2. Winds blown in one direction over the earth’s
surface.
• Easterly winds
• Westerly winds

3. The most frequent wind direction that a
location experiences.

4. Prevailing winds effect the climate of a
landmass by blowing over warm or cold oceans.

6.  Southwest coast of Africa is cooled by the
Benguela current.

7.  The south Atlantic ocean is cold and warm in
some places
Warm Prevailing
because winds can

equator. because it
The south pushes the
equatorial current away
spreads warm from the
water to south shore
and north
America

8. The prevailing
winds cause the
current to move
which makes the
extra water fill
up in the area,
making the
benguela current
cold.

9. This is why
the benguela
current is
cold, this
therefore
makes that
region of land
cooler then
other parts of
Africa.

10. This shows that
the prevailing
winds will be
warm because the
Indian ocean is
warm.

11.  The earth is encircled by broad prevailing
wind belts which are separated by regions of
subsidence and ascent.
 ascent is when the wind rises up into the air
and subsidence relates to how the wind
lowers down and these changes are due to
the change of pressure.
 The direction and location of these wind belts
are controlled by the rotation of the earth and
solar radiations

12. A region of subsidence
because the air is
lowering due to the
change of pressure.
A region of ascent:
the wind current
rises up from the
sun’s rays.
