- 6. an instrument measuring atmospheric pressure, used especially in weather forecasting
- 7. As air moves along the ground it absorbs heat, loses density and moves up into the atmosphere. ... In this process the warm air is cooled; it gains density and falls towards the earth and the cell repeats the cycle
- 8. a device for collecting and measuring the amount of rain which falls
- 14. weather system associated with rising air moving inward, usually brings rainy weather
- 15. the amount of water vapor in the air
- 17. low-level clouds characterized by horizontal layering
- 18. the weather conditions in an area in general or over a long period of time
- 19. an instrument for measuring and indicating temperature
- 22. winds that blow consistently in a given direction over a particular region on Earth
- 23. an instrument for measuring the speed of the wind
- 24. clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance
Down
- 1. A .... forms when a warm air mass runs into a slower cold air mass. The warm air slides over the cold air.
- 2. an instrument for measuring the humidity of the air
- 3. measurement that indicates how hot or cold something is
- 4. when a cold air mass collides and slides under a warm air mass, the resulting ...... may produce thunderstorms
- 5. weather system associated with sinking air moving outward, usually brings fair weather
- 7. the process of water vapor turning back into liquid water and forming clouds
- 9. the force of air pressing down on an area
- 10. rain, snow, sleet, or hail that falls to the ground
- 11. instrument for showing the direction of the wind
- 12. a large body of air with generally uniform temperature and humidity
- 13. change of water from a liquid to a gas
- 16. the condition of the atmosphere in one area at a particular time
- 20. state of the atmosphere at a particular place during a short period of time
- 21. A balloon used to carry instruments aloft to gather meteorological data in the atmosphere
