Across
- 3. a unit for measuring temperature

- 7. a system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) or clockwise (southern hemisphere) circulation; a depression
- 13. a term used to describe a change in atmospheric conditions or weather patterns
- 15. the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms
- 16. tiny drops of water that form on cool surfaces at night, when atmospheric vapor condenses
- 17. the perceptible natural movement of the air
- 19. the blanket of gas on the surface of a planet
- 20. an arch of colors formed in the sky in certain circumstances, caused by the refraction and dispersion of the sun’s light by rain or other water droplets in the atmosphere
- 22. a cloud with its base at the earth's surface
- 25. the transition zone between two distinct air masses
- 26. part of the weather cycle; rain, snow, sleet, or hail that falls to the ground
- 27. of or denoting a scale of temperature in which water freezes at 0 degrees and boils at 100 degrees under standard conditions
- 28. a brief, strong rush of wind
- 29. of or at a low or relatively low temperature, especially when compared with the human body
- 31. the process by which a liquid changes into a gas
- 32. downward moving air, usually within a thunderstorm cell
- 35. small drops between 0.2 and 0.5 mm in diameter that fall slowly and reduce visibility more than light rain
- 36. pellets of frozen rain that fall in showers from cumulonimbus clouds
- 37. a heavy rainfall
- 38. a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air
Down
- 1. a body of water or air moving in a definite direction, especially through a surrounding body of water or air in which there is less movement
- 2. an instrument that measures atmospheric pressure
- 5. the invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogen
- 6. to predict (weather conditions) on the basis of correlated meteorological observations
- 7. a visible mass of condensed water vapor floating in the atmosphere, typically high above the ground
- 8. the accumulation of daily and seasonal weather events over a long period of time. A description of aggregate weather conditions; the sum of all statistical weather information that helps describe a place or region.
- 9. atmospheric moisture
- 10. the occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud
- 11. of or denoting a scale of temperature on which water freezes at 32 degrees and boils at 212 degrees under standard conditions
- 12. the degree or intensity of heat present in a substance or object
- 14. the last stage of the water cycle; also called. storage; the water that falls from the sky is stored. in rivers, lakes and oceans.
- 18. to be carried slowly by a current of air or water
- 21. a severe weather condition characterized by low temperatures and strong winds (greater than 32 mi/hr) bearing a great amount of snow
- 23. part of the weather cycle; the conversion of a vapor or gas to a liquid
- 24. an instrument containing a magnetized pointer that shows the direction of magnetic north and bearings from it
- 30. a process that occurs in subfreezing air when water vapor changes directly to ice without becoming a liquid first
- 33. a covering of ice produced by deposition (sublimation) on exposed surfaces when the air temperature falls below the frost point (the dew point is below freezing)
- 34. an overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land
- 35. in the direction that the wind is blowing
