Do you know how the wind works? The wind is created/made when gases move from high-pressure areas to low-pressure areas, And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. Wind speed increases with increasing height above the ground, starting from zero due to the no-slip condition. Flow near the surface encounters obstacles that reduce the wind speed, and introduce random vertical and horizontal velocity components at right angles to the main direction of flow.
