Across
- 2. A dark, gray cloud bearing rain.
- 5. Winter storm that lasts at least three hours with poor visibility (less than 1/4 mile) and wind speeds of at least 35 mph.
- 6. 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.
- 12. A gauge for recording the speed.
- 13. Temperature at which air is saturated and condensation forms.
- 14. Large, severe storm that forms over tropical oceans, has winds of at least 74 mph, loses power when it reaches land.
- 16. Measure of the amount of moisture held in the air compared with the amount it can hold at a given temperature; can range from 0 percent to 100 percent.
- 18. Amount of water vapor held in the air.
- 19. A large, dark, low altitude cloud.
- 21. A weather system with high atmospheric pressure at its center around which air slowly circulates in a clockwise (northern hemisphere) or counterclockwise (southern hemisphere) direction; calm, fine weather.
- 24. Violent, whirling windstorm that crosses land in a narrow path and can result from wind shears inside a thunderhead.
- 25. vane Mechanical device attached to an elevated structure.
- 27. Line drawn on a weather map that connects points having equal temperature.
- 28. State of the atmosphere at a specific time and place, determined by factors including air pressure, amount of moisture in the air, temperature, wind, and precipitation.
Down
- 1. Boundary between two air masses with different temperatures, density, or moisture; can be cold, warm, occluded, or stationary.
- 3. Instrument used to measure atmospheric pressure.
- 4. The front end or advancing edge of an air mass that will soon replace the air mass that's over a specific region
- 7. Line drawn on a weather map that connect points having equal atmospheric pressure; also indicate the location of high - and low - pressure areas and can show wind speed.
- 8. Radar A radar tracking system using the Doppler effect to determine the location and velocity of a storm, clouds, precipitation, etc.
- 9. A white, globular cloud.
- 10. Water falling from clouds - including rain, snow, sleet, and hail - whose form is determined by air temperature.
- 11. To predict a condition or event on the basis of observations.
- 15. A wispy, white cloud at high altitude.
- 17. Studies weather and uses information from Doppler radar, weather satellites, computers and other instruments to make weather maps and provide forecasts.
- 20. To treat or charge something to the point where no more can be absorbed, dissolved, or retained.
- 22. Truncated cloth cone used as a visual indicator of wind direction.
- 23. A stratus cloud that forms when air is cooled to its dew point near the ground.
- 26. Large body of air that has the same characteristics of temperature and moisture content as the part of Earth's surface over which it formed.
