Using a numerical simulation of compressible convection with radiative transfer mimicking the solar photosphere, we compare the velocity eld derived from granule motions to the actual velocity eld of the plasma. We thus test the idea that granules may be used to trace large-scale velocity elds at the suns surface. Our results show that this is indeed the case provided the scale separation is sucient. We thus estimate that neither velocity elds at scales less than 2500 km nor time evolution at scales shorter than 0.5 hr can be faithfully described by granules. At larger scales the granular motions correlate linearly with the underlying fluid motions with a slope of 2 reaching correlation coecients up to0.9.
