1. The pressure gradient force dictates that air will travel from regions of high to low pressure. 2. Near the Earth's surface, this horizontal pressure gradient force is directed from higher toward lower pressure. 3. Pressure is used to compute the pressure gradient force in the time-dependent equation for the winds. 4. The pressure gradient force was neglected as it has significant effect only on the updraft in supercells. 5. The geostrophic wind component is the result of the balance between Coriolis force and pressure gradient force . 6. In a hurricane coriolis and Pressure Gradient Force ( PGF ) always opose each other on a quisi-equilibrium. 7. Air naturally moves from areas of high pressure to areas of low pressure, due to the pressure gradient force . 8. A "'geostrophic current "'is an oceanic flow in which the pressure gradient force is balanced by the Coriolis effect. 9. This occurs when external forces such as gravity are balanced by a pressure gradient force . [ 1 ] ." 10. Although the theoretical justification for doing so is weaker, as the pressure gradient force can significantly alter the fluctuating components.
