|---|---|
| Meteorology | The sceintific study of all atmospheric elements which combine to make up weather. |

| Atmosphere | A 600 mile thick blanket of gases surrounding the earth. |
| Troposphere | The lowest layer of the earth's atmosphere where all weather occurs. |
| Jet Stream | A strong, high-level wind that can reach speeds in excess of 200 mph circling the earth in the upper troposphere. |
| Air Mass | An extensive body of air having the same temperature and moisture characteristics. |
| Cumulonimbus | A vertically developed thunderstorm cloud, often with an anvilshaped top and accompanied by heavy showers, lightning, thunder, hail, or strong, gusty winds. |
| Wind Chill Index | The calculation of temperature that factors in the effects of wind and temperature on the human body to better describe what the temperature feels like. |

| Eye (of Hurricane) | The center of a hurricane, characterized by a roughly circular area of light winds. |
| Isobar | Denotes lines of equal pressure on a weather map |
| Front | Collision between a cold dry air mass and a warm moist air mass |
| Troposphere | Area of atmosphere where weather occurs |
| Stratus | Gray skies - type of cloud |
| Climate | Long duration over a large land area |
| Anemometer/Beaufort Scale | Both are used to assess wind forces |
| anticyclone | high pressure system |
| Temperature | Most instrumental in changing the weather in different parts of the atmosphere. |
| Aneroid Barometer | measures atmospheric pressure |
