Description
The helicity is important for quantifying the basic topological configuration of magnetic fields in the solar atmosphere. The distribution of magnetic helicity in the solar atmosphere is presented by means of observational (vector) magnetograms etc. The comparison of other observational helicities with the magnetic one in the solar atmosphere is also an important topic. The diagnostics of helicities provides an important chance for the confirmation of the genaration of magnetic fields from the sub-atmosphere and also solar dynamo models.
