Document Summary
2 other forces are effecting wind flow: coriolis effect, friction the coriolis effect(force): Objects in the atmosphere are influenced by earth rotation. Overall the result is a deflection of moving objects to the right in the northern hemisphere and to the left in the southern hemisphere. Coriolis deflection increaseed from 0 at the equator to a maximum at the poles. The delfective force also increases with speed of the moving object. Takes place regardless of the direction of motion: produce an apparent deflection(right in nh, left in sh) in all moving objects regardless of their direction. 2. 0 at equator and increase with latitude: increase with object"s speed. 4. does not change object speed only direction friction: A force of opposition which slows air in motion. Initiated at the surface and extend, decreasingly, aloft. Impt for air within 1. 5 km(1mi) of the surface, the planetary boundary layer. Because friction reduces wind speed it also reduces coriolis force.
