knowledge engineering

Weather; Meteorology

The discipline that addresses the planning and programming tasks of building, testing, and deploying knowledge-based systems. It includes the development of expert systems, including knowledge ...

linear water wave theory

Weather; Meteorology

The development of wave equations from the full equations of motion, based on the assumption that the wave height to wavelength ratio (wave steepness) is small. From this theory it is possible to ...

lightning current

Weather; Meteorology

The current flowing in a component of the lightning flash. It is usually considered to be the current in the return stroke.

Lagrangian mean current

Weather; Meteorology

The current determined by dividing the displacement of a fluid particle by the time traveled.

Lagrangian correlation

Weather; Meteorology

The correlation between the properties of a flow following a single parcel of fluid through its space and time variations. Compare Eulerian correlation; see correlation coefficient.

kinematics
