Vortex flow theory might explain some of it.

There is an interesting series of pix somewhere on the Internet that show some of the most amazing results of a tornado passing through, like the car resting atop a yard fence under the overhang of a house with barely enough clearance room to slip the car under and over. But there is no damage visible to the overhang or the fence!

At the University of Mississippi (or maybe it was Mississippi State) experiments were done to try and drive a 2x4 through different materials without shredding the board. They could not duplicate the board through the tree at any wind speed which would not brake off the tree! I would love to see those experiments repeated in the presence of strong eletrostatic field vortices.
