Abstract
In this review I summarize phenomena observed at the surface and just above the surface of hot stars, in particular phenomena related to the rotation, pulsations and magnetic fields. Thanks to new instruments and tools, such as satellites dedicated to asteroseismology (e.g. CoRoT) and the new generation of spectropolarimeters (e.g. Espadons at CFHT), our knowledge of these phenomena has been progressing very fast in the last few years. Combining these results with what can be obtained with interferometry will provide a global view of hot stars stellar surface phenomena.
