Across
- 2. systems have more air pressure than their surroundings
- 4. This is the percent of water vapor in the air relative to the total amount the air can hold
- 7. Systems that have less pressure are called
- 11. clouds that form high in the troposphere
- 12. is the science dealing with the atmosphere
- 13. water vapor condenses as ice crystals but they melt in warmer air in the atmosphere and then refreeze closer to the ground as small ice pellets
- 14. is the state of the atmosphere
- 15. shows the continuous movement of water within the Earth and atmosphere
- 17. The temperature at which water vapor condenses is called the
- 18. is used to measure humidity.
- 20. forms in thunderstorms when strong updrafts carry rain high into the troposphere
- 21. measures the amount of rainfall over a specified period of time.
- 22. a weather radar is used to locate precipitation
Down
- 1. This instrument is used to measure wind speed.
- 3. This is used to measure temperature
- 5. is a large body of air that has about the same conditions throughout
- 6. clouds that occur low in the troposphere
- 8. is all weather conditions for a particular location averaged over a long period of time.
- 9. measures the amount of air pressure in the air
- 10. is the amount of water vapor in the air.
- 13. water vapor condenses as ice crystals and the temperature remains below freezing as it falls to the ground
- 14. contains many instruments
- 16. water droplets that fall when the temperature is above freezing
- 19. clouds that are white and puffy form in the troposphere
