1) Pressure gradient (differences in air pressure) — air accelerates from high to low pressure; the steeper the gradient (pressure change over distance), the faster the wind.
2) Coriolis effect (Earth’s rotation) — moving air is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, changing wind direction; it balances the pressure gradient at large scales and controls large-scale wind flow (e.g., geostrophic winds).
3) Surface friction and roughness — friction with the ground or obstacles slows the wind and turns it somewhat toward the low-pressure area; its influence is strongest near the surface and on smaller spatial scales.

(Brief note: temperature/solar heating creates the pressure gradients, and on very small or very fast-flowing systems other forces—centrifugal force, local topography—also matter.)
