Small-scale topology of solar atmosphere dynamics I: wave sources and wave diffraction

We study the small-scale topology of dynamical phenomena in the quiet-sun internet w ork atmosphere,using short-duration Fourier analysis of high-resolution filtergram sequences to obtain statistical estimates for the co-location probability of different fine-structure elements and wave modes. In this initial paper w e concentrate on the topology of short-duration Fourier amplitude maps for the photosphere and the simultaneously observed o verlying chromosphere. We find that these maps portray acomplex mix of global modes and locally excited w aveswhich necessitates a statistical approach. Variousaspects including mesoscale patterning indicate the presence of subsurface w avesources and of subsurface w avediffraction by convective inhomogeneities
