The theoretical wind generated when pressure gradient forces are exactly balanced by the Coriolis force. Most atmospheric motions are not geostrophic, due to frictional and other effects.

The calculated or measured wind that occurs when the pressure gradient acceleration equals the Coriolis acceleration. The geostrophic wind is seen above the boundary layer, in the upper layers of the atmosphere.

defined as the (theoretical) wind that would blow on a rotating planet which results from a balance between the pressure gradient causing the initial displacement of the air, and the apparent (to us on the earth) deflecting force due to the planetary rotation. Many corrections are needed to find the 'true' wind vector amongst which are the effects of friction and the several forces involved when the pressure pattern changes - which is the usual case. However, by this definition we get the general statement that the speed of the geostrophic wind is proportional to the pressure gradient, or inversely proportional to the distance between isobars/contours. Curvature of the flow must also be taken into account ... see Gradient wind.

In meteorology, the theoretical wind resulting from the balance of the pressure gradient force and the geostrophic force. Analogous to the geostrophic current in oceanography.

A theoretical horizontal wind blowing in a straight path, parallel to the isobars or contours, at a constant speed. The geostrophic wind results when the coriolis force exactly balances the horizontal pressure gradient force.

The wind that occurs through a balance of pressure gradient and Corriolis forces

The horizontal wind for which the coriolis acceleration (caused by the Earth's rotation) exactly balances the horizontal pressure force. In practice it is assumed that this marks the upper limit of frictional influence of the Earth's surface. The geostrophic wind blows along the contours on a constant pressure surface. The speed of the geostrophic wind is dependent upon how close your pressure contour are together. Thus, when your pressure contours are close together, you will see a strong geostrophic wind. The opposite occurs when your pressure contours are far apart.

A wind that is balanced by the Pressure Gradient Force and Coriolis. To remain in geostrophic balance the wind needs to occur in the middle or high latitudes (since Coriolis is strong enough there) and needs to flow at a constant speed and direction (to prevent ageostrophic accelerations and centrifugal accelerations).

That horizontal wind velocity at which the Coriolis acceleration exactly balances the horizontal pressure force. It is directed along contour lines or isobars.

A wind that is affected by coriolis force, blows parallel to isobars and whose strength is related to the pressure gradient (i.e., spacing of the isobars).

Wind that flows parallel to the isobars in a straight line; a balance between the pressure gradient force and the coriolis force. The pressure gradient force is balanced by the Coriolis force in the geostrophic balance.

When the wind is steady, horizontal, and flowing parallel to straight isobars it is called the geostophic wind. Where the Pressure Gradient force is exactly balanced by the Coriolis force.

theoretical wind which results from the equilibrium between horizontal components of the pressure gradient force and the coriolis force (deviating force) above the friction layer; only these two forces (no frictional force) are supposed to act on the moving air; it blows parallel to straight isobars or contours.

A steady horizontal motion of air along straight, parallel isobars or contours in an unchanging pressure or contour field. It is assumed that there is no friction, that the flow is straight with no curvature and there is no divergence or convergence with no vertical acceleration.

The geostrophic wind is defined as the wind resulting from what is called the geostrophic balance between the Coriolis force and the pressure gradient force acting on a parcel of air, causing the wind to blow parallel to isobars of pressure in the earth's atmosphere. Such a wind is a zero-frequency inertial wave. However, this balance is rarely found exactly in nature, due to other forces acting on the wind, such as friction from the ground, or the centrifugal force from curved fluid flow.
