Meteorology

An interfacial region in which flow is smooth and nonturbulent. Above a surface, a laminar layer will develop and fluid velocity will increase with distance from the surface, but not indefinitely. At ...

Lightning detection network

Weather; Meteorology

An integrated array of lightning direction finders that provide information for trigonometric location of cloud-to-ground lightning discharges. Timing and direction information from individual ...

Linear instability

Weather; Meteorology

An instability that can be described (to first-order accuracy) by linear (or tangent linear) equations.

Love wave

Weather; Meteorology

A type of seismic surface wave having a horizontal motion that is shear or transverse to the direction of propagation. Its velocity depends only on density and rigidity modulus, and not on bulk ...

K–ε closure

Weather; Meteorology

A type of one-and-a-half-order turbulence closure that retains forecast equations for mean (first-order statistics) variables such as potential temperature and wind components, and also retains ...

Lysimeter

Weather; Meteorology

A type of evaporation gauge that consists of a tank or pan of soil placed in a field and manipulated so that the soil, water, thermal, and vegetative properties in the tank duplicate as closely as ...

Lambert conic projection

Weather; Meteorology

A type of conformal map in which features on a sphere are projected onto a cone. The cone can either be tangent to the sphere, for which contact is along one circle, or pass through the sphere, for ...
