The relevance of two-dimensional three-component (2D3C) flows goes well beyond their
occurrence in nature, and a deeper understanding of their dynamics might also be helpful in
order to shed further light on the dynamics of pure two-dimensional (2D) or three-
dimensional (3D) flows and vice versa. The purpose of the present paper is to make a step
in this direction through a combination of numerical and analytical work. The analytical part
is mainly concerned with the behavior of 2D3C flows in isolation and the connection …
