It is possible to create an arbitrary pattern of cellular convection by superposing a number of sources, which may have different sizes and strengths. This method is used to simulate the large-scale horizontal flow patterns observed with the SOUP instrument on Spacelab 2. The model of superposed plumes mimics the observed motions remarkably well, especially if one include sinks in addition to sources. Passing test particles ('corks') moving according to the modelled velocity field accumulate in a network pattern that coincides with the magnetic structure observed simultaneously with the SOUP observations.
