For those who did not, in physics, the Coriolis force is an inertial force that acts on objects that are in motion relative to a rotating frame of reference.
The Coriolis force is perpendicular to the object's axis. The Earth spins on its axis from west to east The Coriolis force, therefore, acts in a north-south direction. The Coriolis force is zero at the Equator.
Deflection of an object due to the Coriolis force is called the The Coriolis Effect EQUATOR
The mathematical expression for the Coriolis force appeared in an 1835 paper by French scientist Gaspard Gustave de Coriolis.
When Newton's laws are transformed to a rotating frame of reference, the Coriolis force and Centrifugal force appear Rotating Earth Centrifugal Force Weight EQUATOR
Axis North Pole In popular usage of the term "Coriolis effect" the rotating reference frame implied is almost always the Earth. Because the Earth spins, Earth-bound observers need to account for the Coriolis force to correctly analyze the motion of objects. .Direction of Spin South Pole
Effect on weather pattern
The development of weather patterns, such as cyclones and trade winds, are examples of the impact of the Coriolis effect.
