[27] Strongest perturbations on the Sun and in the heliosphere are related to the increase of the global asymmetry, large active regions, sunspots and coronal holes with their more local but powerful attributes like prominences and coronal mass ejections, which often have the transequatorial character. All of them are related to subphotospheric drivers.
[28] Space-time couplings remain not quite clear both in theory and in observations. Because of this, predictability horizons can be not indicated in many instances. The long-term forecast for many days is not attainable without knowledge of the free energy drivers inside the Sun, but visible tracers could be useful in several instances for the expert evaluations.
[29] The shape of eruptive events and their dynamics can be partially understood and explained when using dimensionless physical parameters and simplistic models, which are not universal ones. Classification approaches principles outlined which are based on objective physical and statistical grounds.
