Drizzle that falls in liquid form but freezes upon impact to form a coating of glaze. In U. S. Aviation weather observations, this hydrometeor is encoded ZL. The physical cause of this phenomenon is the same as that for freezing rain.
Industry:Weather
Distribution of the geopotential altitude of an isobaric surface.
Industry:Weather
Distribution of the troughs and ridges as depicted on upper-air charts.
Industry:Weather
Depth into soil that frost has penetrated at any given time. See frost line.
Industry:Weather
Desalinated seawater frozen to the base of some Antarctic ice shelves that becomes exposed to view when an iceberg separates from the shelf and capsizes. The green color of the ice, and of the seawater from which it froze, is due to dissolved organic matter.
Industry:Weather
Descriptive of air that is stimulating and refreshing. See fresh breeze, fresh gale.
Industry:Weather
Datasets designed to provide a complete historical record of the climate. Such datasets include parameters such as surface air temperatures, sea surface temperatures, tropospheric and stratospheric temperatures, atmospheric water vapor, and radiative fluxes at the top of the atmosphere. For maximum value, such datasets should be designed to minimize the inhomogeneities associated with changes in instrumentation, instrument exposure, or observing techniques.
Industry:Weather
Dark absorption lines in the solar spectrum seen against the bright continuum spectrum of the photosphere. Associated with specific atomic energy level transitions, these absorption features occur as a consequence of wavelength variations in the atomic opacity and the outward decrease in photospheric temperature (after the German physicist Joseph Fraunhofer, 1787–1826).
Industry:Weather
Dark, sinuous ribbon observed on the solar disk. Filaments consist of higher density, and lower temperature material supported by solar magnetic fields that absorb the relatively intense disk emission (for example, as seen in Hα emission of neutral hydrogen). As these features rotate across the sun's limb they appear as quiescent prominences and are seen in elevation above the edge of the sun.
