Abstract
From an analysis of substantial sets of vector magnetograms, we have found that the development of magnetic shear is intrinsically related to the emergence of new magnetic flux. In view of the magnetic environment of the new emerging flux, we further divided the scenario of shear development into four modes: (1) satellite dipole intrusion; (2) collision of two dipoles; (3) unusual flux emergence in greatδ-sunspots; (4) flux emergence in the active center of an active region. From a physical point of view, magnetic shear is either generated by local dynamo effect, or by the upward transport of magnetic shear from a subphotospheric layer.
