Meteorology
| Question | Answer |
|---|---|
| Atmosphere | The gaseous envelope surrounding the earth. |
| Troposphere | The lowest layer of the atmosphere. |
| Ionosphere | The region of the earth's atmosphere between the stratosphere and the exosphere. |
| Ozone Layer | The layer of the upper atmosphere where most atmospheric ozone is concentrated. |
| Chloroflourocarbon | Any of several volatile, inert, saturated compounds of carbon, fluorine, chlorine, and hydrogen. |
| Radiation | The process in which energy is emitted as particles or waves. |
| Conduction | The act of conducting. |
| Convection | The vertical transport of atmospheric properties, especially upward. |
| Hydrosphere | The water on or surrounding the surface of the globe, including the water of the oceans and the water in the atmosphere. |
| Condensation | The process by which atmospheric water vapor liquefies to form fog, clouds, or the like, or solidifies to form snow or hail. |
| Coriolis Effect | The apparent deflection of moving objects when the motion is described relative to a rotating reference frame. |
| Jet stream | Strong, generally westerly winds concentrated in a relatively narrow and shallow stream in the upper troposphere of the earth. |
| Sea Breeze | A thermally produced wind blowing from a cool ocean surface onto adjoining warm land. |
| Land Breeze | A coastal breeze blowing at night from land to sea, caused by the difference in the rate of cooling of their respective surfaces. |
| Humidity | Humid condition; moistness; dampness. |
| 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. |
| Precipitation | Falling products of condensation in the atmosphere, as rain, snow, or hail. |
| Weather Front | The area where two air masses with different temperatures and densities collide, but do not mix. |
| Weather Station Model | |
| Climate | The composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years. |
| El Nino | 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. |
| Global Warming | An increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. |
