Name the three driving forces that create and influence the air's motion, and write a brief description of how each creates and/or alters wind
What will be an ideal response?
Pressure gradient: initiates wind flow by directing wind out of high pressure and towards low pressure areas; determines initial wind speed according to the strength of the pressure gradient.
Coriolis: alteration of wind direction caused by the rotation of the Earth. Deflects wind to the right of its original path in the Northern Hemisphere and to the left of its original path in the Southern Hemisphere. Coriolis deflection increases as distance from the Equator increases, and also increases with increasing wind speed.
Friction: Occurs when air molecules drag along the rough surface of the Earth, but decreases as height above the surface increases. Slows the wind speed, and in so doing, also reduces the Coriolis deflection.
