions, warming the earth's surface and atmosphere.
Abbreviated IR; also called "longwave radiation". insolation The solar radiation incident on a unit horizontal surface at the top of the atmosphere. It is sometimes referred to as solar irradiance.
OLR - Outgoing Longwave Radiation is a polar satellite derived measurement of the radiative character of energy radiated from the warmer earth surface to cooler space.
See shortwave radiation and longwave radiation.Radiation FogA fog that forms when outgoing longwave radiation cools the near-surface air below its dew point temperature.
Greenhouse effectThe warming of the atmosphere by the trapping of longwave radiation (heat) being radiated to space. The gases most responsible for this effect are water vapor and carbon dioxide.
Outgoing Longwave RadiationOutgoing Longwave Radiation is a polar satellite derived measurement of the radiative character of energy radiated from the warmer earth surface to cooler space.
These focus areas are shortwave radiation, longwave radiation, clouds, aerosols, atmospheric state, and surface energy exchange. These areas will change over time as research goals are narrowed and new observational programs are developed.
In 2000, a comparison between measurements and dozens of CGM simulations of ENSO-driven tropical precipitation, water vapor, temperature, and outgoing longwave radiation found similarity between measurements and simulation of most factors.

Because most tropical rainfall is convective, and convective cloud tops are very cold (emitting little longwave radiation), the MJO is most obvious in the variation of outgoing longwave radiation (OLR), ...
Terrestrial radiation Longwave radiation emitted by the Earth, including its atmosphere.
Atmospheric heating caused by solar radiation being readily transmitted inward through the earth's atmosphere but longwave radiation less readily transmitted outward, due to absorption by certain gases in the atmosphere.
Greenhouse Gases ...
RADIATIONAL COOLING- The earth's surface cooling by emitting longwave radiation. The best radiational cooling occurs on clear nights.
