level of free convection (LFC)

Weather; Meteorology

The level at which a parcel of air lifted dry-adiabatically until saturated and saturation-adiabatically thereafter would first become warmer than its surroundings in a ...

line echo wave pattern (LEWP)

Weather; Meteorology

A special configuration in a line of convective storms that indicates the presence of a low pressure area and the possibility of damaging winds and tornadoes. In response to very ...

linear depolarization ratio (LDR)

Weather; Meteorology

The ratio of the power received in the orthogonal, or cross-polarized, channel to that received in the transmission, or copolarized, channel of a dual- channel radar, when a ...

lifting condensation level (LCL)

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 ...

kilogram calorie

Weather; Meteorology

A unit of heat equal to 1000 small calories.

lifting condensation level (LCL) zone

Weather; Meteorology

The range of altitudes within which the lifting condensation level (LCL) occurs for different air parcels rising from near the surface. Due to natural variability and land-use ...

local area coverage (LAC)

Weather; Meteorology

Ten minutes of AVHRR data at full resolution (1. 1 km at nadir) stored on digital tape recorders for subsequent playback to NOAA Command and Data Acquisition ground stations.
