This cartoon assaults the eye, even in humble black and white!
This is one of several cartoons in this important paper, which should really
have catapulted Piddington
into the CSHKP pantheon.
This cartoon was just too imposing to ignore.
The whorls show what
Moore calls the "sheared core" field,
which is held in place by an overlying toroidal field connecting
the model sunspots.
In this paper Piddington also continues his description of twisted flux-tube
emergence.
All in all Piddington seems to have created many of the
concepts we regard as modern today - when one thinks of the innovations
of Giovanelli as well, one has to be impressed by Australian
inventiveness.
And, for sheer visual impact, this cartoon rivals
that of Longcope, which in fact
has no visible shear!
Here everything is attributed to Alfvén-wave transport, except for
particle acceleration (tentatively assigned to magnetic reconnection,
for want of any available microphysics).
The description is in terms of upwards energy flows, however, whereas
the Archivist thinks that some important energy transport must be
downwards.
But this idea has finally caught on.
