Weather Terms

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.

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.
