\nThe Pressure Gradient Force (PGF) is the primary force that initiates air movement, i.e., wind. It is the force that pushes air from areas of high pressure to areas of low pressure. The strength of the wind is directly proportional to the magnitude of the pressure gradient (the rate of pressure change over distance).
\n<\/section>\n
\nPressure gradient force is fundamental to atmospheric circulation. Air flows from high pressure to low pressure, and this movement constitutes wind. Other forces like Coriolis force and friction modify the direction and speed of the wind, but PGF is the initial driver.
\n<\/section>\n
\nWhile other forces influence wind, their roles are different: Gravitational force keeps the atmosphere bound to the Earth. Centrifugal force is relevant in curved motion but not the primary cause of wind. Frictional force acts opposite to the direction of motion, slowing down the wind, especially near the surface.
