摘要：
Large-scale magnetic field on Kitt Peak synoptic charts was investigated for many pairs of consecutive Carrington rotations of the last three solar activity cycles. Evolution of the large-scale magnetic regions can be described by horizontal transport velocity field in many grid points of the solar photosphere. A possible relationship between the current free magnetic field and the deformed force-free magnetic configurations is studied. The aim of the study is to demonstrate a role of dynamical properties of the large-scale magnetic flux during formation of the helical magnetic structures and a preparation of the pre-flare configurations in the solar atmosphere.
