Abstract: | From a large number of SOHO/MDI longitudinal magnetograms, three physical measures including the maximum horizontal gradient,
the length of the neutral line, and the number of singular points are computed. These measures are used to describe photospheric
magnetic field properties including nonpotentiality and complexity, which is believed to be closely related to solar flares.
Our statistical results demonstrate that solar flare productivity increases with nonpotentiality and complexity. Furthermore,
the relationship between the flare productivity and these measures can be well fitted with a sigmoid function. These results
can be beneficial to future operational flare forecast models. |
