If it is assumed that global-scale motions on the sun are predominantly horizontal and their patterns persist largely unchanged during passage from the east to the west limb, there is a relationship between the Doppler signal and the latitudinal angular-momentum transport which can in principle be tested from observations. This relationship implies that if there is a significant angular-momentum flux towards the equator from higher latitudes in each hemisphere, as predicted by convection theory for maintaining the equatorial acceleration, the mean-square Doppler-velocity signal must be larger east of the central meridian than west of it at the same longitude, in both the northern and southern hemispheres. The difference should be largest at middle latitudes in each hemisphere.
