Coriolis Effect- Northern Hemisphere wind curves winds to the right; in
the Southern Hemisphere wind curves them left.
5. What is the Coriolis Effect?
Because the Earth
rotates on its axis,
circulating air is
deflected toward
the right in the
Northern
Hemisphere and
toward the left in
the Southern
Hemisphere. This
deflection is called
the Coriolis effect.
Coriolis Effect- Northern Hemisphere wind curves winds to the right; in
the Southern Hemisphere wind curves them left.
5. What is the Coriolis Effect?
If the Earth did not
rotate on its axis,
the atmosphere
would only
circulate between
the poles and the
equator in a simple
back-and-forth
pattern.
Coriolis Effect- Northern Hemisphere wind curves winds to the right; in
the Southern Hemisphere wind curves them left.
