Industry:Weather
The Arabic name for a northeasterly wind that occurs in winter on the Iranian coast of the Persian Gulf, especially near the entrance to the gulf and also on the Makran coast. It is probably of the bora type, though less strong, representing the outflow of cold air from central Asia. The n'aschi is part of the Asiatic monsoon system.
Industry:Weather
Radiation over a range of wavelengths for which the Planck function does not change significantly, but for which the spectral absorption coefficient may be highly variable
Transmission functions for narrowband radiation, unlike the exponential function for monochromatic radiation (see Bouguer's law), require the application of band models or numerical techniques such as the correlated-k method. Spectral intervals for narrowband radiation have widths that are typically 100 cm<sup>−1</sup>.

In a porous medium, the simultaneous flow of at least two immiscible fluids. Compare miscible displacement.
Industry:Weather
A radio direction-finder with which atmospherics are received from a limited sector related to the position of the antenna. The antenna is usually rotated continuously and the bearings of the atmospherics recorded automatically. See sferics.

In France, a wind coming from Narbonne; a north wind in the Roussillon region of southern France resembling the tramontana. If associated with an influx of arctic air, it may be very stormy with heavy falls of rain or snow. It is especially violent in the region of Perpignan where it blows in a succession of squalls for several days. In Provence it is rarer and blows from the west. In lower Languedoc and the southern Cévennes, the narbonnais is an infrequent, mild, moist, moderate southwest wind in winter and early spring, sometimes bringing thunderstorms.

1. Satellite subpoint on the earth's surface that is centered directly below the satellite. This is also referred to as the point of zero nadir angle for a satellite in earth orbit. 2. The point on a given observer's celestial sphere diametrically opposite his zenith, that is, directly below the observer.
Industry:Weather
A term used when the whole or a large part of a cloud undergoes a change from one genus to another. The new cloud is then given the name of the appropriate genus, followed by the name of the genus of the mother-cloud with the addition of the suffix “mutatus” (e.g., stratus stratocumulomutatus). Compare genitus.
Industry:Weather
A swamp or bog occurring in depressions in poorly drained alluvial or glacial terrain in northern Canada or the United States. The depression usually accumulates a saturated, highly compressible mixture of mineral particles and decaying vegetal matter, topped by a hummocky surface of sphagnum moss, and incapable of supporting heavy loads or traffic. In the colder and wetter parts of Alaska, these accumulations spread widely over low-amplitude terrain and are not confined to depressions.
