Module 9 Meteorology

4. 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
5. short-term variations in atmosphere phenomena that interact and affect the environment and life on Earth
7. line on a weather map connecting areas of equal pressure
11. area over which an air mass forms
13. global wind systems that lie between latitudes 60°N and 60°S and the poles and is characterized by cold air
15. balloon-borne weather instrument whose sensors measure air pressure, humidity, temperature, wind speed, and wind direction of the upper atmosphere
16. narrow wind band that occurs above large temperature contrasts and can flow as fast as 185 km/h
17. line on a weather map connecting areas of equal temperature
19. large volume of air that has the characteristics of the area over which it forms
20. weather forced that uses numerical data to predict how atmospheric variables change over time

1. 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
2. global wind system that lies between 30° and 60° north and south latitude, where surface air moves toward the poles in an easterly direction
3. weather forecast that compares current weather patterns to patterns that occurred in the past
6. effect of a rotating body that influences the motion of any object or fluid
8. change in the wave frequency that occurs due to the relative motion of the wave as it moves toward or away from an observer
9. weather instrument used to measure humidity
10. instrument used to measure temperature using either the Fahrenheit or Celsius scale
11. record of weather data for a specific place at a specific time, using meteorological symbols
12. weather instrument used to measure wind speed
14. the long-term averages and variations in weather for a particular area
18. instrument used to measure air pressure
