Across
- 3. - air mass tend to approach from N,NW, or W
- 5. - warm air mass is replacing a cold air mass
- 9. - two cold air masses converge on a warm air mass
- 10. - measures wind speed
- 13. - boundary between two different air masses
- 14. - A line connecting points of equal atmospheric pressure
- 15. - A large body of air that has relatively uniform temperature and humidity
Down
- 1. - unit of measurement of atmospheric pressure
- 2. - measures temperature
- 4. - measures atmospheric pressure
- 6. - cold air mass is replacing warm air mass
- 7. - carry instruments to high altitudes to measure pressure, temperature, humidity and wind speed
- 8. - The boundary between two air masses
- 11. - measures wind direction
- 12. - air mass tend to approach from S, SE, or E
