Abstract

The properties of solar bipoles based on data from magnetic field observations at Mount Wilson Observatory during the period of 1917–2016 are considered. Special attention is given to variations in the size of the bipole magnetic axis during the solar cycle. It is shown that the distribution of the length of the bipole magnetic axis is close to lognormal with the exception of secondary local peaks. Secondary peaks are also present in the distribution of the tilt angles of bipoles at different latitudes. The influence of matter flows in supergranules on the length of the magnetic axis and the tilt angles of sunspot bipoles is discussed.
