title = "Analysis of a relation between subphotospheric plasma flows and photospheric current kernels",
abstract = "Very recently the subphotospheric plasma flows below the sunspots and active regions were revealed by the Time-Distance method of local helioseismology. In this poster we have studied positions of current kernels obtained from vector magnetograms together with maps of kinetic helicity and vorticity at several depths below the photosphere. Vector magnetograms obtained from Marshall Space Flight Center Solar Physics Group internet archive were used together with 3-D velocity fields obtained by Time-Distance method from SOHO/MDI data. The 3-D plasma flow velocities were provided by Dr. Kosovichev. We have found that maxima of vorticity are within an active region and are located at the depth of 3.0 Mm below the photosphere. Maxima of kinetic helicity are dominant within the active region in a depth range 1.8 - 4.5 Mm. The positions of vertical current kernels do agree with positions of observed flare kernels in UV continuum as it is widely believed. The maxima of kinetic helicity are not located directly below the vertical current kernels but they are still in their vicinity.",
