| Question | Answer |
| Air mass | A larger body body of air in the troposphere with similar characteristics of pressure, moisture, and temperature |
| Air pressure gradient | the difference in air pressure for a specific distance |
| anemometer | device used to measure wind speed |
| Atmospheric (barometric) pressure | the pressure due to the weight of the overlying atmosphere pushing down on any given area |
| barometer | device used to measure air pressure |
| Cloud cover | The fraction of percent of the total sky at a location that is covered by clouds; usually expressed in tenths |
| Cold front | The boundary of an advancing cold air mass and a warmer air mass, where the underlying cold air pushes forward like a wedge; characterized by a steep |
| cyclone | a low pressure portion of the troposphere that has air moving towards its center, usually rotates counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere; includes hurricanes, tornadoes, and mid-latitudes, also called a low |
| Dew point | the temperature at which air is filled with water vapor |
| front | where two air masses of different characteristics meet, an interface, or boundary |
| humidity | a general term that refers to the water vapor content of the atmosphere |
| isobar | air pressure is often shown on weather maps by the use of isolines |
| Jet stream | bands of easterly moving air at the top of the troposphere |
| monsoon | regular and extreme weather changes caused by the shifting wind and pressure belts |
| Occluded front | the boundary of opposing wedges of cold air masses formed when a cold front overtakes a warm front, lifting the warm air mass off the ground |
| Planetary wind belt | East-West zones on Earth where the wind blows from one direction much of the time |
| Polar front | an ever changing boundary in the middle latitudes between the colder air masses toward the poles and the warmer air masses toward the equator |
| precipitation | falling liquid or solid of water from clouds toward Earth’s surface |
| probability | chance or likelihood of something happening. |
| psychrometer | an instrument that is used to indirectly measure the amount of water vapor in the air, such as a sling psychrometer |
| radar | stands for RAdio Detection And Ranging instrument-reflects radio electromagnetic energy off the aerosols of precipitation and clouds |
| Relative humidity | the ratio of the amount of water vapor in the air to the maximum amount it can hold |
| Stationary front | a weather condition in which the boundary between two air masses remains in the same position |
| Station model | indicates a site’s weather variables for a specific time of day |
| troposphere | the part of the atmosphere imediately above the Earth’s surface; where most weather changes occur |
| visibility | the furthest distanceat which one can see a pominant object at Earth’s surface with the naked eye. |
| Warm front | the boundary of an advancing warm air mass and a retreating wedge of a cooler air mass |
| Water vapor | gaseous water in the atmosphere |
| Weather variables | condition of the atmosphere such as temperature, air pressure, wind, moisture, cloud cover, precipitation, and storms |
| Tornado | a rapidly rotating, extremely low-pressure funnel that hangs down from thunderstorm clouds towards earth’s surface |
| Thunder storm | heavy rainstorm accompanied by thunder and lightning from thunderstorm type clouds |
| blizzard | a storm with winds of 35 miles an hour or greater associated with considerable amounts of falling and/or blowing snow |
