The total photospheric motion field

Brief consideration is given to the conception of the total photospheric motion field. A synthesis of the most thorough investigations is made and the radial Vsup(rad) and tangential Vsup(tg) components of the velocity amplitude of the total photospheric motion field are deduced. At depth log tausub(5)=-3.0 Vsup(rad) and Vsup(tg) have average values of 1.2 and 1.7 kms-1 respectively. They increase smoothly with depth and reach their maximum values of Vsup(rad)=3.0, Vsup(tg)=3.4kms-1 at depths log tausub(5)=-0.2 and log tausub(5)=+0.4 repectively. In the deep photospheric layers both components seem to decrease with depth. (Auth.)
