Coriolis Effect

The apparent deflection of moving objects when the motion is described relative to a rotating reference frame

The main cause of the Coriolis effect is...

the rotation of the Earth

The direction of deflection is...

from the origin of movement

As latitude increases and the speed of the earth's rotation decreases

Coriolis effect increases

The Coriolis effect is greater at...

the poles

The Coriolis effect is the least at...

the equator

the faster the speed of the object...

the greater the Coriolis effect

Coriolis is greatest at the poles and least at the equator due to

conservation of angular momentum

The rotational axis is least at the poles therefore

Coriolis is greater

Momentum before has to =

the momentum after

Currents are named

For the direction they flow towards

Equator=

Greatest speed

Poles=

Slowest speed

In the northern hemisphere storms rotate...

Counterclockwise because in a low pressure system the air traveling from outside the system to inside the system (high pressure to low pressure) deflect to the right which causes counter clockwise rotation of storms. (refer to picture)

In the southern hemisphere storms rotate...

clockwise because in a low pressure system the air traveling from outside the system to inside the system (high pressure to low pressure) deflect to the left which causes clockwise rotation of storms. (refer to picture)
