Across
- 2. line on a weather map connecting areas of equal pressure
- 8. weather instrument used to measure wind speed.
- 9. short-term variations in atmosphere phenomena that interact and affect the environment and life on Earth.
- 12. forecast weather forecast that compares current weather patterns to patterns that occurred in the past.
- 15. two global wind systems that flow between 30° north and south latitudes, where air sinks, warms, and returns to the equator in a westerly direction.
- 16. narrow wind band that occurs above large temperature contrasts and can flow as fast as 185 km/h.
- 17. change in the wave frequency that occurs due to the relative motion of the wave as it moves toward or away from an observer.
- 18. global wind system that lies between 30° and 60° north and south latitudes, where surface air moves toward the poles in an easterly direction.
- 20. balloon-borne weather instrument whose sensors measure air pressure, humidity, temperature, wind speed, and wind direction of the upper atmosphere.
- 21. instrument used to measure temperature using either the Faherenheit or Celsius scale.
Down
- 1. model record of weather data for a specific place at a specific time, using meteorological symbols.
- 3. area over which an air mass forms.
- 4. large volume of air that has the characteristics of the area over which it forms.
- 5. the long-term average of variation in weather for a particular area.
- 6. global wind systems that lie between latitudes 60° N and 60° S and the poles and is characterized by cold air.
- 7. boundary between two air masses of differing densities; can be cold, warm, stationary, or occluded and can stretch over large areas of Earth’s surface.
- 10. weather instrument used to measure humidity.
- 11. forecast weather forecast that uses numerical data to predict how atmospheric variables change over time.
- 13. effect of a rotating body that influences the motion of any object or fluid; on Earth, air moving north or south from the equator appears to move right or left, respectively; the combination of the Coriolis effect and Earth’s heat imbalance creates the trade winds, polar easterlies, and prevailing westerlies.
- 14. instrument used to measure air pressure.
- 19. line on a weather map connecting areas of equal temperature.
