    spanwise vortices and induced drag

    What are spanwise vortices (I've seen the term used in a few places but never defined) and how do they relate to induced drag? In this explanation of induced drag: http://selair.selkirk.bc.ca/aerodynamics1/Drag/Page6.html what causes the 'flow circulation' in the 6th picture? Thanks
