Coriolis Effect

There are 2 Earth Rotation Effects that are of interest in external ballistics.  Both are a subset of what is known mathematically as Coriolis Acceleration.  The Coriolis Effect of ballistics manifests itself as an apparent drift to the right of the target in the Northern Hemisphere, and to the left in the Southern Hemisphere.  It affects shots in all directions and depends only on latitude.  It has maximum impact at the poles, and the effect is zero at the equator.

deflection (ft) = 0.000072722 * distance(ft) * Sin(latitude) * time of flight(seconds)
