Across
  1. 2. line on a weather map connecting areas of equal pressure
  2. 8. weather instrument used to measure wind speed.
  3. 9. short-term variations in atmosphere phenomena that interact and affect the environment and life on Earth.
  4. 12. forecast weather forecast that compares current weather patterns to patterns that occurred in the past.
  5. 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.
  6. 16. narrow wind band that occurs above large temperature contrasts and can flow as fast as 185 km/h.
  7. 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.
  8. 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.
  9. 20. balloon-borne weather instrument whose sensors measure air pressure, humidity, temperature, wind speed, and wind direction of the upper atmosphere.
  10. 21. instrument used to measure temperature using either the Faherenheit or Celsius scale.
Down
  1. 1. model record of weather data for a specific place at a specific time, using meteorological symbols.
  2. 3. area over which an air mass forms.
  3. 4. large volume of air that has the characteristics of the area over which it forms.
  4. 5. the long-term average of variation in weather for a particular area.
  5. 6. global wind systems that lie between latitudes 60° N and 60° S and the poles and is characterized by cold air.
  6. 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.
  7. 10. weather instrument used to measure humidity.
  8. 11. forecast weather forecast that uses numerical data to predict how atmospheric variables change over time.
  9. 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.
  10. 14. instrument used to measure air pressure.
