Q.
Moisture
in the Air: Moisture
enters the air through the evaporation of water. Water
vapor, or moisture, in the air is called humidity.
Relative humidty
is the percentage of moisture the air holds relative to the
amount it could hold at a particular temperature.
Meterologists measure relative humidity with a psychrometer.
R.
Clouds:
Clouds form when moisture in the air condenses on small
particles of dust or other solids in the air.
3 TYPES OF CLOUDS:
1.
Cumulus Clouds:
Fluffy
and white with
flat
bottems,
indicates fair weather. When cumulus clouds get
larger and darker
on the bottem, they produce thunderstorms.
2.
Stratus Clouds:
Are smooth, gray clouds
that cover the whole sky and block out the sun, rain, or
snow.
3. Cirrus
Clouds: Called mare's
tails, wispy clouds, usually fair weather, but they often indicate
that rain
or snow
will fall in several hours.
S.
Precipitation:
Water that falls from the atmosphere to the Earth in the
form of rain, sleet,
snow, or hail.
Precipitation in the form of rain is measured
with a rain gauge.
