Across
- 1. large body of air that has the same characteristics, temperature and moisture content as the part of Earth's surface over which it formed.
- 4. measure of they amount of moisture held in the air compared with the amount it can hold at a given temperature; can range from zero percent to one-hundred percent
- 5. to predict a condition or event on the basis of observations
- 6. studies weather and uses information from Doppler radar, weather satellites computers and other instruments to make weather maps and provide forecasts.
- 7. amount of water vapor held in the air
- 9. winter storm that lasts at least three hours with temperatures of-12 Degrees C or below, poor visibility, and winds of at least 32 miles per hour
- 13. boundary between two air masses with different temperatures, density, or moisture; can be cold, warm, occluded, and stationary.
- 14. an tool used to measure atmospheric pressure
- 15. water falling from clouds - including rain, snow, sleet, and hail - whose form is determined by air temperature
- 17. violent, whirling wind storm that crosses land in a narrow path and can result from wind shears inside a thunder head
Down
- 2. indicates weather conditions at a specific location, using a combination of symbols on a map.
- 3. temperature at which air is saturated and condensation forms
- 8. 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
- 10. Line that shows equal atmospheric pressure on a map.
- 11. something that influences a result
- 12. large, severe storm that forms over tropical oceans, has winds of at least 75mp/h (120km/h), and loses power when it reaches land.
- 13. a stratus cloud that forms when air is cooled to its dew point near the ground
- 16. line drawn on a weather map that connects points having equal temperature
