Due to unequal distribution of pressure winds blow in perticular direction throughout the year and are reflected due to axial rotation of the earth.This is how planetory wind originates.

The Coriolis Effect
Planetary winds are any winds that occur because of solar radiation. They are in direct correlation to the rotation of the earth. Planetary winds do not blow directly north or south.
Local winds, such as sea breezes and mountain winds, are not planetary winds. These winds are driven by local temperature and pressure differences rather than the global atmospheric circulation patterns that produce the planetary winds.
the trade winds,the westerlies,the polar winds
Planetary scale winds form due to the uneven heating of the Earth's surface by the sun. This causes air to move from high pressure areas to low pressure areas, creating wind patterns that circulate around the globe. Factors such as the Coriolis effect also influence the direction and strength of these winds.

westerlies
Planetary winds do not blow directly north or south due to the Coriolis effect, which is caused by the Earth's rotation. As air moves from high to low pressure, the rotation of the Earth causes the winds to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection results in the winds generally flowing in a more east-west direction, creating prevailing wind patterns such as the trade winds and westerlies. Consequently, the winds follow a curved path rather than a straight north-south trajectory.
