Pressure Gradient Force directed from high to low pressure
The change in pressure measured across a given distance is called a "pressure gradient".
The pressure gradient force acts at right angles to isobars in the direction from high to low pressure. The greater the pressure difference over a given horizontal distance, the greater the force and hence the stronger the wind.
Pressure gradient force: Change in pressure over distance, divided by the air density.
Radar: An instrument used for detecting the presence and distance of objects, such as rain drops, by scattering radio energy.
Pressure Gradient Force A three-dimensional force vector operating in the atmosphere that accelerates air parcels away from regions of high pressure and toward regions of low pressure in response to an air pressure gradient.
Pressure gradient force A force operating in the atmosphere that accelerates air parcels away from regions of high pressure toward regions of low pressure in response to an air pressure gradient.
Pressure Gradient Force- Force acting on air that causes it to move from areas of higher pressure to areas of lower pressure.
Meteorologists refer to the force that starts the wind flowing as the "pressure gradient force." High and low pressure are relative. There's no set number that divides high and low pressure.
We must assume, then, that the pressure gradient forces that we know must act because of the lateral variation in atmospheric pressure are exactly balanced by the Coriolis force, so that we have a time-independent flow.
It is caused by the pressure gradient force that results from high pressure over the eastern pacific and low pressure over Indonesia. The Walker circulation is seen at the surface as easterly trade winds which move water and air towards the west.
Geostrophic wind - 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.
Geostrophic wind 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.
Where there is imbalance between the pressure gradient and Coriolis forces.
When the pressure gradient force is greater than the Coriolis force, the flow takes on a curved path around low pressure.

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.
