local thermodynamic equilibrium (LTE)

Weather; Meteorology

A condition under which matter emits radiation based on its intrinsic properties and its temperature, uninfluenced by the magnitude of any incident radiation. LTE occurs when the ...

low-level jet (LLJ)

Weather; Meteorology

A jet stream that is typically found in the lower 2–3 km of the troposphere. At night, sometimes called a nocturnal jet. Examples are the African jet and the Somali jet.

isentropic condensation level

Weather; Meteorology

The level at which a parcel of moist air lifted dry-adiabatically would become saturated. On a thermodynamic diagram it is located at the point of intersection of the dry adiabat ...

lightning imaging sensor (LIS)

Weather; Meteorology

An instrument designed to detect lightning from space as part of TRMM.

laser-induced fluorescence (LIF)

Weather; Meteorology

Experimental technique in which the absorption of laser radiation excites a molecule or atom to an excited energy level, followed by emission of radiation as the system relaxes. ...

level of free sink (LFS)

Weather; Meteorology

The level at which a parcel of descending air becomes cooler than its surroundings. On a thermodynamic diagram the level of free sink is given by the point of intersection of the ...

limited fine-mesh model (LFM)

Weather; Meteorology

An adaptation of Shuman and Hovermale's (1968) hemispheric six-layer primitive equations numerical weather prediction model. It used a finer horizontal grid mesh (190. 5 km) to ...
