The flows in and around sunspots are rich in detail. Starting with theEvershed flow along low-lying flow channels, which are cospatial with thehorizontal penumbral magnetic fields, Evershed clouds may continue this motionat the periphery of the sunspot as moving magnetic features in the sunspotmoat. Besides these well-ordered flows, peculiar motions are found in complexsunspots, where they contribute to the build-up or relaxation of magneticshear. In principle, the three-dimensional structure of these velocity fieldscan be captured. The line-of-sight component of the velocity vector isaccessible with spectroscopic measurements, whereas local correlation orfeature tracking techniques provide the means to assess horizontal propermotions. The next generation of ground-based solar telescopes will providespectropolarimetric data resolving solar fine structure with sizes below 50 km.Thus, these new telescopes with advanced post-focus instruments act as a "zoomlens" to study the intricate surface flows associated with sunspots.Accompanied by "wide-angle" observations from space, we have now theopportunity to describe sunspots as a system. This review reports recentfindings related to flows in and around sunspots and highlights the role ofadvanced instrumentation in the discovery process.
