The Coriolis effect is an inertial force that acts on objects that are in motion within a frame of reference that rotates with respect to its inertial frame. Any reference frame with clockwise rotation, the force acts to the left of the motion of that object; and vice versa.
Since the the earth rotates on a 23° axis, circulating air is deflected towards the right in the northern hemisphere and towards the left in the southern hemisphere.
Because the air is moving in a curved path creating circular spin patterns as the air travels from areas of high pressure to low pressure.
And so that’s why hurricanes in the north rotate counterclockwise, and tropical cyclones in the south rotate clockwise.
