Across
- 4. an instrument that measures the amount o atmospheric pressure.
- 5. global air circulation patterns within the atmosphere held to Earth by gravity and warmed by heat radiates from Earth.
- 7. an air mass with less atmospheric pressure than the surrounding air masses; air moves toward the area of low pressure.
- 10. amount of water vapor or moisture content in the air
- 11. the border between an advancing cold air mass and a retreating warm air mass.
Down
- 1. a map or chart that shows the weather conditions at a specific point in time over a specific region.
- 2. the day-to-day stae of the atmosphere.
- 3. the boundary between an advancing warm air mass and a receding cooler air mass.
- 6. an air mass with greater atmospheric pressure than the surrounding air masses; air moves away from the center of the high pressure.
- 8. a body of air extending over a large area that develops and retains specific characteristics of pressure, temperature, and humidity.
- 9. the force exerted by the atmosphere on Earth´s surface by the weight of the air above the surface.
