Some general characteristics of the observed plasma motions in the actlve region are described. The data concerning the birth and evolution of sunspots, intrinaic internal motiona, the balance of plasma fluxes in individual sunspots and in the active region as a whole are presented. Special attention is paid to rotational plasma motion in sunspots and torsional oscillations of the spots. The.
importance of data on torsional oscillations of aunspots has been established for the study of the magnetic field structure and plasma convection in subphotospheric layers of the Sun.
