| Question | Answer |
|---|---|
| The long term average of weather in a particular place that is usually stable and changes slowly. | Climate |
| Description of what the atmosphere is like at a particular time and place. | Weather |
| A large body of air that has the same conditions throughout. | Air Mass |
| The Type of front that occurs when advancing warm air displaces cold air along a gradual slope; represented by evenly spaced red half circles on a weather map. | Warm Front |
| The type of front that occurs when cold dense air forces less dense warm air upward along a steep slope; represented by blue triangles pointing the direction the front is moving on a weather map. | Cold Front |
| The front that occurs when two air masses that have similar temperatures and pressures meet and neither advances; shown by a line with alternating red half circles and blue triangles facing in opposite directions on a weather map. | Stationary Front |
| The type of front that occurs when a cold front overtakes a warm front and forces it upward causing the advancing cold air to collide with another cold air mass; shown on a weather map by alternating, evenly spaced, purple half circles and triangles. | Occluded Front |
| Air from aloft sinks and moves away from the center when it reaches the surface of the Earth; usually associated with fair weather;represented by a blue “H” on a weather map. | High Pressure System |
| Air from the surface rises, cools, and condenses into clouds and precipitation rotates in a counterclockwise direction in the northern hemisphere; usually associated with cloudy weather and precipitation; represented by a red “L” on a weather map. | Low Pressure System |
| Describes a moist airmass that originates over a body of water. | Maritime Airmass |
| Describes a dry airmass that originates over land. | Continental Airmass |
| Warm airmass that originates over the warm waters of the tropics and Pacific Ocean south of California. | Tropical Airmass |
| Cold airmass that originates over Canada. | Polar Airmass |
| Extremely cold and dry air masses that are created over land at very high latitudes. | Arctic Airmass |
