Learn how the Coriolis force affects the motion of objects in a rotating reference frame, such as the Earth. Find out the equation, the right hand rule, and the examples of this force in meteorology and mechanics. Deflection of an object due to the Coriolis force is called the Coriolis effect. Though recognized previously by others, the mathematical expression for the Coriolis force appeared in an 1835 paper by French scientist Gaspard-Gustave de Coriolis, in connection with the theory of water wheels. The Coriolis force is an apparent force that arises from the rotation of the Earth, affecting the motion of objects moving within a rotating frame of reference. Here are the key aspects of the Coriolis force : Definition – The Coriolis force is described as an inertial force that acts on objects in motion within a rotating coordinate system. It causes moving objects to follow a curved path rather than a straight line due to the rotation of the Earth. Direction of Deflection – In the ... 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 ...
