(i) What is Coriolis Effect?
(ii) How does it affect the planetary winds?
Answer
(i) A deflective force that, as a result of the earth's rotation, deflects moving objects to the right in the northern hemisphere and in the left in the southern hemisphere is called coriolis force. This deflective effect of coriolis force is called coriolis effect. It affects the movement of ocean currents and winds.
(ii) The planetary winds do not blow straight from the low pressure belt to high pressure belt but their direction is affected by coriolis force. For example, trade winds in Southern Hemisphere do not blow from south to north but they blow from south-east to north-west.
