| TERM/PHRASE | CLASSIFICATION | DESCRIPTION |
|---|---|---|
| Absolute Humidity | is a weather element | which indicates the actual amount of water vapor in a unit volume of air |
| Adiabatic Changes | is a general term | which indicates changes in temperature with no heat energy being added or lost |
| Air Mass | is a large body of air | which has the same condition of moisture and temperature throughout its horizontal levels |
| Anemometer | is a weather instrument | which measures the speed of wind |
| Anticyclone | is a mass of circulating air | which moves outward from a high-pressure area |
| Cold Front | is a air mass movement | in which a mass of cold air advances into territory occupied by warm air |
| Condensation | is cooled water vapor | which changes from an invisible gas to liquid water; what forms clouds |
| Cyclone | is a mass of circulating air | which blows in toward a low-pressure area |
| Dew Point | is a temperature level | which indicates the temperature of the air at which condensation takes place |
| Front | is a weather term for | the leading edge of an air mass |
| Frontal Precipitation | is a type of precipitation | that occurs when a warm moist body of air is forced to rise by a cooler body of air. |
| Hurricane | is a type of weather | in which a large mass of air whirls at extremely high velocity around a low-pressure area originating in ocean areas |
| Isobar | is a type of isoline | which is used on a weather map to connect areas of equal atmospheric pressure |
| Jet Stream | is a weather term | which refers to a changing, narrow, high-velocity core of air movement located in the lower stratosphere, and related to the position of the polar front and mid-latitude cyclones |
| Meteorologist | is a person | who studies and forecasts the weather |
| Occluded Front | is a frontal boundary | which is formed in such a way as to lift the warm air from the surface of the earth |
| Relative Humidity | is a weather element | which indicates the ratio between absolute humidity and humidity capacity at a given temperature , usually expressed as a percentage |
| Stationary Front | is a front boundary | along which there is little movement |
| Temperature Inversion | is a temperature condition | in which a mass of cold air is trapped beneath a mass of warm air |
| Tornado | is a type of cyclone | which is violent, rotating, land-based and capable of causing great destruction |
| Urban Heat island | is a build up of heat | which is created in an urban environment resulting from buildings and energy consumption |
| Warm Front | is air mass movement | in which a mass of warm air advances into a territory covered by cold air |
| Weather | is the general term for | the short-term, day to day, or hour to hour, temperature and precipitation, clouds, humidity, wind, and sunshine conditions |
| Wind Arrow | is a weather map symbol | which points in the direction from which the wind is comings |
| Wind-Chill Factor | is a comfort index | which combines the effect of temperature and wind to tell you how the weather feels |
| Wind Tunneling | is an accleration of wind | which is caused by channelling between buildings |
