Table 2.

A light-hearted summary of some observable features of selected dynamo models and objects

Type	Rotation dep?	Variability	Morphology
${\mathit{\alpha }}^2$	y	Typically steady	$\equiv$ large-scale (ls)
$\mathit{\alpha }-\mathit{\Omega }$	y	Typically cyclic	ls
Interface $\mathit{\alpha }-\mathit{\Omega }$	y	Typically cyclic	ls
“Essentially nonlin”	?	?	ls or ss
“Turbulent”	n	Chaotic	Small-scale
“Suppressed”	Varies	Varies	ls
MHD sims (global)	y (varies)	Varies	Both
The Sun	y	Cyclic	Both

Each line corresponds to a class of dynamo (or, in the final case, an observed object), and some notation about whether it exhibits rotational dependence, the nature of its typical temporal variability, and its spatial morphology (specifically “large-scale” or “small-scale”, denoted LS and SS respectively).
