Across
- 7. 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.
- 8. Large, severe storm that forms over tropical oceans, hinds of at least 120 km/h and loses power when it reaches land.
- 10. Indicates weather conditions at a specific location, using a combination of symbols on a map.
- 11. Boundary between two air masses with different temperatures, density, or moisture; can be cold, warm, occluded, and stationary.
- 12. Violent, whirling windstorm that crosses land in a narrow path and can result from wind shears inside a thunderhead.
- 14. 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.
Down
- 1. Water falling from clouds- including rain, snow, sleet, and hail- whose form is determined by air temperature
- 2. Amount of water vapor held in the air.
- 3. Winter storm that lasts at least three hours with temperature of -12 degrees Celsius or below. Poor visibility; and winds of at least 51 km/h.
- 4. 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.
- 5. Large body of air that has the same characteristics of temperature and moisture content as the part of Earth’s surface over which it is formed.
- 6. Studies weather and uses information from Doppler radar, weather satellites, compouters, and other instruments to make weather maps and provide forecasts.
- 9. A stratus cloud that forms when air is cooled to its dew point near the ground.
- 13. Temperature at which air is saturated and condensation forms.
