Across
- 3. measures relative humidity
- 6. a natural movement of air, sometimes with considerable force, from an area of high density and pressure to an area of low density and pressure
- 7. the flow of air in circular patterns; air rises, flows parallel to Earth's surface, falls, flows parallel to Earth's surface, and rises again
- 10. measures air temperature
- 12. a large tropical weather system consisting of an extremely low-pressure air mass with heavy rains and wind speeds of at least 119 km/h
- 16. measures wind speed
- 17. a form of energy that spreads out as it travels
- 19. air in convection currents moves parallel to Earth's surface as warm air slides under cooler air
- 20. warm air is less dense, it flows over the cold air at a warm front
- 21. warmer temperature, lower air pressure
- 23. produce other weather events
Down
- 1. measures wind direction
- 2. directional movements of ocean water; surface currents result from steady winds over the ocean surface; deep currents result from density variations due to temperature and salinity differences
- 4. wind created by sinking cool air
- 5. an air mass with greater atmospheric pressure than the surrounding air masses; air moves away from the center of the high pressure, traveling in a clockwise direction in the northern hemisphere and a counterclockwise direction in the southern hemisphere
- 8. cool air is denser, it flows beneath the warm air at a cold front
- 9. a large tropical weather system consisting of an extremely low-pressure air mass with heavy rains and wind speeds of at least 119 km/h
- 11. cooler temperatures, higher air pressure
- 13. weather at such a front tends not to change for as long as the front stays in place
- 14. amount of water vapor or moisture content in the air
- 15. measures air pressure
- 18. wind created by rising warm air
- 22. the day to day state of the atmosphere
- 24. refers to the transfer of heat through liquid or gas, such as air
