1
• Describe the pattern of air circulation
between an area of low pressure and an
area of high pressure.
– Air moves from regions of high pressure
toward regions of low pressure.
High pressure and low pressure
2
• Explain how the Coriolis effect affects wind
flow.
– In the Northern hemisphere, winds curve to
the right; in the southern hemisphere, they
curve to the left.
Coriolis effect on winds
3
• Name and describe Earth’s three global
wind belts.
– Polar easterlies are prevailing winds that blow
from east to west between 60o and 90o
latitude in both hemispheres.
– The westerlies are winds that blow from the
southwest in the Northern Hemisphere and
from the northwest in the southern
Hemisphere in the belts between 30o and 60o
latitude.

• Name and describe Earth’s three global
wind belts.
– The trade winds are prevailing winds that
blow from the northeast from 30o N to the
equator and from the southeast from 30o S to
the equator.

4
• Summarize the importance of the jet
streams.
– Jet streams are narrow bands of high-speed
winds that blow in the upper troposphere and
lower stratosphere.
– They are important because they can affect
the paths of storms and airline routes.
5
• Identify two factors that create local wind
patterns.
– Temperature differences between land and
sea and between mountains and valleys
influence local wind patterns.

land and sea

• Determine whether wind moving south
form the equator will curve eastward or
westward because of the Coriolis effect.
– Wind moving southward from the equator will
curve to the east because of the Coriolis
effect.
