The length of the arc of the horizon (in degrees) intercepted between a given point and a reference direction, usually north, and measured clockwise from the reference direction. Azimuth may be synonymous with bearing, a navigational term that can have different meanings. Any point in space can be located relative to an observing point by its azimuth angle, elevation angle, and range.
Industry:Weather
The angle or distance by which two targets at the same range must be separated in azimuth to be distinguished by a radar. Targets separated less than this distance appear as a single target on the display. See radar resolution.
Industry:Weather
A warm and violently squally southeast wind in the center of the Massif Central of France. In spring it causes rapid melting of the snow, and in autumn it brings heavy rain; both cause flooding of the rivers. See marin.
Industry:Weather
Turbulence that is symmetrically distributed about the direction of the mean flow, as in a pipe or wind tunnel.
Industry:Weather
In hydrodynamics and fluid mechanics, a flow in which the streamlines are symmetrically located around an axis. Every longitudinal plane through the axis would exhibit the same streamline pattern.
Industry:Weather
With reference to a deformation field, that axis along which dilatation (stretching) of a fluid element is most rapid; it is normal to the axis of contraction.
Industry:Weather
The line joining the points of minimum pressure at the surface and at upper levels.
Industry:Weather
With reference to a deformation field, that axis along which contraction (shrinking) of a fluid element is most rapid; it is normal to the axis of dilatation.
Industry:Weather
The line joining the points of maximum pressure at the surface and at upper levels.
