Weather Puzzle

5. A flood that occurs within a few hours heavy or excessive rainfall, dam or levee failure or water released from an ice jam.
8. The leading edge of a warm air mass that is displacing the colder air ahead of it.
10. An atmospheric layer that contains a high proportion of oxygen that exists as ozone
11. A condition that occurs when water overflows the natural or artificial confines of a stream or river; the water also may accumulate by drainage over low-lying areas.
13. The percentage of water vapor in the air compared to how much could be there.
16. The apparent temperature to the human body based on both air temperature and wind speed.
18. A boundary that separates two different air masses exhibiting little or no movement.
20. An instrument used to measure rainfall amounts.

1. A region of air with higher barometric pressure and clockwise winds; usually associated with fair weather.
2. Mid-altitude clouds with a cumuliform shape.
3. The actual pressure value indicated by a pressure sensor.
4. A small-scale current of rising air. This is often associated with cumulus and cumulonimbus clouds
6. A region of air with lower barometric pressure and counter-clockwise winds; usually associated with stormy weather.
7. Sky condition when greater than 9/10 of the sky is covered by clouds.
9. The blanket of air surrounding earth.
12. The temperature to which air must be cooled in order for it to be saturated. If skies are clear, dew will form.
14. The leading edge of a cold air mass that is displacing the warmer air ahead of it.
15. The apparent temperature to the human body based on both air temperature and the amount of moisture present in the air.
17. Strong winds in the higher levels of the atmosphere that separate areas of different temperatures and act as steering currents for fronts.
19. A cooling of the equatorial waters in the Pacific Ocean.
