14-13
The trade winds (yellow)
blow
toward
the
west near the
Equator,
while the prevailing westerlies (white) blow
east
toward the polar zones.
These winds push the
surface
waters
along, creating great circular gyres (blue) in each
ocean
basin north and south of the
Equator. The wind
patterns and ocean gyres
result from
the Coriolis effect.
