摘要：
The coronal magnetic field evolves in response to motions of the photospheric footpoints of coronal field lines. These motions include the effects of the solar differential rotation, meridional flows, and supergranular diffusion. Simulations have shown that these flows can lead to the formation of highly sheared or helical magnetic fields in the corona. Here we review recent modeling of such non-potential magnetic structures, and we discuss the relevance of these models to observations of filaments and prominences.
