Company Profile:
The American Meteorological Society promotes the development and dissemination of information and education on the atmospheric and related oceanic and hydrologic sciences and the advancement of their professional applications. Founded in 1919, AMS has a membership of more than 14,000 professionals, ...
Any of the individual, elemental particles that comprise an atom. The ones most commonly encountered in atmospheric sciences are the proton, neutron, and electron. Other, less common particles such as neutrinos may also penetrate the atmosphere as constituents of the solar wind.
Industry:Weather
Any of several types of ice crystal found in snow. A snow crystal is a single crystal, in contrast to a snowflake, which is usually an aggregate of many single snow crystals.
Industry:Weather
Any of a series of relatively long-lived compounds that sequester more reactive oxides of nitrogen, hydrogen, and halogen in the stratosphere. Examples include 1) chlorine nitrate, ClNO<sub>3</sub>, which ties up both ClO and NO<sub>2</sub>, and 2) HO<sub>2</sub>NO<sub>2</sub>, which is a HO<sub>2</sub> and NO<sub>2</sub> reservoir. The presence of these compounds serves to mediate the ability of the more reactive oxides to destroy stratospheric ozone, or to produce tropospheric ozone.
Industry:Weather
Any net electrical charge that exists in a given region of space. In electronics, this usually refers to the electrons in the space between the filament and plate of an electron tube. In atmospheric electricity, space charge refers to a preponderance of either negative or positive ions within any given portion of the atmosphere. A net positive space charge is found in fair weather at all altitudes in the atmosphere and is largest near the earth's surface. The general downward flux of this positive space charge is known as the air–earth conduction current.
Industry:Weather
Any model specifying a space distribution of some meteorological elements. The distribution of clouds, precipitation, wind, temperature, and pressure in the vicinity of a front is an example of a synoptic model.
Industry:Weather
Any instrument used to cause reflected radiation to return along paths parallel to those of their corresponding incident rays. One type, the corner reflector, is an efficient radar target. Trihedral prisms are used to retroreflect light in measuring atmospheric extinction coefficients.
Industry:Weather
Any instrument designed to measure rain amount; includes recording, nonrecording, and rain-intensity gauges.
Industry:Weather
Any function of time ''f''(''t'') is periodic with period ''t'' if ''f''(''t'') &#61; ''f''(''t'' + τ) for all times ''t'', where τ is the smallest number for which this equality holds. Without qualification, period often means temporal period, but could mean spatial period (wavelength), the repeat distance of a spatially periodic function. See frequency.
Industry:Weather
Any hot desert wind other than the simoom.
Industry:Weather
Any form of weather modification, usually involving cloud seeding, where the objective is to induce the formation of precipitation or to enhance the amount.
