Movement of atmosphere parallel to earth’s surface.
A
Air Current
B
Wind
C
Atmospheric Pressure
D
Breeze
Explanation: 

Detailed explanation-1: -Wind is defined as the moving air of atmosphere parallel to earth’s surface (air in horizontal motion). All other masses of air in motion (vertical) should be called as Air Currents.

Detailed explanation-2: -Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth’s own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes.

Detailed explanation-3: -Whereas convection is the vertical movement of air, advection involves the horizontal movement of air and heat energy transference. Temperature differences at the Earth’s surface occur wherever there are differences in surface substances.

Detailed explanation-4: -Coriolis force deflects the air towards the right of the motion (towards east here). The faster air move, the higher the Coriolis force, bending the wind more and more to its right. Eventually, at 5, the two forces cancel each other and the wind flow in a straight line parallel to isobars.

Detailed explanation-5: -But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.
