The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise.

In physics, the Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame.

This point of view difference is illustrated clearly by animations in the 3753 Cruithne and Coriolis effect articles.

Section dm < sub > 1 </ sub >, therefore, has a lot of angular rotating velocity with respect to the rotation around the pivot axis, and as dm < sub > 1 </ sub > is forced closer to the pivot axis of the rotation ( by the wheel spinning further ), due to the Coriolis effect dm < sub > 1 </ sub > tends to move in the direction of the top-left arrow in the diagram ( shown at 45 °) in the direction of rotation around the pivot axis.

* Inertial waves, which occur in rotating fluids and are restored by the Coriolis effect ;

The resulting horizontal pressure gradient accelerates the air from high to low pressure, creating wind, and Earth's rotation then causes curvature of the flow via the Coriolis effect.

While large-scale storms always rotate cyclonically due to the Coriolis effect, thunderstorms and tornadoes are so small that the direct influence of the Coriolis effect is unimportant, as indicated by their large Rossby numbers.

The knowledge of wind patterns and currents, the trade winds and the oceanic gyres in the Atlantic, and the determination of latitude led to the discovery of the best ocean route back from Africa: crossing the Central Atlantic to the latitude of the Azores, using the permanent favorable winds and currents that spin clockwise in the Northern Hemisphere because of atmospheric circulation and the effect of Coriolis, facilitating the way to Lisbon and thus enabling the Portuguese venturing increasingly farther from shore, the maneuver that became known as the " volta do mar " ().

The rotation of the Earth has profound effects on the Earth's fluid dynamics, often due to the Coriolis effect.

* 1835-Gaspard Coriolis examines theoretically the mechanical efficiency of waterwheels, and deduces the Coriolis effect.

Movement is due to the pressure gradient force ( horizontal differences in atmospheric pressure ) and the Coriolis effect, caused by the earth spinning about its axis.

* Gustave-Gaspard Coriolis, gave his name to the Coriolis effect

If objects are seen as moving within a rotating frame, this movement results in another fictitious force, the Coriolis force ; and if the rate of rotation of the frame is changing, a third fictitious force, the Euler force is experienced.

Unlike the other two fictitious forces, the centrifugal force always points radially outward from the axis of rotation of the rotating frame, with magnitude, and unlike the Coriolis force in particular, it is independent of the motion of the particle in the rotating frame.

This force is the sum of an outward centrifugal force and an inward Coriolis force.

When the angular velocity of this co-rotating frame is not constant, that is, for non-circular orbits, other fictitious forces — the Coriolis force and the Euler force — will arise, but can be ignored since they will cancel each other, yielding a net zero acceleration transverse to the moving radial vector, as required by the starting assumption that the vector co-rotates with the planet.

However, the observer ( red dot ) who is standing in the rotating ( non-inertial ) frame of reference ( lower part of the picture ) sees the object as following a curved path due to the Coriolis and centrifugal forces present in this frame.

The Coriolis force is proportional to the rotation rate and the centrifugal force is proportional to its square.

The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame.

Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as large-scale movement of air in the atmosphere or water in the ocean.

Such motions are constrained by the 2-dimensional surface of the earth, so only the horizontal component of the Coriolis force is generally important.

( The first extra term is the Coriolis force, the second the centrifugal force, and the third the Euler force.

But in a frame rotating about a fixed axis, the object appears to move in a circle, and is subject to centripetal force ( which is made up of the Coriolis force and the centrifugal force ).

There are two approaches to this resolution: one approach is to look for the origin of the fictitious forces ( the Coriolis force and the centrifugal force ).

For any inertial frame, the Coriolis force and the centrifugal force disappear, so application of the principle of special relativity would identify these frames where the forces disappear as sharing the same and the simplest physical laws, and hence rule that the rotating frame is not an inertial frame.

If the spheres only appear to rotate ( that is, we are watching stationary spheres from a rotating frame ), the zero tension in the string is accounted for by observing that the centripetal force is supplied by the centrifugal and Coriolis forces in combination, so no tension is needed.

A Coriolis effect, caused by the overall planetary rotation, tends to organize the flow into rolls aligned along the north-south polar axis.

Rotation in the outer core is supplied by the Coriolis effect caused by the rotation of the Earth.

An ocean current is a continuous, directed movement of ocean water generated by the forces acting upon this mean flow, such as breaking waves, wind, Coriolis effect, cabbeling, temperature and salinity differences and tides caused by the gravitational pull of the Moon and the Sun.

The divergence or diffluence in the upper atmosphere caused by the Jet Stream removes and disperses the rising air at a faster rate than it is replaced at the surface, which, along with the Coriolis Force, creates and develops a storm.

The Coriolis force caused by the Earth's rotation is what gives winds within low-pressure systems their counterclockwise circulation in the northern hemisphere ( as the wind moves inward and is deflected right from the center of high pressure ) and clockwise circulation in the southern hemisphere ( as the wind moves inward and is deflected left from the center of high pressure ).

Gyres are caused by the Coriolis Effect ; planetary vorticity along with horizontal and vertical friction, which determine the circulation patterns from the wind curl ( torque ).

However, the Coriolis effect caused by the rotation of Earth causes winds to steer to the right of what would otherwise be expected across the Northern Hemisphere, and left of what would be expected in the Southern Hemisphere.

The Rossby parameter ( or simply beta ) is a number used in geophysics and meteorology which arises due to the meridional variation of the Coriolis force caused by the spherical shape of the Earth.

However, four fictitious forces are defined for frames accelerated in commonly occurring ways: one caused by any relative acceleration of the origin in a straight line ( rectilinear acceleration ), two caused by any rotation ( centrifugal force and Coriolis force ) and a fourth, called the Euler force, caused by a variable rate of rotation, should that occur.

Because the propagation of the wave is fundamentally caused by an imbalance of the forces acting on the air ( which is often thought of in terms of air parcels when considering wave motion ), the types of waves and their propagation characteristics vary latitudinally, principally because the Coriolis effect on horizontal flow is maximal at the poles and zero at the equator.

An ocean current is generated by the forces such as breaking waves, terms of temperature and salinity differences, wind, Coriolis effect, and tides caused by the gravitational pull of the Moon and the Sun.

Rossby waves caused by this jet stream shear and the Coriolis force cause it to meander.
