Across
- 4. falling from clouds including rain snow sleet and hail whose form is determined by air temperature.
- 5. lines drawn on a weather map that connects points having equal atmospheric pressure also indicate the location of high and low pressure areas and can show wind speed.
- 7. boundary between two air masses with different temperatures density or moisture can be cold warm occluded and stationary.
- 10. large serve storm that forms over tropical oceans has winds of at least 120 km/h and loses power when it reaches land.
- 13. winter storm that least three hours with temperature of -12 or below poor visibility and winds of at least 51 km/h
- 14. amount of water vapor held in the air.
- 15. studies weather and uses information from Doppler radar weather satellites computers and other instruments to make weather map and provides forecasts.
Down
- 1. line drawn on a weather map that connects points having equal temperature.
- 2. a status cloud that forms when air is cooled to its dew point near the ground.
- 3. 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.
- 6. violent whirling windstorm that crosses land in a narrow path and can result from wind shears inside a thunderhead.
- 8. mass- large body of air that has the same characteristic of temperature an moisture content as the part of earth surface over which it formed.
- 9. point- temperature at which air is saturated and condensation forms.
- 11. humidity-measures 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.
- 12. model-indicates weather conditions at a specific locations using a combination of symbols on a map.
