In areas away from tropics (high Coriolis force) geotrophic wind is a steady wind which is a balanced motion where :
Pressure gradient force is balanced by Coriolis force
The geostrophic wind is an idealised steady, frictionless, straight-line flow found in the free atmosphere at middle and high latitudes.
In it the pressure gradient force, directed from high to low pressure, is exactly balanced by the Coriolis force acting in the opposite direction, so the wind blows parallel to the isobars.
A balance of pressure gradient force with centripetal force describes cyclostrophic flow, as in tornadoes near the equator, while involving all three forces gives the gradient wind around curved isobars.
Since the Coriolis force is large away from the tropics, the two-force geostrophic balance is a very good approximation there.
Hence, Pressure gradient force is balanced by Coriolis force.
