[22] The velocity fields of the prominences can be imagined based on available observations. Prominences are important parts of the turbosphere around the Sun [Pettit, 1951]. Scaling and classification of motions: binary, ternary, and multiparametric approaches were considered in a separate paper [Veselovsky, 2007]. Physical classifications are based on the analysis of the dimensionless parameters and their subordination [Akasofu and Kamide, 2005; Sugiura and Chapman, 1960]. The statistical classification is based on the quantitative sorting between normal and abnormal (extremal) types. Common and specific features of events and structures are better elucidated in this way.
[23] Physically admissible situations on the Sun can be also categorized on statistical grounds as bimodal (e.g., small-large, rare-common, etc.), ternary (e.g., small-middle-large), and polymodal etc. Again, to avoid subjective conclusions and misunderstanding, all this categorizations should be replaced by quantitative delimitation. It can be done when using well-defined restricted and unrestricted conditional distributions.
[24] We can conclude with the trivial, but correct logical statement: all events on the Sun are alike and different depending on our categorizations. Subjective bimodal labels "extreme"-"ordinary", "different"-"similar", "specific"-"common," etc., should be avoided and replaced by more objective semi-quantitative or quantitative categorizations. Otherwise, terminological confusions could happen and obscure the discussions of the physical matter. Unfortunately, it still takes place in the current literature. The correct and one-valued scientific classification should use well-defined quantitative criteria introduced first of all before any a priori accepted paradigms, which can be sometimes misleading or wrong bias of the study. Unfortunately, we also meet such wrong approaches too often and in many instances especially in the recent literature aimed to confirm one universal scenario, which does not exist in reality as was explained earlier.
