Question: What are solar tornadoes?

Nicolas Labrosse answered on 19 Jun 2017:

‘Solar tornadoes’ happen when we see the gas in the solar atmosphere (normally called ‘plasma’) moving about and appearing to rotate just like a tornado on Earth. However it hasn’t got much in common with tornadoes on Earth. But we don’t really understand what they are. One difficulty is that we see them from only one vantage point, meaning we see them from only one point of view at a time (the Earth, or satellites close to the Earth). So it is difficult to understand how the gas moves in three dimensions. Is it really rotating? If yes, why and how? If not, what is the real motion?
