  Through the enhancement of transport, turbulence is expected to contribute to
the fast reconnection. However the effects of turbulence are not so
straightforward. In addition to the enhancement of transport, turbulence under
some environment shows effects that suppress the transport. In the presence of
turbulent cross helicity, such a dynamic balance between the transport
enhancement and suppression occurs. As this result of dynamic balance, the
region of effective enhanced magnetic diffusivity is confined to a narrow
region, leading to the fast reconnection. In order to confirm this idea, a
self-consistent turbulence model for the magnetic reconnection is proposed.
With the aid of numerical simulations where turbulence effects are incorporated
in a consistent manner through the turbulence model, the dynamic balance in the
turbulence magnetic reconnection is confirmed.
