A pr 2 00 1 Mesogranulation and Turbulence in Photospheric Flows

Abstract. Below the scale of supergranules we find that cellular flows are present in the solar photosphere at two distinct size scales, approximately 2 Mm and 4 Mm, with distinct characteristic times. Simultaneously present in the flow is a non-cellular component, with turbulent scaling properties and containing 30% of the flow energy. These results are… CONTINUE READING
