Q’S
Did you write in COMPLETE
SENTENCES?!?!
Wind is always named by where it is
coming from!
What would a wind be named (North
or South) if it is blowing from Georgia
to Florida?
It is called a NORTH wind because it is
moving from the north to the south.
Most often noticed at the beach!

Land heats up faster than water.
Warm air over land rises.
Air over water moves to shore.
Would occur during the day.
Named a SEA breeze because it comes from the
sea.

Land cools off faster than water.
Warm air over water rises.
Cool air from land takes its place.
Would occur at night.
Called a LAND breeze because the wind is
coming from the land.
CLOSER LOOK AT LOCAL WIND
When Air WARMS up
 When air heats up, it loses mass and becomes less
dense.
 The air becomes more spread out
 Because of this, warm air will rise
When Air COOLS down
 When air cools down, it gains mass and becomes
more dense
 The air will sink
Look at these
two diagrams.
Can you tell
which is the
land breeze
and which is
the sea
breeze?

1. Blow steadily
from the same
direction all the
time.
2. The path is curved
because of the
Coriolis Effect.

TYPES OF GLOBAL WINDS
A.
B.
C.
Polar easterlies
Westerlies
Trade winds
POLAR EASTERLIES
From
the POLES
Wind belts that extend from
the poles to 60° latitude
Formed from cold sinking
air moving from the poles
creating cold temperatures
WESTERLIES
Wind
belts found between
30° and 60° latitude
Flow towards the poles
from west to east carrying
moist air over the Unites
States
TRADE WINDS
Winds
that blow from 30°
almost to the equator
Called the trade winds
because of their use by early
sailors
Jet Stream
1. Very fast 200-400
kmh
2. Acts like a conveyor
belt
3. Goes completely
around the earth.
4. In US, it makes
weather generally
blow east to west
5. Measured by
anemometer
Notice that the jet stream does not stay the same
every day. But it is always there!
Notice on this weather map in motion
how the rain moves toward the east
over time.

Air over land is cooler and forms an area of high
pressure. The cool air moves toward the ocean.
Polar Easterlies
Generally moves over short distances
Jet stream
Caused by unequal heating over a large area
Can blow from any direction
Land breeze
Is effected by the Coriolis Effect
Caused by unequal heating within a small area
Valley breeze

The Doldrums
Blows from a specific direction from day to day
Sea breeze
Horse latitude
Effected by local geographic features
Westerlies
Caused because the angle of the sun giving the
equator more direct sunlight
Mountain breeze
Trade winds
During the day, air over the ocean is cooler and
forms an area of high pressure. The cool air
flows to the land
