    "abstract": "A study of 50 supergranular cells obtained from SOHO Dopplergrams was\nundertaken in order to investigate the relationship between the lifetime ($T$)\nand the horizontal flow velocity ($v_h$) of the cells. For this sample we find\nthat the two parameters are correlated with a relation $v_h\\propto T^{0.5}$ and\n$T$ is identified with the eddy turn-over time. This is in agreement with the\nturbulent convective model of the solar atmosphere where the velocity spectrum\nof supergranular field given by \u0027$v_h \\propto L^{1/3}$\u0027 can be identified with\nthe Kolmogorov spectrum for the eddy size $L$.",
