Surface friction
winds at the surface
- are at an angle across the isobars due to the stronger pressure gradient
friction does not affect pressure gradient force which turns the wind at an angle across the isobars toward lower pressure until the three forces balance (incl Coriolis force)
- Coriolis force is weaker
- 4105
2,000 feet above the surface
- speed is greater and the direction is usually parallel to the isobars
- veer to the right of the surface winds
- PGF
- Coriolis force/effect
