Q.What is surface wind and what factors affect surface wind?

Surface wind is the wind blowing near the Earth's surface. It is measured by an anemometer (speed) or wind vane (wind direction) at a standard height of 10 m above ground .  The Four Forces That Influence Wind Speed & Wind Direction

Temperature. Air temperature varies between day and night and from season to season due to changes in the heating Earth's atmosphere. .

Air Pressure. Air pressure is the weight of a column of air reaching the top of the atmosphere from the ground. 

Centripetal Acceleration.
