摘要: Analysis of long-term measurements solar magnetic fields and the flux UV radiation from Sun indicates a cause-effect relationship between activity complexs, their residual fields, coronal holes. A comparison background evolution former complexes reveals unipolar regions that form after decay these complexes. The latitude time in cycles 21–24 is studied. North-South asymmetry manifest distribution migrating toward higher latitudes. It shown that, when opposite polarity reach polar regions, this leads to sign change field decrease area holes, or even complete disappearance. These interactions can explain triple cycle 21 short-term reversals observed 2010 2011.
