Question | Answer |
Meteorology | The sceintific study of all atmospheric elements which combine to make up weather. |
Weather | The state of the lower atmosphere at any particular time and place. |
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. |
Hurricane | An intense tropical storm in the Caribbean Sea, Atlantic Ocean, Gulf of Mexico or eastern north Pacific Ocean, having sustained winds of greater than 74 mph. |
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 |
