Coriolis Force
q  First, Point A rotates faster than Point B (UA > UB)
q  When A arrives at the latitude of B, it will have a new zonal velocity (Unew)
     faster than its original velocity UA
č Unew > UA > UB
č  A northward motion starting at A will arrive to the east of B
č  It looks like there is a “force” pushing the northward motion toward right
č  This apparent force is called “Coriolis force”:
              Coriolis Force = f V
       where f = 2*W*Sin(lat)  and W=7.292x10-5 rad s-1
