In the northern hemisphere planetary winds deflect to the

Planetary are deflected to right due to Coriolis effect.

Explanation:

The term Coriolis effect is defined as an effect in which the rotating object experience a force called as coriolis force which acts perpendicular to the axis of rotation and direction of motion. The effect talks about how the moving objects like ocean currents, wind are deflected due to the rotation of earth.

Winds and ocean currents are strongly affect by this effect.
