w
All other things being equal, a dry air mass
will be more / less dense than a
moist air mass.
w
All other things being equal, a warm air
mass will be more / less dense
than a cold air mass.
Clouds
w
Dew point is a measurement of
temperature / pressure / elevation.
w
For a cloud to form, the following must take
place:
| Step
1) Liquid water changes to a vapor
(gas) state, undergoing the process
of _______. |
| Step
2) Condensation nuclei
such as ______, ______, or salt
crystals, must be present. |
Step 3)
Temperature of the air containing
water vapor
rises /
falls / remains constant,
causing... (Step 4). |
| Step
4) ...causing the vapor to change to
tiny liquid droplets, undergoing the
process of _______. When
enough of these are present, they
form a cloud. |
| Step
5) The tiny liquid
droplets coalesce around the
condensation nuclei. When a
million droplets have coalesced on a
single nucleus, a _______ forms, and
precipitation may follow. |
w
Sketch each of the following cloud types: cirrus,
cumulus, and stratus.
w
When cumulus
clouds acquire the gray color indicating that
they contain abundant raindrops, they are called
__________________ clouds. When
stratus clouds acquire that color, they
are called __________________ clouds.
Fronts and Precipitation
w
When warm, moist air rises, _______________
results.
w
A front is
___________________________.
w
Name a geographic location where
orographic precipitation is likely to
take place.
w
Convective precipitation
is most likely to take place in
summer / winter.
w
Sketch a "profile" diagram illustrating a
warm front, and label on the diagram
the place where precipitation would occur.
w
New this time:
Sketch a "profile" diagram illustrating a
cold front, and label on the diagram
the place where precipitation would occur.
