A diagram in which the speed of the zonal flow is one coordinate and latitude is the other.
Industry:Weather
The wind, or wind component, along the local parallel of latitude, as distinguished from the meridional wind.
In a horizontal coordinate system fixed locally with the ''x'' axis directed eastward and the ''y'' axis directed northward, the zonal wind is positive if it blows from the west and negative if from the east. 2. Same as westerlies.
Industry:Weather
That portion of the lithosphere in which the pore spaces in rock, soil material, and soil are partially or temporarily filled with air, that is, the region above the water table and its accompanying capillary fringe.
Industry:Weather
A faint cone of light in the night sky extending upward from the horizon in the direction of the ecliptic (zodiac).
It is seen at tropical latitudes for a few hours after sunset or before sunrise. It is mainly explained by the forward scattering of sunlight by particles in interplanetary space along the ecliptic.
Industry:Weather
The kinetic energy of the mean zonal wind, obtained by averaging the component of the wind along a fixed latitude circle.
Industry:Weather
A region surrounding or at some distance from a sound source, such as an explosion, in which sound cannot be detected, usually by a human without special aids, even though the source may be in visual range.

Un arcobaleno formata quando la sorgente luminosa è la luna, piuttosto che il sole. Anche se l'ottica di entrambi è la stessa, la luminanza dell'arcobaleno lunare è molto più bassa. A causa della ridotta sensibilità al colore a bassi livelli di luce dell'occhio dell'arco possa esibire poco colore. Ci sono diverse ragioni perché l'arcobaleno lunare è visto molto meno frequentemente che l'arco solare. Mentre la luna e il sole spendere tempo uguale sopra l'orizzonte, quando sono entrambi presenti, può essere visto solo un arco solare. Questo, di per sé, significa che l'arcobaleno lunare potrebbe formare solo la metà come spesso. Ulteriormente, la Luna passa attraverso fasi e quindi anche di notte non possa contribuire abbastanza luce per produrre un arco discernibile. Infine, le docce convettive in cui viene vista frequentemente arcobaleno sono molto meno comuni di notte.
