Impressive events of magnetic energy release, such as solar and stellar flares and coronal mass ejections, take place in the atmospheric layers above a star's photosphere. These magnetic-activity events are closely related to the dynamics of subsurface convection zones inside the star. IAU Symposium 365 was devoted to observational and theoretical aspects of solar and stellar hydrodynamics and magnetohydrodynamics, both global and local, including numerical studies. The last few decades have been marked by substantial progress in our understanding of the physics of internal and external processes in the Sun and solar-type stars, but the scientific communities making this progress have not traditionally worked closely together. This symposium, delayed due to the COVID pandemic, brought together specialists in the physics of convection zones and atmospheres, to stimulate the emergence of new ideas and to develop new techniques in this dynamic field of active research.

This invaluable book presents a concise but systematic account of the formation of spatial flow structures in a horizontal fluid layer heated from below. Flows of this type, known as Rayleigh-Bénard convection, show important features of behaviour inherent not only in various hydrodynamic-instability phenomena but also in nonlinear pattern-forming processes in other contexts. The book describes the basic methods of investigating convection patterns, and the types of two- and three-dimensional flows, pattern defects, and sequences of convection-regime changes.The author pays special attention to the question of how various factors (mainly reducible to initial and boundary conditions) determine the shapes and sizes of the structures which develop. In this way, the role of order and disorder in flow patterns, as a factor strongly affecting the character of the evolution of structures, is revealed. The presentation emphasizes the physical picture of these phenomena, without excessive mathematical detail.
