The force is perpendicular to the wind and current. It acts to the right of the flow looking downstream in the northern atmosphere. Almost always the Coriolis force is balanced by the pressure gradient and the force does not cause any movement. Remember only unbalanced force cause movement. The two forces are in balance.
Coriolis force balances Pressure force in oceans .
Currents bumping into the continents must change direction and flow toward the equator or the pole. . A pressure gradient is a change of pressure across a horizontal distance. Water that is piled up in a mound creates a zone of high pressure. The steeper the water slide or snow hill, the faster you'll go down. The less steep, the less speed the water or you will have.
