摘要: An explanation is suggested for the north-south asymmetry of polar magnetic field reversal in current cycle solar activity. The contribution Babcock-Leighton mechanism to poloidal generation estimated using sunspot data activity cycle. Estimations are performed separately northern and southern hemispheres. hemisphere exceeded considerably that during initial stage This probable reason earlier field. contributions smaller than similar estimations previous cycles. A relatively weak (<1 G) large-scale can be expected next minimum.
