Significant advances have been made recently in both the theoretical
understanding and observation of small-scale turbulence in different
layers of the Sun, and in the instabilities that give rise to them. The
general development of solar physics, however, has led to such a degree
of specialization as to hinder interaction between workers in the field.
This book therefore presents studies of different layers and regions of
the Sun, but from the same aspect, concentrating on the study of
small-scale motions. The main emphasis is on the common theoretical
roots of these phenomena, but the book also contains an extensive
treatment of the observational aspects.
