The apparent deflection of air masses to the right or left (depending on latitude) as they move from one latitude to another is called the:

Coriolis effect

Explanation:

The Coriolis effect is an apparent force, corresponding to the earth's surface, which makes deflection of any moving object (air masses) to the right in Northern Hemisphere and to the left in Southern Hemisphere because of the earth's rotation. The Coriolis effect is a primary cause of various large scale weather patterns e. g. Coriolis effect is responsible for cyclones and trade winds.

The weather effecting fast moving objects e. g planes, missiles, rockets is affected by the Coriolis effect. Coriolis effect determines the direction of winds. A plane that flies along a path (north-south) should not fly directly towards the target location but it should fly either a little right or left of it to get to the target location.

The Coriolis effect also have an impact on ocean patterns. The winds power the seas. There are very similar patterns of ocean and atmospheric circulation. The effect is that ocean flows in their basins in the Northern Hemisphere and counter clockwise in the Southern Hemisphere.
