Across
- 3. Generally forms in the tropics because it needs warm water to form.
- 7. measure of the weight of the atmosphere on a given area of the surface of the Earth
- 8. warm air moves in and replaces the cooler air
- 10. brings clouds and precipitation
- 13. conditions at a particular time & place - such as current temperature (short term)
- 14. less dense areas continually rise, and the more dense areas continually sink creating a cyclical currents
- 15. effect of the Earth’s rotation on the path of air and water
- 18. Determines the direction from which the wind is blowing
- 19. area where two air masses with different temperatures and pressures meet
- 20. used to detect rain, snow & other forms of precipitation
- 22. colder air moves in and replaces the warmer air
- 23. instrument that is sent into the atmosphere to provide information about the weather
- 25. amount of water vapor present in the air
Down
- 1. body of air that has about the same temperature and humidity throughout
- 2. brings clear skies and calm weather
- 4. Measures the amount of rain that has fallen over a specific time period
- 5. instrument for determining the pressure of the atmosphere
- 6. movement of water from one location to another; driven by wind, water density differences, and tides
- 9. instrument used to measure humidity (moisture) in the air
- 11. instrument used to measure wind speed
- 12. front that moves very slowly or not at all because neither air mass is replacing the other
- 16. Many layers of mixed gases are held to the Earth by gravity
- 17. narrow band of high speed wind high in the atmosphere
- 21. forms when a cold front catches up and overtakes a warm front
- 24. average weather conditions in a certain place or during certain season (long term)
