what is the most important reason for the origin of wind?briefly discuss the factors determining velocity and direction of wind.
Answers
Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator. Factors determining the velocity and direction of wind are as follows, *Fractional Force- it affects the speed of wind. It is greatest at the surface and it's influence generally extends upto an elevation of 1-3 km. *Coriolis Force- Rotation of Earth about its axis affects the direction of wind. it deflects the wind to the right in the N. hemisphere and vice versa in S. hemisphere.
Answer:
Air temperature is the most important reason behind origin of wind. It is because air temperature determines pressure and due to the pressure difference there is movement of wind from high pressu
