Across
- 3. A balloon equipped with meteorological apparatus which is sent into the atmosphere to provide information about the weather.
- 5. The necessary items for a particular purpose.
- 9. An instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
- 10. An instrument for measuring the humidity of the air or a gas.
- 11. Clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance
- 12. A visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes ranging up to several miles above sea level.
- 13. A hygrometer, which is an instrument used to measure the amount of water vapor in the air, consisting of a wet-bulb and a dry-bulb thermometer, the difference in the two thermometer readings being used to determine atmospheric humidity.
- 16. Pellets of frozen rain which fall in showers from cumulonimbus clouds.
- 17. Of or at a low or relatively low temperature, especially when compared with the human body.
- 19. An instrument used for showing the direction of the wind.
- 21. Atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer.
- 23. Not moving or not intended to be moved.
- 25. An instrument for measuring and indicating temperature.
- 27. A cloud forming a continuous horizontal gray sheet, often with rain or snow.
- 28. Stop, close up, or obstruct (an opening, orifice, or passage).
Down
- 1. Rain, snow, sleet, or hail that falls to the ground.
- 2. An instrument for measuring the speed of the wind, or of any current of gas.
- 4. A cloud forming a low layer of clumped or broken gray masses.
- 6. A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics. Often there is turbulence at a front, which is the borderline where two different air masses come together. The turbulence can cause clouds and storms.
- 7. A cloud generally characterized by thin, wispy strands.
- 8. A cloud forming a thin, more or less uniform, semitranslucent layer at high altitude.
- 14. gauge A device for collecting and measuring the amount of rain which falls.
- 15. sock A light, flexible cylinder or cone mounted on a mast to show the direction and strength of the wind, especially at an airfield.
- 18. A form of precipitation consisting of ice pellets, often mixed with rain or snow.
- 20. A cloud forming a towering mass with a flat base at fairly low altitude and often a flat top, as in thunderstorms.
- 22. Of or at a fairly or comfortably high temperature.
- 24. Moisture condensed from the atmosphere that falls visibly in separate drops.
- 26. A type of cloud forming a thick uniform gray layer at low altitude, from which rain or snow often falls without any lightning or thunder.
