We used spectral observations of Fe I line profiles with a 200 000 resolutionto determine micro and macroturbulent velocities in the atmospheres of the Sunas a star, {\alpha} Cen A, Procyon ({\alpha} CMi), Arcturus ({\alpha} Boo), andCanopus ({\alpha} Car). Isotropic microturturbulent velocities (V_mi) andradial-tangential macroturbulent velocities (V_ma,RT) were found to be a quitesuitable approximation to the velocity field in the atmospheres of all starsstudied except Canopus. The average velocities V_mi and V_ma,RT are 0.8 +/- 0.1and 2.6 +/- 0.3 km/s for the Sun as a star, 0.8 +/- 0.2 and 2.9 +/- 0.4 km/sfor {\alpha} Cen A, 0.8 +/- 0.3 and 5.9 +/- 0.2 km/s for Procyon, 1.0 +/- 0.2and 4.6 +/- 0.3 km/s for Arcturus. The velocity field in the atmosphere ofCanopus can be described by an anisotropic radial-tangential distribution ofmicroturbulence with V_mi,RT = 2.1 km/s and anisotropic distribution ofmacroturbulence with V_ma,rad = 17 +/- 2 km/s and V_ma,tan = 1.3 +/- 1.0 km/s.From Fourier analysis of broadening and shapes of three spectral lines of Fe I,we have derived the rotation velocity V_e sini = 3.5 +/- 0.2 km/s for Canopus.
