level of nondivergence
Weather; Meteorology
A level in the atmosphere throughout which the horizontal velocity divergence is zero. Although in some meteorological situations there may be several such surfaces (not ...
layer of no motion
Weather; Meteorology
A layer, assumed to be at rest, at some depth in the ocean. This implies that the isobaric surfaces within the layer are level, and hence they may be used as reference surfaces ...
laminar sublayer
Weather; Meteorology
A layer in which the fluid undergoes smooth, nonturbulent flow. It is found between any surface and a turbulent layer above. See laminar boundary layer, laminar flow.
Lambert's law
Weather; Meteorology
A law governing the angular dependence of emitted or reflected radiation from an idealized surface. The radiation emitted from or reflected by a surface obeying Lambert's law is ...
Krypton hygrometer
Weather; Meteorology
A hygrometer technically very similar to the Lyman-alpha hygrometer, but with the hydrogen radiation source replaced by a Krypton glow tube. The main emission is at 123. 58 nm, ...
Lyman-alpha hygrometer
Weather; Meteorology
A hygrometer based on the absorption of radiation by water vapor at the Lyman-alpha line, which is an emission line of atomic hydrogen at 121. 567 nm. Lyman-alpha radiation can be ...
Johnson–Williams liquid water probe
Weather; Meteorology
A hot-wire type instrument for measuring the liquid water content of clouds in situ. The probe is most often used on research aircraft, but also occasionally at mountain-top ...
