Across
Down
2. the short-term state of the atmosphere,
including temperature, humidity,
precipitation, wind, and visibility
3. an instrument that measures air pressure
4. at constant pressure and water vapor
content, the temperature at which the rate of
condensation equals the rate of evaporation (2
words)
5. an instrument that measures and displays
temperature
9. the distance at which a given standard
object can be seen
12. the movement of air caused by differences
in air pressure
14. an instrument that is used to measure
relative humidity
15. an instrument used to measure wind speed
17. the amount of water vapor in the air
20. a feathery cloud that is composed of ice
crystals and that has the highest altitude of
any cloud in the sky (2 words)
23. the ratio of the amount of water vapor in
the air to the amount of water vapor needed to
reach saturation at a given temperature (2
words)
27. occurs when cold air is above warm water
and evaporation directly over the water occurs
in the form of steam (2 words)
28. of vertical development - clouds that rise
up to 12,000 m high commonly formed by the
rapid lifting of moist, warm air
1. how hot or cold something is
6. an area where the atmospheric pressure is
greater than the surrounding area; the air
sinks, warms and usually produces clear
weather (3 words)
7. system an area where the atmospheric
pressure is lower than the surrounding area;
the air rises, cools, and usually produces rainy
weather (3 words)
8. the prefix for “rain”; e.g. nimbostratus
clouds are rain clouds
10. a gray cloud that has a flat/ uniform base
and that commonly forms a very low altitudes
(2 words)
11. the boundary between air masses of
different densities and usually different
temperatures
13. any form of water that falls to Earth from
clouds
16. a low-level, billowy cloud that commonly
has a top that resembles cotton balls and a
dark bottom (2 words)
18. (sea fog) occurs when warm, moist air
moves across cold water and is cooled to its
dew point (2 words)
19. (ground fog) occurs when Earth’s surface
cools and the moist air near the ground cools
to its dew point (2 words)
21. the state or process that occurs when no
more of something can be absorbed,
combined with, or added
22. the measure of the force with which air
molecules push on a surface (2 words)
29. long-distance winds that travel above
global winds for thousands of kilometers (2
words)
24. a large body of air throughout which
temperature and moisture content are similar
(2 words)
25. a collection of small water droplets or ice
crystals suspended in the air, which forms
when the air is cooled and condensation
occurs
26. a cloud that forms near the ground and
results in the reduction of visibility
