On the Physical Nature of the so-Called Prominence Tornadoes

Abstract The term ‘tornado’ has been used in recent years to describe several solar phenomena, from large-scale eruptive prominences small-scale photospheric vortices. It also applied the generally stable quiescent prominences, sparking a renewed interest what historically was called ‘prominence tornadoes’. This paper carries out an in-depth review of physical nature tornadoes’, where their name subconsciously makes us think violent rotational dynamics. However, after careful consideration and analysis published observational data theoretical models, we conclude that tornadoes’ do not differ any substantial way other prominences. There is simply no unequivocal evidence sustained coherent movements would justify distinct category sharing with well-known atmospheric phenomenon. visual impression column-like silhouettes, perceived helical motions, or suggestive Doppler-shift patterns all have simpler, more likely explanation. They are consequence projection effects combined presence oscillations and/or counter-streaming flows. ‘Prominence thus just manifestations complex when observed specific projections. These coincidental viewing angles, together fine-structure dynamics simple yet profoundly distorting effects, may sometimes play havoc our intuitive understanding shapes leading incorrect analogy tornadoes.
