To summarize:

While the winds don't appear to blow down the pressure gradients when viewed from the rotating surface of the Earth, the

• Winds actually do blow from High to Low pressure areas on the Earth.
• The Earth's rotation moves the Highs and Lows making them moving targets for the winds.
  To compensate for this, we apply the Coriolis force to the winds.
• The Coriolis force:
  • is stronger the faster the wind speed
  • is zero at the Equator and strongest at the Poles
  • turns the winds to their right in the Northern Hemisphere and to their left in the Southern Hemisphere
  The Coriolis force only acts on things like the wind which move relative to the Earth's surface. No movement (no wind) - No Coriolis force.
