Meteorology

Eric Taylor Studystack

QuestionAnswer
Ozone a form of oxygen produced when an electric spark or ultraviolet light is passed through air or oxygen
Troposphere the lowest layer of the atmosphere
Stratosphere the region of the upper atmosphere extending upward from the tropopause to about 30 miles
Mesosphere the region between the stratosphere and the thermosphere
Thermosphere the region of the upper atmosphere in which temperature increases continuously with altitude. Highest reigon of the atmosphere
Conduction the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts
Convection the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
Radiation the process in which energy is emitted as particles or waves.
Reflection he return of light, heat, sound, etc., after striking a surface.
Scattering the process in which a wave or beam of particles is diffused or deflected by collisions with particles of the medium that it traverses.
Greenhouse Effect atmospheric heating phenomenon, caused by short-wave solar radiation being transmitted inward through the earth's atmosphere - longer-wavelength heat radiation transmitted less outward by atmospheric carbon dioxide, water vapor, methane, and other gases.
Albedo the ratio of the light reflected by a planet or satellite to that received by it.
Isotherms a line on a weather map or chart connecting points having equal temperature
Precipitation falling products of condensation in the atmosphere, as rain, snow, or hail.
Latent Heat heat absorbed or radiated during a change of phase at constant temperature and pressure.
Evaporation to change from a liquid or solid state into vapor
Condensation the process by which atmospheric water vapor liquefies to form fog, clouds, or the like, or solidifies to form snow or hail.
Sublimation a purification or refinement; ennoblement.
Humidity moistness; dampness.
Saturated soaked, impregnated, or imbued thoroughly; charged thoroughly or completely; brought to a state of saturation.
Dew Point the temperature to which air must be cooled, at a given pressure and water-vapor content, for it to reach saturation; the temperature at which dew begins to form.
Hydrometer/Psychrometer an instrument for determining the specific gravity of a liquid, commonly consisting of a graduated tube weighted to float upright in the liquid whose specific gravity is being measured.
Weather Front ?
Condensation Nuclei a particle upon which condensation of water vapor occurs to form water drops or ice crystals.
Cirrus a cloud of a class characterized by thin white filaments or narrow bands and a composition of ice crystals
Cumulus a cloud of a class characterized by dense individual elements in the form of puffs, mounds, or towers, with flat bases and tops that often resemble cauliflower
Stratus a cloud of a class characterized by a gray, horizontal layer with a uniform base
Supersaturated o increase the concentration of (a solution) beyond saturation
Air Pressure the force exerted by air, whether compressed or unconfined, on any surface in contact with it
Barometer any instrument that measures atmospheric pressure
Pressure Gradient the change in atmospheric pressure per unit of horizontal distance in the direction in which pressure changes most rapidly.
Coriolis Effect the deflection of a body in motion with respect to the earth, as seen on the earth, attributed to a fictitious force but is caused by rotation of the earth and appearing as a deflection right in the N Hemisphere & a deflection left in the S Hemisphere.
Jet Stream strong, generally westerly winds concentrated in a relatively narrow and shallow stream in the upper troposphere of the earth.
Cyclone a large-scale, atmospheric wind-and-pressure system characterized by low pressure at its center and by circular wind motion, counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere.
Anti-Cyclone a circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere, counterclockwise in the Southern Hemisphere.
Trade Winds any of the nearly constant easterly winds that dominate most of the tropics and subtropics throughout the world
Westerlies any semipermanent belt of westerly winds, especially those that prevail at latitudes lying between the tropical and polar regions of the earth.
Polar Easterlies a wind that blows from the east.
Anemometer any instrument for measuring the speed of wind.
El NiƱo a warm ocean current of variable intensity that develops after late December along the coast of Ecuador and Peru and sometimes causes catastrophic weather conditions.
Air Mass a body of air covering a relatively wide area, exhibiting approximately uniform properties through any horizontal section.
Stationary Front a front between warm and cold air masses that is moving very slowly or not at all.
Occluded Front a composite front formed when a cold front overtakes a warm front and forces it aloft
Storm Surge an abnormal rise in the level of the sea along a coast caused by the onshore winds of a severe cyclone.
