The Coriolis effect describes the pattern of deflection taken by objects not firmly connected to the ground as they travel long distances around Earth. The Coriolis effect is responsible for many large-scale weather patterns. The key to the Coriolis effect lies in Earth’s rotation. Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 ... An object attempting to move into or out of a rotating reference frame will experience 2 apparent forces: one outward (centrifugal) and one sideways ( Coriolis ). The Coriolis effect is used to describe the Coriolis force experienced by the moving objects such that the force is acting perpendicular to the direction of motion and to the axis of rotation. The Coriolis effect is the observable phenomenon that results from the Coriolis force . It’s why weather patterns, ocean currents, and even long-range artillery shots don’t go exactly where you’d expect them to if Earth were standing still.
