Across
- 2. winter storm that lasts at least three hours with temp. of -12 c or below, poor visibility and winds of at least 51 km/h.
- 6. a stratus cloud that forms when air is cooled to its dew point near the ground.
- 7. state of the atmosphere at a specific time and place, determined by factors including air, temp., wind and precipitation.
- 8. lines 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
- 9. water falling from clouds including rain,snow,sleet,and hail whose form is determined by air temp.
- 13. model indicates weather conditions at a specific location, using a combination of symbols on a map.
- 14. amount of water vapor held in the air.
- 15. boundary between two air masses with different temps., density, or moisture; can be cold, warm, occluded, and stationary.
Down
- 1. studies weather and uses information from Doppler radar, weather satellites, computers, and other instruments to make weather maps and provide forecasts.
- 3. violent, whirling windstorm that crosses land in a narrow path and can result from wind shears inside a thunderhead.
- 4. large, severe storm that forms over tropical oceans, has winds of at least 120 km/h, and loses power when it reaches land.
- 5. point temp. at which air is saturated and condensation forms.
- 10. humidity measure of the amount of moisture held in the air compared with the amount it can hold at a given temp; can range from 0% to 100%.
- 11. line drawn on a weather map that connects points having equal temps.
- 12. mass large body if air that has the same characteristics of temp. and moisture content as the part of earths surface over with it formed.
