2. stream, narrow, high-altitude band of strong winds that generally flow from west to east, encircling the Earth
4. effect, circulating air deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere
6. an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude
8. model, symbolic graphical representation of weather observations at a specific location, often used on weather maps
9. the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
10. an instrument for measuring the humidity of the air or a gas
12. effect, the increase or decrease in the frequency of sound, light, or other waves as the source and observer move towards or away from each other
15. a line on a map connecting points having the same atmospheric pressure at a given time or on average over a given period

1. instrument used to measure the temperature of the surrounding air
3. a boundary between two different air masses, characterized by varying temperatures, humidity, and wind conditions
5. a line on a map connecting points having the same temperature at a given time or on average over a given period
7. an instrument for measuring the speed of the wind, or of any current of gas
11. winds, winds that reliably blow east to west just north and south of the equator
13. the weather conditions prevailing in an area in general or over a long period
14. mass, a body of air with horizontally uniform temperature, humidity, and pressure
