Notes for Weather
TYPES OF CLOUDS:
3 major types of clouds: ________________, ________________, ________________.
Stratus- lower clouds that are wider than they are tall
Cumulus- Mid-level clouds that are generally puffier and create storms.
Cirrus- high level clouds that hardly effect weather.
Cumulonimbus are ________________ clouds with great vertical growth.
(Thunderheads)
Clouds have lots of ________________ that create heat as they condense water
from vapor.
Humid air is ________________ than dry air.
PRESSURE SYSTEMS
________________ is the concentration of air molecules
in an area. These systems are steered by the
________________.
________________ pressure is when there are more molecules.
An ________________ is a mass of air with similar
characteristics, such as temperature and dew point.
A division between two air masses is a ________________.
A front is a type of boundary between two air masses of different
________________.
A low pressure system is characterized by ________________ motion and lousy
weather.
Counter clockwise motion is also called
________________ , pulling air in and up.
________________ pressure systems have a clockwise motion and good weather.
Clockwise motion is also called ________________ and
moves air down and out of the center.
When air moves up in a low pressure system, the air
particles create ________________.
SOURCES OF AIR MASSES:
1. ________________ is a cold, dry air mass that forms over large area of land.
2. ________________ is a warm, dry air mass that forms over large area of land.
3. ________________ is a cold, moist air mass that forms over larger body of water.
4. _______________ is a warm, moist air mass that forms over larger body of water.
5. ________________ is a super cold, dry air mass that comes from the polar region.
FRONTS
________________ forms when a cold air mass (more dense) pushes a warm air
mass upward causing ________________. Southside of a Low Pressure system and
tend to move in a ________________ direction.
________________ forms when a warm air mass advances and moves over a cold
air mass. Tend to extend east of a low pressure system.
________________ forms when two air masses push against each other without
moving.
________________ forms when cold front “catches up” with a warm front.
Boundary between dry and moist air masses is known as a ________________.
Tends to cause the greatest disruption and “piling” of air to create severe
thunderstorms.
LAYERS OF THE ATMOSPHERE
________________ - We live here, ______ of atmosphere mass, contains all most all
of the carbon dioxide, water vapor, clouds, air pollution, and ___________.
Temperature ____________ the higher the altitude.
________________ -Contains the Ozone Layer which protects us from ultraviolet
radiation, air is very __________, very cold at the start of this layer (-60C),
temperature ________________ with altitude.
___________________ -Coldest layer (-93C), meteors burn up in this layer, wind
storms (winds up to 320km/h), temperature ___________ with altitude.
____________________ - Temperature can reach up to 1,700C, lack of particles
cause object to not feel heat, temperatures ________________ with altitude.
_________________- Gases become electrically charged because
of high temperatures, reflect radio waves, nitrogen and oxygen absorb harmful
solar energy.
__________________-Highest layer, satellites orbit here.
