The Coriolis effect (also called the Coriolis force) is defined as the apparent deflection of objects (such as airplanes, wind, missiles, and ocean currents) moving in a straight path relative to the earth's surface.s latitude increases and the speed of the earth's rotation decreases, Coriolis effect increases. A pilot flying along the equator itself would be able to continue flying on the equator without any apparent deflection.
