The Venturi effect makes speed inversely proportional to pressure - I'm assuming there isn't enough pressure [as the turbine generator harvests most of it] to take the wind back up into the intakes. Also I don't know how much gravitational forces are at play with relation to winds - but bear in mind wind is nothing more than the movement of gasses and as such can be treated as a fluid, so I'm assuming gravity aids the Venturi effect, but must be fought against if you want the wind to go back to the intake.
