Across
- 6. the area over which the air mass forms
- 9. short-term variations in atmospheric phenomena that interact and affect the environment and life on Earth
- 10. a narrow region between two air masses of different densities
- 11. measures humidity
- 12. results in fluids and objects moving in an apparent curved path rather than a straight line
- 15. is the change in pitch or frequency that occurs due to the relative motion of a wave, such as sound or light, as it comes toward or goes away from an observer
- 17. two circulation belts of wind located between latitudes 30 degrees N and 30 degrees S
- 18. is the long-term average of variations in weather for a particular area
- 19. an instrument used for gathering upper-atmospheric data
- 20. measures air pressure
- 21. is a large volume of air that has the same characteristics, such as humidity and temperature
Down
- 1. measures wind speed
- 2. is a record of weather data for a particular site at a particular time
- 3. wind zones between 60 degrees N latitude and the North Pole, and 60 degrees S latitude and the South Pole
- 4. wind systems on Earth located between latitudes 30 degrees N and 60 degrees N, and 30 degrees S and 60 degrees S
- 5. is based on a comparison of current weather patterns to similar weather patterns from the past
- 7. measures temperature using either the Fahrenheit or Celsius scale
- 8. lines of equal temperatures
- 13. lines of equal pressure
- 14. is a narrow band of fast wind
- 16. is created by applying physical principles and mathematics to atmospheric variables and then making a prediction about how the variables will change over time
